Abstract
The recent discovery of gravitational radiation from merging black holes
poses a challenge of how to organize the electromagnetic follow-up of
gravitational-wave events as well as observed bursts of neutrinos. We
propose a technique to select the galaxies that are most likely to host
the event given some assumptions of whether the particular event is
associated with recent star formation, low-metallicity stars or simply
proportional to the total stellar mass in the galaxy. We combine data
from the 2-MASS Photometric Redshift Galaxy Catalogue with results from
galaxy formation simulations to develop observing strategies that
potentially reduce the area of sky to search by up to a factor of 2
relative to an unweighted search of galaxies, and a factor of 20 to a
search over the entire LIGO localization region.
