TITLE: GCN CIRCULAR NUMBER: 20800 SUBJECT: LIGO/Virgo G275404: Nearby Galaxies in the Localization Volume DATE: 17/03/03 01:11:14 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 iPTF (intermediate Palomar Transient Factory) and GROWTH (Global Relay of Observatories Watching Transients Happen) collaborations We spatially cross-matched the LIGO/Virgo G275697 trigger (90% containment volume; LVC GCN 20763) with our Census of the Local Universe (CLU; Cook et al. in prep) galaxy catalog and found 7361 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. Currently, the narrow-band survey is only calibrated inside the footprint of SDSS. Of the 7361 galaxies in the error volume, 6032 come from a compilation of known galaxies and 1329 are new, emission-line CLU galaxy candidates. We list here the top 20 galaxies sorted by star formation rate (SFR) and 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), where the 90% credible volume measures 3.3e6 Mpc^3. The sorted SFR list contains 2 new CLU galaxies with no previous spectroscopic redshifts, and the sorted mass list contains 1 new CLU galaxy. CLU J20203032+0734271 is an interacting triplet of galaxies, and CLU J08550651+1944566 may be an interacting pair.

(2011) and have been corrected for internal dust extinction using a combination of GALEX FUV and 22um ALLWISE fluxes (Hao et al. 2011). The quoted stellar masses are derived from 3.4um ALLWISE fluxes and a mass-to-light ratio of 0.5 (McGaugh & Schombert et al. 2015). AGN contributions to the SFRs and stellar masses are not corrected for.
