Описание: Many applications in time-domain and multi-messenger astronomy rely on wide galaxy catalogs with reliable distances and stellar masses, yet existing resources are often incomplete beyond ~100 Mpc or lack uniform measurements. REGALADE was built to address this, an all-sky catalog of nearly 80 million galaxies out to 2000 Mpc. It combines major catalogs and deep surveys, integrates spectroscopic and aggregated photometric redshifts, removes stellar contaminants with Gaia, and provides stellar masses and sizes for most galaxies. Designed for transient and GW follow-up, it improves host identification and significantly increases the number of known transient hosts. REGALADE will be released openly to support community science with Rubin/LSST and beyond.
