Kasliwal (Caltech)\n\nreport on behalf of the GROWTH (Global Relay of Observatories Watching\nTransients Happen) collaboration\n\nWe spatially cross-matched the LIGO/Virgo G298048 trigger with the\nassumption of face-on orientation (90% containment volume using\nbayestar-HLV-face-on.fits; LVC GCN 21513) with our Census of the Local\nUniverse (CLU; Cook et al. in prep) galaxy catalog and found 13 galaxies.\nThis catalog is a compilation of galaxies with existing redshifts from many\nsources (e.g., NED, SDSS, etc) and new galaxies from a 3PI four-filter\nnarrow-band survey to look for redshifted Halpha emission out to 200 Mpc\nwith the Palomar Oschin 48-inch telescope. The narrow-band survey is\nlimited to a declination above -20 degrees, thus all galaxies within the\n90% volume come from the compiled CLU catalog with no Halpha overlap.\n\nWe list here all 13 galaxies sorted by stellar mass (Mstar) for galaxies\nwhose location on the sky and distance falls in the 90% volume reported by\nthe BAYESTAR probability sky map (Singer et al. 2016). We also list the\ndust-corrected star formation rates (SFRs) for galaxies with GALEX FUV\ndetections and a 'nan' for those with no detection.\n\nOf the 13 galaxies, 4 galaxies are not in the list of 54 galaxies reported\nin GCN #21519 without the face-on assumption. The new galaxies are marked\nwith a ���*���.\n\n                 name_NED                    ra      dec    distmpc\nlogsfr_fuv logmstar dm_kin       P\n----------------------------------------- -------- -------- -------\n---------- -------- ------ --------------\n                                 NGC 4830 194.3663 -19.6913   47.90\n-1.419    10.41  33.40 0.600362551579\n                           MCG -04-31-042 198.5739 -26.5827   54.70\nnan     9.98  33.69 0.820306676922*\n                  2MASX J12525109-1529300 193.2130 -15.4916   52.26\nnan     9.31  33.59 0.807651962502\n                  2MASX J12573271-1942006 194.3863 -19.7002   52.39\n-1.788     9.25  33.60 0.723692228565\n                  2MASX J12551928-1456593 193.8304 -14.9499   48.56\nnan     9.22  33.43 0.801217259508*\n                                  IC 3825 192.6544 -14.4828   51.04\n-0.985     9.17  33.54 0.776579689512\n                  2MASX J13073768-2356181 196.9071 -23.9384   49.73\nnan     8.92  33.48 0.634606246205\n                WINGS J125412.84-153523.6 193.5534 -15.5899   50.96\nnan     8.64  33.54 0.595385148382\n                      6dF J1254495-160308 193.7063 -16.0523   48.02\nnan     8.52  33.41 0.197814505144\n             GALEXASC J125259.36-152150.9 193.2474 -15.3639   49.87\n-1.321     8.41  33.49 0.419676266799\n             GALEXASC J125157.02-160617.8 192.9872 -16.1047   50.30\nnan     8.06  33.51 0.410982650697\n             GALEXASC J125404.25-145044.4 193.5173 -14.8457   50.85\n-1.659     7.75  33.53 0.823290805821*\n                           MCG -02-33-014 192.3380 -13.3512   49.57\nnan      nan  33.48  0.82251638918*\n\n* Galaxies not reported in the CLU crossmatch to LIGO with no orientation\nassumptions (GCN #21519).\n\nThe SFRs are derived from GALEX all sky kron FUV magnitudes via the\nprescription of Murphy et al.
