Title: Dwarf Hosts of Low-z Supernovae

Abstract: Hostless supernovae (SNe), or SNe in dwarf galaxies, may serve as excellent beacons for probing the spatial density of dwarf galaxies (M < 10^8 Msun), which themselves are scarcely detected beyond only a few Mpc. Depending on the assumed model for the stellar-mass to halo mass relation for these galaxies, LSST might see 1000s of SNe (of all types) from dwarf galaxies alone. Conversely, one can take the measured rates of these SNe and test the model predictions for the density of dwarf galaxies in the local universe. Current ”all-sky” surveys, like PanSTARRS and ASAS-SN, are now finding hostless SNe at a number sufficient to measure their rate. What is missing is the appropriate weighting of their host luminosities. Here we seek to continue a successful program to recover the host luminosities of these 'hostless' SNe, to z=0.15, to use their rate to constrain the faint-end slope of the low-z galaxy luminosity function.
