TITLE: GCN CIRCULAR NUMBER: 18340 SUBJECT: LIGO/Virgo G184098: Nearby Galaxies in Error Circle DATE: 15/09/20 01:48:52 GMT FROM: Mansi M. Kasliwal at Caltech M. M. Kasliwal (Caltech), J. K. Cannizzo (NASA/UMBC), N. Gehrels (NASA GSFC) and P. Evans (U. Leicester) report on behalf of a larger collaboration We cross-matched the LIGO/Virgo G184098 trigger (95% containment contour) with our Census of the Local Universe (CLU) galaxy catalog. The biggest, nearby galaxy is of course the Large Magellanic Cloud. But if we limit our search to galaxies that constitute the top half of the Schechter function in the 80 Mpc volume, we find about 170 galaxies. Furthermore, weighing the galaxy luminosity with the underlying containment probability, here are the top ten potential host galaxies in our list: Name RA(J2000) DEC(J2000) ESO088-G017 112.250 -66.897 NGC2442 114.099 -69.531 IC2202 111.977 -67.574 ESO090-G011 134.577 -65.368 NGC3110 151.009 -6.475 NGC3145 152.541 -12.434 NGC2967 145.514 0.336 ESO126-G003 138.663 -60.434 NGC2187A 90.934 -69.588 NGC2150 88.943 -69.561 We caution that the probability contained in these galaxies is a small fraction of the total. Yet, these may be interesting for deeper searches where wide-angle is unavailable. For example, see Evans et al. notice for Swift satellite follow-up of this trigger.
