WELCOME TO BLAST!

A DJANGO WEB APP FOR THE AUTOMATIC REAL-TIME CHARACTERIZATION OF TRANSIENT HOST
GALAXIES

Search the blast database Read the docs

The host galaxies of astrophysical transients play a key role in our
understanding of their progenitor systems and the use of Type Ia supernovae as
standardizable candles for cosmology. However, fully characterizing host galaxy
environments requires a high-statistics, unbiased, multiwavelength dataset,
preferably with 1-2 kpc resolution. Current analyses are limited by sample sizes
of anywhere from ~10-200 SNe, predominantly optical host observations, and
observational biases such as selecting from surveys that search for SNe within a
pre-selected a set of galaxies.

Blast is a public web application built to find a transinet's host galaxy,
identify the available archival data, and measure the resulting host galaxy star
formation rates, masses, and stellar ages - for every new transient reported to
the IAU in real-time after the transient is announced. This information is not
provided by any existing transient broker service.
