TL;DR
GLADE is a comprehensive galaxy catalogue designed to aid multi-messenger astrophysics by identifying host candidates for gravitational-wave events and electromagnetic transients, supporting follow-up observations and cosmological studies.
Contribution
It provides a new, complete all-sky galaxy catalogue combining multiple data sources, optimized for local universe gravitational-wave and electromagnetic transient follow-ups.
Findings
Complete up to 37 Mpc in B-band luminosity
Includes all brightest galaxies within 91 Mpc
Useful for estimating binary neutron star merger host completeness
Abstract
We introduce a value-added full-sky catalogue of galaxies, named as Galaxy List for the Advanced Detector Era, or GLADE. The purpose of this catalogue is to (i) help identifications of host candidates for gravitational-wave events, (ii) support target selections for electromagnetic follow-up observations of gravitational-wave candidates, (iii) provide input data on the matter distribution of the local universe for astrophysical or cosmological simulations, and (iv) help identifications of host candidates for poorly localised electromagnetic transients, such as gamma-ray bursts observed with the InterPlanetary Network. Both being potential hosts of astrophysical sources of gravitational waves, GLADE includes inactive and active galaxies as well. GLADE was constructed by cross-matching and combining data from five separate (but not independent) astronomical catalogues: GWGC, 2MPZ, 2MASS…
