TITLE: GCN CIRCULAR NUMBER: 27093 SUBJECT: LIGO/Virgo S200213t: Possible host galaxies in the bilby skymap DATE: 20/02/16 02:56:43 GMT FROM: Phil Evans at U of Leicester P.A. Evans (U. Leicester) reports, The bilby.fits.gz,0 GW skymap has been convolved with the 2MPZ galaxy catalogue (Bilicki et al., ApJS, 210, 9), using the method described in Evans et al (2016, MNRAS, 462, 1591*), to identify a ranked list of potential host galaxies of the LVC trigger S200213t. This galaxy ranking method accounts for the (line-of-sight dependent) completeness of 2MPZ, GW probability, and the overlap between P(D) functions for the GW event and the individual galaxies. In total 4040 galaxies with P>10^-5 have been identified. The most probable 20 are listed below, a full list and more details are available at https://www.swift.ac.uk/LVC/S200213t/galaxies | Galaxy name | P_host | RA | Dec | K_mag | GalDist | -------------------------------------------------------------------------------------------------- | 2MPZ J01154286+5559475 | 8.01e-03 | 01h 15m 42.86s | +55d 59' 47.4" | 10.9 | 172.1 +/- 7.4 | | 2MPZ J01215577+5601372 | 7.31e-03 | 01h 21m 55.78s | +56d 01' 37.2" | 11.0 | 179.3 +/- 7.4 | | 2MPZ J00585413+5236357 | 7.22e-03 | 00h 58m 54.14s | +52d 36' 35.6" | 10.4 | 135.4 +/- 7.4 | | 2MPZ J00402207+4141070 | 6.41e-03 | 00h 40m 22.08s | +41d 41' 07.1" | 5.7 | 61.1 +/- 42.9 | | 2MPZ J01161702+5352580 | 6.07e-03 | 01h 16m 17.02s | +53d 52' 58.1" | 11.3 | 197.7 +/- 7.4 | | 2MPZ J01183038+5156442 | 5.67e-03 | 01h 18m 30.38s | +51d 56' 44.2" | 9.7 | 124.3 +/- 7.4 | | 2MPZ J00592750+5222015 | 5.65e-03 | 00h 59m 27.50s | +52d 22' 01.6" | 11.2 | 163.7 +/- 7.4 | | 2MPZ J00585906+5238557 | 5.48e-03 | 00h 58m 59.06s | +52d 38' 55.7" | 10.6 | 129.6 +/- 7.4 | | 2MPZ J00513895+5205260 | 4.64e-03 | 00h 51m 38.95s | +52d 05' 26.2" | 9.9 | 116.3 +/- 7.4 | | 2MPZ J01192705+5831151 | 4.44e-03 | 01h 19m 27.05s | +58d 31' 15.2" | 10.0 | 151.8 +/- 47.9 | | 2MPZ J01311381+5545126 | 4.12e-03 | 01h 31m 13.82s | +55d 45' 12.6" | 10.7 | 160.6 +/- 7.4 | | 2MPZ J00544651+5108434 | 4.03e-03 | 00h 54m 46.51s | +51d 08' 43.4" | 11.2 | 196.5 +/- 7.4 | | 2MPZ J01014603+5556556 | 4.00e-03 | 01h 01m 46.03s | +55d 56' 55.7" | 10.8 | 177.0 +/- 7.4 | | 2MPZ J01291379+5600241 | 3.92e-03 | 01h 29m 13.80s | +56d 00' 24.1" | 11.2 | 172.4 +/- 7.4 | | 2MPZ J01033453+5225416 | 3.89e-03 | 01h 03m 34.54s | +52d 25' 41.5" | 11.4 | 141.8 +/- 7.4 | | 2MPZ J01025660+5120324 | 3.82e-03 | 01h 02m 56.62s | +51d 20' 32.6" | 10.3 | 111.8 +/- 7.4 | | 2MPZ J01022406+5214345 | 3.80e-03 | 01h 02m 24.07s | +52d 14' 34.4" | 11.2 | 135.3 +/- 7.4 | | 2MPZ J01313530+5534046 | 3.64e-03 | 01h 31m 35.30s | +55d 34' 04.8" | 10.9 | 172.6 +/- 7.4 | | 2MPZ J00110106+3003072 | 3.39e-03 | 00h 11m 1.06s | +30d 03' 07.2" | 10.0 | 98.7 +/- 7.4 | | 2MPZ J00583689+5137088 | 3.34e-03 | 00h 58m 36.89s | +51d 37' 08.8" | 10.4 | 111.2 +/- 7.4 | -------------------------------------------------------------------------------------------------- (* See also the erratum: MNRAS, 484, 2362; or arXiv 1606.05001 for the full manuscript with erratum applied).
