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 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.
