"message_text": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nA search for track-like muon neutrino events detected by IceCube consistent with the sky\nlocalization of the low-significance gravitational wave candidate S230701z in a time range of 1000 seconds\ncentered on the alert event time (2023-07-01 06:28:35 UTC to 2023-07-01 06:45:15 UTC)\nhas been performed [1,2]. During this time period IceCube was collecting good quality data.\nOne hypothesis test was conducted for this low-significance gravitational wave event. The\nsearch uses a Bayesian approach to quantify the joint GW + neutrino event significance, which\nassumes a binary merger scenario and accounts for known astrophysical priors, such as GW source\ndistance, in the significance estimate [3].\n\nOne track-like event is found in spatial and temporal coincidence with the gravitational-wave\ncandidate S230701z calculated from the map circulated by LVK as S230701z-2-Preliminary. This\nrepresents an overall pre-trial p-value of 0.0018 for the Bayesian search. The most probable multi-messenger source direction based on the neutrinos and GW skymap is RA 114.94, Dec 15.16 degrees.\n\nThe reported p-value here does not account for any trials correction (multiple hypotheses testing). The false alarm rate of these coincidences can be obtained by multiplying the p-values with their corresponding GW trigger rates. Further details are available at https://gcn.nasa.gov/missions/icecube.\n\nProperties of the coincident event(s) are shown below.\n\ndt(s)\tRA(deg)\t\tDec(deg)\tAngular uncertainty(deg) p-value(generic transient) p-value(Bayesian)\n-----------------------------------------------------------------------------------------------------\n172.17 114.94 \t15.16 \t2.58 \t\tnull (not applicable) \t0.0018\n...\n\nwhere:\ndt = Time of track event minus time of GW trigger (sec)\nAngular uncertainty = Angular uncertainty of track event: the radius of a circle\n \trepresenting 90% CL containment by area.\np-value = the p-value for this specific track event from each search.\n\nThe IceCube Neutrino Observatory is a cubic-kilometer neutrino detector operating at the\ngeographic South Pole, Antarctica.

Chastain (UNM) on behalf of the PanRadio GRB collaboration\n\nThe Australia Telescope Compact Array (ATCA) rapidly performed observations of the long GRB 230628E (Klingler et al. GCN 34110) at 5.5, 9, 16.7 and 21.2 GHz as part of the Large ATCA âPanRadio GRBâ follow-up programme C3542 (PI. Anderson). ATCA was on target observing at 2023-06-29 02:11 UT when the source had risen above the horizon, just 3.75 hrs post-burst and observed for 10.5 hrs. There is no radio source coincident with the enhanced XRT position (Page et al. GCN 34116) with 3 sigma upper limits of 44, 39, 54 and 78 microJy/beam at 5.5, 9.0, 16.7 and 21.2 GHz, respectively. Further observations are planned.\n\nWe thank the CSIRO Space and Astronomy staff for supporting these observations and maintaining the ATCA rapid-response observing mode.\n\nWe acknowledge the Gomeroi people as the traditional owners of the Observatory site. The Australia Telescope Compact Array is part of the Australia Telescope National Facility (https://ror.org/05qajvd42) which is funded by the Australian Government for operation as a National Facility managed by CSIRO.\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg4MjczNjE0LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.0yQAgR1HUOxkFIx5SGl0-4dyUNn5AQ25jrFP-GatYsE\n\n",

"message_text": "The LIGO Scientific Collaboration, the Virgo Collaboration, and the\nKAGRA Collaboration report:\n\nWe identified the compact binary merger candidate S230702an during\nreal-time processing of data from LIGO Hanford Observatory (H1) and\nLIGO Livingston Observatory (L1) at 2023-07-02 18:54:53.738 UTC (GPS\ntime: 1372359311.738). The candidate was found by the CWB [1], MBTA\n[2], GstLAL [3], PyCBC Live [4], and SPIIR [5] analysis pipelines.\n\nS230702an is an event of interest because its false alarm rate, as\nestimated by the online analysis, is 1.5e-12 Hz, or about one in 1e4\nyears. The event's properties can be found at this URL:\n\nhttps://gracedb.ligo.org/superevents/S230702an\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%. [6] Using the masses and spins inferred from the\nsignal, the probability of matter outside the final compact object\n(HasRemnant) is <1%. [6] 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 [7], distributed via GCN notice about 21 seconds after the\ncandidate event time.\n * bayestar.multiorder.fits,1, an initial localization generated by\nBAYESTAR [7], 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\n2519 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 2567 +/- 770 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.

"message_text": "We observed the ZTF23aaptsuy/AT2023lxu transient (Anumarlapudi et. al, GCN 34089), found in the localization region of LVK S230627c (LVK collaboration, GCN 34086), using the AS-32 telescope on 2023-06-27 (UT) 17:45:15 and 2023-07-01 (UT) 17:56:01. Since we cannot discriminate the source of ZTF23aaptsuy/AT2023lxu from the host galaxy due to FWHM of about 3.7\" we performed (1) aperture photometry of the host galaxy and (2) subtraction of stacked images of the two epochs. (1) Preliminary photometry of the host galaxy (+ ZTF23aaptsuy/AT2023lxu source) is following:\n\nDate UT start t-T0,d Exp. Filter galaxy Err.

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 GRB 230701B which was also detected by Fermi (Trig. 709864601).\n\nThe source was clearly detected in the CsI anticoincidence (Veto) detector in the 100-500 keV energy range. The light curve peaks at 2023-07-01 00:36:40.91 UTC. The measured peak count rate associated with the burst is 259 (+71, -40) counts/s above the background in the combined data of all quadrants, with a total of 2144 (+493, -544) counts. The local mean background count rate was 1470 (+5, -5) counts/s. We measure a T90 of 27 (+1, -7) 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\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg4Mzc1NjU1LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.NX-6E8MaDfWVGXCQ6n08zysvrtshn8LbDr8mDqL4cmc\n\n",

"message_text": "The LIGO Scientific Collaboration, the Virgo Collaboration, and the\nKAGRA Collaboration report:\n\nWe identified the compact binary merger candidate S230704f during\nreal-time processing of data from LIGO Hanford Observatory (H1) and\nLIGO Livingston Observatory (L1) at 2023-07-04 02:12:11.224 UTC (GPS\ntime: 1372471949.224). The candidate was found by the CWB [1], MBTA\n[2], and GstLAL [3] analysis pipelines.\n\nS230704f is an event of interest because its false alarm rate, as\nestimated by the online analysis, is 2.8e-09 Hz, or about one in 11\nyears. The event's properties can be found at this URL:\n\nhttps://gracedb.ligo.org/superevents/S230704f\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%. [4] Using the masses and spins inferred from the\nsignal, the probability of matter outside the final compact object\n(HasRemnant) is <1%. [4] 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 [5], distributed via GCN notice about 23 seconds after the\ncandidate event time.\n * bayestar.multiorder.fits,1, an initial localization generated by\nBAYESTAR [5], 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\n1948 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 2965 +/- 978 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.

Palazzi (INAF-OAS) report on behalf of the CIBO collaboration:\n\nWe observed the field of the long GRB 230328B detected by Fermi-GBM (Fermi GBM Team, GCN 33526; Dalessi et al., GCN 33531), Swift-BAT (Gropp et al., GCN 33527), AstroSat-CZTI (Waratkar et al., GCN 33532), GRBAlpha (Dafcikova et al., GCN 33543), and Konus-Wind (Svinkin et al., GCN 33544). We obtained 20 min of g'- and r'-band imaging with the LBC camera mounted on LBT (Mt Graham, AZ, USA) on 2023-06-23, ~3 months after the burst trigger. Observations were performed under mediocre weather conditions with a strong SW wind and thus an average seeing of ~2\".\n\nAt the location of the optical afterglow (Pankov et al., GCN 33528; Belkin et al., GCN 33530; Lu et al., GCN 33534; Catapano et al., GCN 33535; Suresh et al., GCN 33536; Adami et al., GCN 33537; Gompertz et al., GCN 33538; Komesh et al., GCN 33539; Kumar et al., GCN 33547; Kugel et al., GCN 33550; Siegel et al., 33556; Pozanenko et al., GCN 33559), we detect a faint source which is likely the GRB host galaxy. We measure the following AB magnitudes:\n\ng 24.2 +- 0.3\nr 23.8 +- 0.2\n\ncalibrated against PanSTARRS field stars, and not corrected for the foreground Galactic extinction.\n\nWe acknowledge the excellent support from the LBTO and LBT-INAF staff, particularly D. Thompson, D. Gonzalez Huerta, F. Cusano and D. Paris, in obtaining these observations.\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg4NDgwMDgwLCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.QS0AIR7nyPMhRA-RguUj1SLJV9FaQpPbWDOS_lPDG4c\n\n",

"message_text": "The IceCube Collaboration (http://icecube.wisc.edu/) reports:\n\nIceCube has performed an additional search for track-like muon neutrino events consistent with the sky localization of the joint skymap for low significance gravitational-wave candidate S230619bd and GBM-230619 (https://gcn.nasa.gov/circulars/34054) in a time range of -0.1 day, +14 days from the GW alert event time (2023-06-19 17:01:06.4 UTC to 2023-07-03 19:25:06.4 UTC). During this time period IceCube was collecting good quality data. This is a maximum likelihood analysis which searches for a generic point-like neutrino source coincident with the given GW skymap [1,2].\n\nIn this case, we report a p-value of 0.31, consistent with no significant excess of track events. IceCube's sensitivity assuming an E^-2 spectrum (E^2 dN/dE) to neutrino point sources within the locations spanned by the 90% spatial containment of the joint skymap ranges from 0.037 to 0.061 GeV cm^-2 in this time window.\n\nA Bayesian search [1,2] was also performed, using the standard time window of 1000 seconds centered on the alert event time (2023-06-19 19:16:46 UTC to 2023-06-19 19:33:26 UTC), and using the the map for S230619bd circulated in the 2-Preliminary notice. This search uses a Bayesian approach to quantify the joint GW + neutrino event significance, which assumes a binary merger scenario and accounts for known astrophysical priors, such as GW source distance, in the significance estimate [3]. For this search we report a p-value of 0.22, consistent with no significant events coincident with the map. IceCube's sensitivity assuming an E^-2 spectrum (E^2 dN/dE) to neutrino point sources within the locations spanned by the 90% spatial containment of the 2-Preliminary map ranges from 0.0277 to 1.0771 GeV cm^-2 in a 1000 second 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] M. G. Aartsen et al 2020 ApJL 898 L10\n[2] Abbasi et al. Astrophys.J. 944 (2023) 1, 80\n[3] I.
