"message_text": "The LIGO Scientific Collaboration, the Virgo Collaboration, and the\nKAGRA Collaboration report:\n\nWe identified the compact binary merger candidate S230911ae during\nreal-time processing of data from LIGO Hanford Observatory (H1) at\n2023-09-11 19:53:24.201 UTC (GPS time: 1378497222.201). The candidate\nwas found by the GstLAL [1] analysis pipeline.\n\nS230911ae is an event of interest because its false alarm rate, as\nestimated by the online analysis, is 1.9e-12 Hz, or about one in 1e4\nyears. The event's properties can be found at this URL:\n\nhttps://gracedb.ligo.org/superevents/S230911ae\n\nThe classification of the GW signal, in order of descending\nprobability, is BBH (>99%), Terrestrial (<1%), NSBH (<1%), or BNS\n(<1%).\n\nAssuming the candidate is astrophysical in origin, the probability\nthat the lighter compact object is consistent with a neutron star mass\n(HasNS) is <1%. [2] Using the masses and spins inferred from the\nsignal, the probability of matter outside the final compact object\n(HasRemnant) is <1%. [2] Both HasNS and HasRemnant consider the\nsupport of several neutron star equations of state. The probability\nthat either of the binary components lies between 3 and 5 solar masses\n(HasMassgap) is <1%.\n\nTwo sky maps are available at this time and can be retrieved from the\nGraceDB event page:\n * bayestar.multiorder.fits,1, an initial localization generated by\nBAYESTAR [3], distributed via GCN notice about 23 seconds after the\ncandidate event time.\n * bayestar.multiorder.fits,2, an initial localization generated by\nBAYESTAR [3], distributed via GCN notice about 4 minutes after the\ncandidate event time.\n\nThe preferred sky map at this time is bayestar.multiorder.fits,2. For\nthe bayestar.multiorder.fits,2 sky map, the 90% credible region is\n24221 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 1758 +/- 588 Mpc (a posteriori mean\n+/- standard deviation).\n\nFor further information about analysis methodology and the contents of\nthis alert, refer to the LIGO/Virgo/KAGRA Public Alerts User Guide\nhttps://emfollow.docs.ligo.org/userguide/.\n\n [1] Tsukada et al. arXiv:2305.06286 (2023) and Ewing et al.\narXiv:2305.05625 (2023)\n [2] Chatterjee et al.

Longo et al. 2023, GCN 34668)\nand Konus-Wind (D. Frederiks et al. 2023, GCN 34659).\n\nThe Fermi GBM Final Localization (GCN 34656) is consistent with the Fermi LAT position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 72 degrees.\n\nThe GBM light curve consists of multiple peaks\nwith a duration (T90) of about 45.6 s (50-300 keV).\nThe time-averaged spectrum from T0-4.4 s to T0+77.6 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff. The power law index is -1.00 +/- 0.01 and\nthe cutoff energy, parameterized as Epeak, is 429.9 +/- 7.8 keV\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.214 +/- 0.007)E-04 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+16.1 s in the 10-1000 keV band\nis 24.8 +/- 0.3 ph/s/cm^2.\n\nA Band function fits the spectrum equally well\nwith Epeak= 420.6 +/- 9.0 keV, alpha = -1.00 +/- 0.01 and beta = -3.02 +/- 0.25.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjk0NDcyMzIwLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.T5K_zo-zUOqVY16jcfFRhiZbCncBhDMlgMK0KQSstKI\n\n",

The BAT ground-calculated position is\nRA, Dec = 226.796, -41.356 deg which is\n RA(J2000) = 15h 07m 11.0s\n Dec(J2000) = -41d 21' 21.2\"\nwith an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment).\nThe partial coding was 95%.\n\nThe mask-weighted light curve shows multiple weak overlapping pulses that\nstart at ~T-9 s and end at ~T+10 s. T90 (15-350 keV) is 16.21 +- 2.89 sec\n(estimated error including systematics).\n\nThe time-averaged spectrum from T-8.63 to T+9.58 sec is best fit by a simple\npower-law model. The power law index of the time-averaged spectrum is\n1.26 +- 0.28. The fluence in the 15-150 keV band is 3.8 +- 0.6 x 10^-7\nerg/cm2.\nThe 1-sec peak photon flux measured from T+2.07 sec in the 15-150 keV band\nis 0.7 +- 0.2 ph/cm2/sec.

Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed the detection of the long-duration GRB 230911B which was also detected by Fermi-GBM (Fermi GBM team, GCN Circ. 34653) along with GRBAlpha and VZLUSAT-2 (Dafcikova et al., GCN Circ. 34664).\n\nThe source was clearly detected in the CZT detectors in the 20-200 keV energy range. The light curve peaks at 2023-09-11 04:25:51.50 UTC. The measured peak count rate associated with the burst is 467 (+56, -35) counts/s above the background in the combined data of all quadrants, with a total of 3390 (+378, -416) counts. The local mean background count rate was 593 (+4, -4) counts/s. Using cumulative rates, we measure a T90 of 15 (+5, -3) s.\n\nThe source was also clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The light curve peaks at 2023-09-11 04:25:51.83 UTC. The measured peak count rate associated with the burst is 790 (+75, -76) counts/s above the background in the combined data of all quadrants, with a total of 4781 (+532, -605) counts. The local mean background count rate was 1400 (+6, -7) counts/s. We measure a T90 of 14 (+7, -3) s from the cumulative Veto light curve.\n\nCZTI is built by a TIFR-led consortium of institutes across India, including VSSC, URSC, IUCAA, SAC, and PRL. The Indian Space Research Organisation funded, managed, and facilitated the project.\n\nCZTI GRB detections are reported regularly on the payload site at:\nhttp://astrosat.iucaa.in/czti/?q=grb\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34677.\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjk0NTI1MzQ2LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.tc6mNHwoUguyiwUI7koD6gXTsUaVQtjJfnGMZK0GkJg\n\n",

Vadawale (PRL) report on behalf of the AstroSat CZTI collaboration:\n\nAnalysis of AstroSat CZTI data with the CIFT framework (Sharma et al., 2021, JApA, 42, 73) showed the detection of a long-duration GRB 240331A which was also detected by the Fermi-GBM (Fermi-GBM Team, GCN Circ. 35998).\n\nThe source was clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The light curve showed multiple peaks of emission with the strongest peak at 2024-03-31 23:55:20.01 UTC. The measured peak count rate associated with the burst is 266 (+69, -53) counts/s above the background in the combined data of all quadrants, with a total of 1926 (+501, -548) counts. The local mean background count rate was 1448 (+8, -9) counts/s. We measure a T90 of 20 (+2, -6) s from the cumulative Veto light curve.\n\nCZTI is built by a TIFR-led consortium of institutes across India, including VSSC, URSC, IUCAA, SAC, and PRL. The Indian Space Research Organisation funded, managed, and facilitated the project.\n\nCZTI GRB detections are reported regularly on the payload site at:\nhttp://astrosat.iucaa.in/czti/?q=grb\n\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/36000.",

"message_text": "The LIGO Scientific Collaboration, the Virgo Collaboration, and the\nKAGRA Collaboration report:\n\nWe identified the compact binary merger candidate S230914ak during\nreal-time processing of data from LIGO Hanford Observatory (H1) and\nLIGO Livingston Observatory (L1) at 2023-09-14 11:14:01.729 UTC (GPS\ntime: 1378725259.729). The candidate was found by the CWB [1], GstLAL\n[2], PyCBC Live [3], and SPIIR [4] analysis pipelines.\n\nS230914ak is an event of interest because its false alarm rate, as\nestimated by the online analysis, is 9e-10 Hz, or about one in 35\nyears. The event's properties can be found at this URL:\n\nhttps://gracedb.ligo.org/superevents/S230914ak\n\nThe classification of the GW signal, in order of descending\nprobability, is BBH (>99%), Terrestrial (<1%), BNS (<1%), or NSBH\n(<1%).\n\nAssuming the candidate is astrophysical in origin, the probability\nthat the lighter compact object is consistent with a neutron star mass\n(HasNS) is <1%. [5] Using the masses and spins inferred from the\nsignal, the probability of matter outside the final compact object\n(HasRemnant) is <1%. [5] Both HasNS and HasRemnant consider the\nsupport of several neutron star equations of state. The probability\nthat either of the binary components lies between 3 and 5 solar masses\n(HasMassGap) is <1%.\n\nTwo sky maps are available at this time and can be retrieved from the\nGraceDB event page:\n * bayestar.multiorder.fits,0, an initial localization generated by\nBAYESTAR [6], distributed via GCN notice about 24 seconds after the\ncandidate event time.\n * bayestar.multiorder.fits,1, an initial localization generated by\nBAYESTAR [6], distributed via GCN notice about 5 minutes after the\ncandidate event time.\n\nThe preferred sky map at this time is bayestar.multiorder.fits,1. For\nthe bayestar.multiorder.fits,1 sky map, the 90% credible region is\n1863 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 2826 +/- 745 Mpc (a posteriori mean\n+/- standard deviation).\n\nFor further information about analysis methodology and the contents of\nthis alert, refer to the LIGO/Virgo/KAGRA Public Alerts User Guide\nhttps://emfollow.docs.ligo.org/userguide/.\n\n [1] Klimenko et al.

The event was selected by the ICECUBE_Astrotrack_BRONZE alert stream. The average astrophysical neutrino purity for Bronze alerts is 30%. This alert has an estimated false alarm rate of 0.8823 events per year due to atmospheric backgrounds. The IceCube detector was in a normal operating state at the time of detection.\n\nAfter the initial automated alert (https://gcn.gsfc.nasa.gov/notices_amon_g_b/138354_45413430.amon) more sophisticated reconstruction algorithms have been applied offline, with the direction refined to:\n\nDate: 2023-08-23\nTime: 05:21:03.71 UT\nRA: 163.83 (+2.60 / -2.02 deg 90% PSF containment) J2000\nDec: +31.83 (+1.79 / - 2.13 deg 90% PSF containment) J2000\n\nWe encourage follow-up by ground and space-based instruments to help identify a possible astrophysical source for the candidate neutrino.\n\nTwo Fermi 4FGL-DR4 sources are located in the 90% uncertainty region of the event. The sources are 4FGL J1051.6+3253 (NGC 3434) at RA 162.91, Dec +32.88 and 4FGL J1102.9+3014 at RA 165.74, Dec +30.24, located 1.31 and 2.28 deg away from the best fit position, respectively.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica.

All the requested event mode data was delivered to the ground.\n\nThe BAT likelihood search, NITRATES (DeLaunay + Tohuvavohu 2022, ApJ, 941, 169), performed on the temporal window [T0-20 s, T0+20 s], detects the burst with a sqrt(TS) of 109.13 in a 16 s analysis time bin, starting at T0 - 12 s. The burst has a multi-peak structure with a duration of ~30 s in the BAT rates curve.\n\nNITRATES results are consistent with a burst coming from outside the FOV, with DeltaLLHOut of -578.9.\n\nSee Section 9.1 and Figures 10 and 17 in the NITRATES paper for brief descriptions and interpretation of sqrt(TS), DeltaLLHPeak, and DeltaLLHOut.\n\nGUANO is a fully autonomous, extremely low latency, spacecraft commanding pipeline designed for targeted recovery of BAT event mode data around the times of compelling astrophysical events to enable more sensitive GRB searches.\n\nA live reporting of Swift/BAT event data recovered by GUANO can be found at: https://www.swift.psu.edu/guano/\n\n\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34873.",

Ambrosi (INAF-IASFPA) and\nP.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:\n\nSwift-XRT has performed follow-up observations of the\nFermi/GBM-detected burst GRB 230911A, collecting 2.8 ks of Photon\nCounting (PC) mode data between T0+215.5 ks and T0+326.2 ks.\n\nAn uncatalogued X-ray source is detected consistent with the GOTO\nposition (GCN Circ. 34681) of the fading optical counterpart candidate,\nand this is therefore believed to be the afterglow. The position of\nthis source (astrometrically enhanced by using the XRT-UVOT alignment\nand matching UVOT field sources to the USNO-B1 catalogue) is RA,\nDecW.5027, -29.8259 which is equivalent to:\n\nRA (J2000): 03:50:0.65\nDec(J2000): -29:49:33.2\n\nwith an uncertainty of 3.4 arcsec (radius, 90% confidence). Position\nenhancement is described by Goad et al. (2007, A&A, 476, 1401) and\nEvans et al. (2009, MNRAS, 397, 177). This position is 3.1 arcsec from\nthe GOTO position.\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/00021622.\nThe results of the full analysis of the XRT observations are available\nat https://www.swift.ac.uk/ToO_GRBs/00021622.\n\nThis circular is an official product of the Swift-XRT team.\n\n\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34702.\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjk0NzU5MzgyLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.oc9DWXDIoa2Z_ryG1TZ75XiwZXSLUcITs6fzUrnv-X8\n\n",

"message_text": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nIceCube has performed a search [1] for additional track-like muon neutrino events arriving from the direction of IceCube-230914A (https://gcn.nasa.gov/circulars/34693) in a time range of 1000 seconds centered on the alert event time (2023-09-14 05:12:43.710 UTC to 2023-09-14 05:29:23.710 UTC) during which IceCube was collecting good quality data. Excluding the event that prompted the alert, zero track-like events are found within the 90% containment region of IceCube-230914A. The IceCube sensitivity to neutrino point sources with an E^-2.5 spectrum (E^2 dN/dE at 1 TeV) within the locations spanned by the 90% spatial containment region of IceCube-230914A is 1.4e-01 GeV cm^-2 in a 1000 second time window. 90% of events IceCube would detect from a source at this declination with an E^-2.5 spectrum have energies in the approximate energy range between 2e+02 GeV and 7e+04 GeV.\n\nA subsequent search was performed including 2 days of data centered on the alert event time (2023-09-13 05:21:03.710 UTC to 2023-09-15 05:21:03.710 UTC). In this case, we report a p-value of 1.00, consistent with no significant excess of track events. The IceCube sensitivity to neutrino point sources with an E^-2.5 spectrum (E^2 dN/dE at 1 TeV) within the locations spanned by the 90% spatial containment region of IceCube-230914A is 1.6e-01 GeV cm^-2 in a 2 day time window.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the geographic South Pole, Antarctica. The IceCube realtime alert point of contact can be reached at roc@icecube.wisc.edu.\n\n[1] IceCube Collaboration, R.

"message_text": "C. Peña (Univ. of Utah), D. B. Malesani (Radboud univ. and DAWN/NBI), A. Rossi (INAF), A. J. Levan (Radboud univ.), and G. Pugliese (API, Amsterdam), report on behalf of the Stargate collaboration:\n\nFollowing the Chandra X-ray localization (OâConnor et al., GCN 34672) of the Fermi/GBM short GRB 230906A (Fermi GBM team, GCN 34631; Frederiks et al., GCN 34638), we observed the GRB afterglow with the ESO Very Large Telescope equipped with the HAWK-I near infrared camera and with the FORS2 optical camera. Observations in the HAWK-I Ks band consisted in 30 minute exposure with a mean time of 6.84 days after the GRB. Observations in the FORS2 R band consisted in 40 minute exposure with a mean time of 6.76 days after the GRB. Sky conditions were modest, with a delivered seeing of ~2\" in the R band.\n\nConsistent with the position of the X-ray afterglow discovered by Chandra (OâConnor et al., GCN 34672), we detect a weak source in the stacked R-band image, at J2000 coordinates (~0.5\" error):\n\nRA = 05:19:01.57\nDec = -47:53:32.3\n\nWe measure for this source an AB magnitude R = 25.44 ± 0.25, calibrated against nearby SkyMapper stars. In the Ks band, we can only set an upper limit with AB magnitude > 23.3. As noted by OâConnor et al. (GCN 34672), there is no detected host galaxy in the Legacy Survey, which has however a depth shallower than our measurement.\n\nWhile the spatial association with the X-ray counterpart suggests a physical connection with the GRB, it is unclear whether the source is dominated by transient light or is a faint host galaxy. We note that the R-K color is not as red as was AT 2017gfo at a comparable epoch after explosion (e.g. Villar et al. 2017, ApJ, 851, L21).\n\nWe acknowledge the support of the observing staff at Paranal, in particular Ana Escorza, Linda Schmidtobreick, and Fuyan Bian.\n\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34704.\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjk0ODEyOTE3LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.GLnFhEKmUWb5nrW1n9Bn7rpXEOjcKiDqolyeCN_FWaU\n\n",

"message_text": "O.J. Roberts (USRA/NASA-MSFC) and C. Meegan (UAH)\nreport on behalf of the Fermi Gamma-ray Burst Monitor Team:\n\n\"At 03:09:32.88 UT on 11 September 2023, the\nFermi Gamma-ray Burst Monitor (GBM) triggered and located\nGRB 230911A (trigger 716094577/230911132), which was also\ndetected by Swift/XRT (P. D'Avanzo et al. 2023, GCN 34702)\nand GOTO (S. Belkin et al. 2023, GCN 34681). The Fermi GBM\nFinal Real-time Localization reported in GCN 34652 is\nconsistent with the Swift-XRT and GOTO localizations.\n\nThe angle from the Fermi LAT boresight is 54 degrees.\n\nThe GBM light curve consists of a single peak with a\nduration (T90) of about 36 s (50-300 keV). The time-averaged\nspectrum from T0-4 to T0+30 s is best fit by a Band function\nwith Epeak= 98 +/- 21 keV, alpha = -1.1 +/- 0.1 and\nbeta = -2.0 +/- 0.1.\n\nThe event fluence (10-1000 keV) in this time interval is\n(6.2 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+2.0 s in the 10-1000 keV band is 3.7 +/- 0.2 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"\n\n\nView this GCN Circular online at https://gcn.nasa.gov/circulars/34720.\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjk0OTEwNDg0LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.bDrt1NHD1P-0fD3mqEGugJTR709i66vu04Tb50uiOdY\n\n",
