TITLE: GCN CIRCULAR NUMBER: 27047 SUBJECT: LIGO/Virgo S200213t: Neutrino and galaxies cross-match DATE: 20/02/13 06:25:53 GMT FROM: Varun Bhalerao at Indian Inst of Tech V. Bhalerao (IITB), V. Karambelkar (Caltech) report on behalf of the GROWTH collaboration: We cross-matched the IceCube neutrino candidate (IceCube collaboration, GCN 27043) with the NED galaxies list (Cook et al., GCN 27044) and the possible host galaxy list from Evans (GCN 27045). We find that the following sixteen galaxies from the NED list are within a three-sigma (1.29 degree) radius of the neutrino event. Galaxies from the Evans list are not consistent with the neutrino. In particular, the last few galaxies are at a distance close to the median GW distance for S200213t. Further follow-up is encouraged. objname,ra,dec,z,zunc,DistMpc,DistMod,DistMethod,Separation UGC 02407,44.076,31.897138888889998,0.0150769996,-999.0,62.77894973754883,33.989070892333984,Kinematic,0.9763084646211937 AGC 131378,45.355,32.0175,0.019880000501871,0.00029200001154095,82.77811431884766,34.589576721191406,Kinematic,0.30359019971331863 AGC 123065,45.0025,30.98305555556,0.019917000085115,0.00011999999696855,82.93217468261719,34.5936164855957,Kinematic,0.7774047905727479 UGC 02483,45.403125,31.81925,0.0207540002,3.30000003e-05,84.30000305175781,34.6291389465332,Median,0.18229891713366353 AGC 131380,45.56666666667,30.52944444444,0.020943999290466,0.00011000000085915,87.20848846435547,34.70279312133789,Kinematic,1.2484548573639236 UGC 02393,43.97366666667,32.33491666667,0.0376829989,3.30000003e-05,134.0,35.63552474975586,Median,1.2051072750286012 UGC 02464,45.16794582152001,32.656405944970004,0.0339169987,3.30000003e-05,141.2266082763672,35.74958419799805,Kinematic,0.9170966183061067 AGC 123064,44.635,32.13388888889,0.034370001405478,0.00017299999308307,143.1128692626953,35.77839279174805,Kinematic,0.6270992408508597 AGC 123061,44.02666666667,31.28972222222,0.03583500161767,0.00033700000494719,149.2129669189453,35.86903381347656,Kinematic,1.1047174690169683 CGCG 506-002 NED02,44.91804166667,32.80027777778,0.037533,8e-05,156.2832489013672,35.96956253051758,Kinematic,1.088635020581643 V Zw 302,44.863312085939995,31.385964226389998,0.037593,0.000107,156.5330810546875,35.97303009033203,Kinematic,0.46108812734305843 AGC 123062,44.4725,31.64305555556,0.037838999181986,0.0004870000120718,157.55738830566406,35.9871940612793,Kinematic,0.6349732591350767 V Zw 294,44.54245543191,31.62150440776,0.038193,0.000133,159.03140258789062,36.007415771484375,Kinematic,0.5802981213906651 UGC 02447,44.76825,32.63052777778,0.0382560007,3.30000003e-05,174.0,36.2027473449707,Median,0.9658205967953034 UGC 02507,45.927333333330004,30.6205,0.0536740012,3.30000003e-05,223.49258422851562,36.746315002441406,Kinematic,1.276672609020272 V Zw 317,46.00830931107,31.38939240059,0.0579999983,-999.0,241.50555419921875,36.914634704589844,Kinematic,0.7652394744273816 GROWTH is a worldwide collaboration comprising of Caltech, USA; IPAC, USA, WIS, Israel; OKC, Sweden; JSI/UMd, USA; U Washington, USA; DESY, Germany; MOST, Taiwan; UW Milwaukee, USA; LANL USA; Tokyo Tech, Japan; IIT-B, India; IIA, India; LJMU, UK; TTU, USA; USyd, Australia; and SDSU, USA.
