A List of Galaxies for Gravitational Wave Searches White D.J., Daw E.J., Dhillon V.S. <Class. Quantum Grav. 28, 085016 (2011); arXiv:1103.0695>
ADC_Keywords: Galaxy catalogs Abstract: We present a list of galaxies within 100Mpc, which we call the Gravitational Wave Galaxy Catalogue (GWGC), that is currently being used in follow-up searches of electromagnetic counterparts from gravitational wave searches. Due to the time constraints of rapid follow-up, a locally available catalogue of reduced, homogenized data is required. To achieve this we used four existing catalogues: an updated version of the Tully Nearby Galaxy Catalog (cat. VII/145), 145 the Catalog of Neighboring Galaxies (Karachentsev et al. 2004, Cat. J/AJ/127/2031), the V8k catalogue (Tully et al. 2009AJ....138..323T, http://edd.ifa.hawaii.edu/) and HyperLEDA (http://leda.univ-lyon1.fr/). The GWGC contains information on sky position, distance, blue magnitude, major and minor diameters, position angle, and galaxy type for 53,255 galaxies. Errors on these quantities are either taken directly from the literature or estimated based on our understanding of the uncertainties associated with the measurement method. By using the PGC numbering system developed for HyperLEDA, the catalogue has a reduced level of degeneracies compared to catalogues with a similar purpose and is easily updated. We also include 150 Milky Way globular clusters. Finally, we compare the GWGC to previously used catalogues, and find the GWGC to be more complete within 100 Mpc due to our use of more up-to-date input catalogues and the fact that we have not made a blue luminosity cut.
