TITLE: GCN CIRCULAR NUMBER: 21519 SUBJECT: LIGO/Virgo G298048: Nearby Galaxies in the Localization Volume DATE: 17/08/17 20:00:07 GMT FROM: Mansi M. Kasliwal at Caltech David O. Cook (Caltech), Angela Van Sistine (UW Milwaukee), Leo Singer (NASA/GSFC), and M. M. Kasliwal (Caltech) report on behalf of the GROWTH (Global Relay of Observatories Watching Transients Happen) collaborations We spatially cross-matched the LIGO/Virgo G298048 trigger (90% containment volume using bayestar-HLV.fits; LVC GCN 21513) with our Census of the Local Universe (CLU; Cook et al. in prep) galaxy catalog and found 54 galaxies. This catalog is a compilation of galaxies with existing redshifts from many sources (e.g., NED, SDSS, etc) and new galaxies from a 3PI four-filter narrow-band survey to look for redshifted Halpha emission out to 200 Mpc with the Palomar Oschin 48-inch telescope. The narrow-band survey is limited to a declination above -20 degrees, thus all galaxies within the 90% volume come from the compiled CLU catalog with no Halpha overlap. We list here all 54 galaxies sorted by stellar mass (Mstar) for galaxies whose location on the sky and distance falls in the 90% volume reported by the BAYESTAR probability sky map (Singer et al. 2016). We also list the dust-corrected star formation rates (SFRs) for galaxies with GALEX FUV detections and a 'nan' for those with no detection. In addition, we have cross-matched the CLU catalog with the IceCube source closest to the LIGO localization (GCN #21511) and found 1 galaxy in the quoted error circle (ra=182.0 deg; dec=-3.2 deg; radius=0.9 deg) and a distance less than 50 Mpc. This galaxy in presented at the bottom of the table below and is marked by '**'. Finally, we have compared CLU to the GLADE results posted in the GCN #21516 and found that all 15 galaxies reported by GLADE are a subset of our 54 galaxies in the 90% LIGO volume.
