"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.

"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.

"message_text": "Gregory S.-H. Paek, Myungshin Im, Jinguk Seo, Hyeonho Choi, Hongjae Moon (SNUARC/SNU), Joh-Na Yoon (CBNU), Sumin Lee, Changgon Kim, Soojong Pak (KHU), and Hyun-Il Sung (KASI), on behalf of the GECKO Team\n\n We report optical follow-up observations associated with the LIGO/Virgo/KAGRA gravitational-wave event, S230627c (GCN 34086), conducted with the LOAO, KHAO, CBNUO, and SAO telescopes. The LOAO is a 1.0-meter telescope located in the USA. The KHAO and SAO are 1.0-meter and 0.8-meter telescopes, respectively, located in Korea. The CBNUO is a 0.6-meter telescope with a wide field of view, also located in Korea. Detailed information is in Im+21. The LOAO and KHAO observed the seven highest-scoring host galaxy candidates. The SAO observed one of the optical counterpart candidates, ZTF23aaptsuy/AT2023lxu, reported by ZTF (GCN 34089), and the CBNUO observed the highest-ranked tile with a wide field-of-view (~1.4 deg2).\n\n The host galaxy candidates from the GLADE+ catalog (Dálya+21) were ranked based on a calculated score that combines the probability in the GW localization area with the K-band luminosity, the latter of which is used as a proxy for stellar mass. Each tile for wide field-of-view instruments is ranked by summing the scores of galaxies within the tile.\n\n Observations began at 2023-06-27 04:25 (UT), approximately 0.11 days after the GW alert. For the LOAO images, we subtracted each observed image from the reference image in the r-band from the Pan-STARRS1 surveys (Chambers+16) and filtered transient candidates, which we classified either through parameters from SourceEXtractor (Bertin+96) or visual inspection. Despite our efforts, we could not find any significant signals.\n\n We used the Pan-STARRS1 catalog for flux calibration and employed an AB magnitude system. The preliminary 5 sigma depths of LOAO and KHAO images are as follows:\n------\nOBS OBJECT RANK RA DEC DATE-OBS[UTC] t-t0[days] FILTER EXPTIME[s] DEPTH\nLOAO G135600 0 10:44:53.7 +51:59:22.2 2023-06-27T04:25:33 0.11 R 4860 20.9 \nLOAO G1053369 1 10:48:32.0 +54:05:12.0 2023-06-28T04:12:01 1.10 R 1800 20.8 \nLOAO G1047395 2 10:41:23.0 +46:56:05.0 2023-06-28T04:47:23 1.12 R 1800 20.5 \nLOAO G1079423 3 10:49:12.0 +57:50:13.2 2023-06-29T04:00:59 2.09 R 1800 20.8 \nLOAO G1078790 4 10:51:27.1 +57:42:36.0 2023-06-29T04:46:02 2.12 R 1800 20.7 \nLOAO G1047181 5 10:36:31.9 +45:16:44.4 2023-06-30T03:57:02 3.09 R 1800 20.7\nLOAO G1079513 6 10:51:47.2 +55:23:09.6 2023-06-30T04:34:44 3.11 R 1800 20.7\nKHAO G135600 0 10:44:53.1 +51:59:09.8 2023-06-27T12:10:16 0.43 R 900 16.7\n\n The preliminary 5-sigma depth of the CBNUO image is as follows:\n------\nOBS OBJECT RANK RA DEC DATE-OBS[UTC] t-t0[days] FILTER EXPTIME[s] DEPTH\nCBNUO S230627C 0 11:10:14.110 +75:41:28.640 2023-06-27T12:21:49 0.44 R 300 17.1\n\n The preliminary 5 sigma depths of SAO images are as follows:\n------\nOBS OBJECT DATE-OBS[UTC] t-t0[days] FILTER EXPTIME[s] DEPTH\nSAO AT2023lxu 2023-06-27T12:32:39 0.44 R 120 16.6\nSAO AT2023lxu 2023-07-01T11:45:01 4.41 R 2520 19.7\n\n Gravitational-wave EM Counterpart Korean Observatory (GECKO) is a network of 10+ 0.5m to 1m class telescopes worldwide. The Korea Astronomy and Space Science Institute operates LOAO. We thank the LOAO, KHAO, CBNUO, and SAO operators for their support for the observations.\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg4NjAxNjk0LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.kt-MVP_ziUTtc0K84PUs1btNNXJOMEpu8tFap2sbSFo\n\n",

The flux standard 3c286 was used to calibrate the bandpass response and flux scale of the AMI-LA and J1613+3412 was used as an interleaved complex gain calibrator.\n\nA point source is detected in the AMI-LA image at RA = 16:31:37.30 +/- 0.06 s, Dec = +26:22:01.0 +/- 3.0 arcsec, consistent with the reported position of AT 2023lcr. The source is detected at a flux density of 0.50 +/- 0.05 mJy.\n\nWe plan to perform follow-up observations with the AMI-LA, and encourage further high cadence multi frequency radio observations with other facilities.\n\nWe thank the staff of MRAO for scheduling and performing this observation.\n\n\n---\nTo unsubscribe, open this link in a web browser:\nhttps://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6ImdjbmNpcmN1bGFyQGRldi5ob3Auc2NpbW1hLm9yZyIsInRvcGljcyI6WyJjaXJjdWxhcnMiXSwiaWF0IjoxNjg4NTgzMzY1LCJpc3MiOiJodHRwczovL2djbi5uYXNhLmdvdiJ9.SmzpGKK_lz5TFy2V5W6d6IQYQS1hz2Lsn6ZObqjyjHs\n\n",

"message_text": "The LIGO Scientific Collaboration, the Virgo Collaboration, and the\nKAGRA Collaboration report:\n\nWe identified the compact binary merger candidate S230706ah during\nreal-time processing of data from LIGO Hanford Observatory (H1) and\nLIGO Livingston Observatory (L1) at 2023-07-06 10:43:33.157 UTC (GPS\ntime: 1372675431.157). The candidate was found by the MBTA [1], GstLAL\n[2], PyCBC Live [3], and SPIIR [4] analysis pipelines.\n\nS230706ah is an event of interest because its false alarm rate, as\nestimated by the online analysis, is 4.3e-08 Hz, or about one in 8\nmonths. The event's properties can be found at this URL:\n\nhttps://gracedb.ligo.org/superevents/S230706ah\n\nThe classification of the GW signal, in order of descending\nprobability, is BBH (97%), Terrestrial (3%), NSBH (<1%), or BNS (<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 4%.\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 [6], distributed via GCN notice about 24 seconds after the\ncandidate event time.\n * bayestar.multiorder.fits,2, 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,2. For\nthe bayestar.multiorder.fits,2 sky map, the 90% credible region is\n1553 deg2. Marginalized over the whole sky, the a posteriori\nluminosity distance estimate is 2143 +/- 684 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] Aubin et al.
