Subject
LIGO/Virgo G298048: Nearby Galaxies in the Localization Volume

(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. The matched galaxies are marked by '*'

**Galaxy found within the IceCube localization closest to the LIGO
localization in the GCN #21511.
* Galaxies matched to the GLADE catalog reported in  GCN #21516

The SFRs are derived from GALEX all sky kron FUV magnitudes via the
prescription of Murphy et al. (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).
