Query: Using Galaxy Formation Simulations to optimise LIGO Follow-Up
  Observations   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 two relative to an unweighted search of galaxies, and a factor twenty to a
search over the entire LIGO localization region.
