One of the main sceintific goals of ASAS-SN is to compile an unbiased sample of bright, local supernovae. We have been very succesful in that goal, including finding many supernovae in dwarf galaxies, possibly including even some ``hostless'' events. The diversity of supernova hosts in nicely illustrated in the figure above, where for a sample of 30 Type Ia explosions discovered by ASAS-SN we show SDSS image for the host galaxy, sorted from least luminous in the top left to most luminous (using 2MASS) in the bottom right. Distances to the hosts and the SN names are given in each sub-panel. The images are centered on the SN position, and it is easy to immediately see that our discoveries span a wide range of separations from the host nuclei, as well as host luminosities, colors, and morphologies.

Why do we care? Our group has published a number of papers exploring how properties of different kinds of supernovae and also gamma-ray burst depend on their hosts, and obtaining unbiased samples of cosmic explosions is crucial in these studies.
