SN rates and luminosity functions from ASAS-SN II
Listed in IVOA Registry (Virtual Observatory)
The volumetric rates and luminosity functions (LFs) of core-collapse supernovae (ccSN) and their subtypes are important for understanding the cosmic history of star formation and the buildup of ccSNe products.
Description
To estimate these rates, we use data of nearby ccSNe discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) from 2014-2017, when all observations were made in the V-band. The sample is composed of 174 discovered or recovered events, with high spectroscopic completeness from followup observations.
This allows us to obtain a statistically precise and systematically robust estimate of nearby rates for ccSNe and their subtypes. The volumetric rates are estimated by correcting the observed number of events for the survey completeness, which was estimated through injection recovery simulations using ccSN light curves. We find a total volumetric rate for ccSNe of 7.0x10^-5^yr^-1^Mpc^-3^*h^3^, at a median redshift of 0.0149, for absolute magnitudes at peak M_V,peak_<=-14mag.

This result is in agreement with previous local volumetric rates. We obtain volumetric rates for the different ccSN subtypes (II, IIn, IIb, Ib, Ic, Ibn, and Ic-BL), and find that the relative fractions of Type II, stripped-envelope, and interacting ccSNe are 63.2%, 32.3%, and 4.4%, respectively. We also estimate a volumetric rate for superluminous SNe of 1.5yr^-1^Gpc^-3^*h^3^, corresponding to a fraction of 0.002% of the total ccSN rate.We produce intrinsic V-band luminosity functions of ccSNe and their subtypes, and show that ccSN rates steadily decline for increasing luminosities.
We further investigate the specific ccSN rate as a function of their host galaxy stellar mass, and find that the rate decreases with increasing stellar mass, with significantly higher rates at lower mass galaxies (logM*<9.0M_{sun}_).
