We report a comprehensive statistical analysis of the observational data of the cosmic evolution of supernova ( SN ) rate density , to derive constraints on cosmic star formation history and the nature of type Ia supernova ( SN Ia ) progenitor .
We use all available information of magnitude , SN type , and redshift information of both type Ia and core-collapse ( CC ) SNe in GOODS and SDF , as well as SN Ia rate densities reported in the literature .
Furthermore , we also add 157 SN candidates in the past Subaru/Suprime-Cam data that are newly reported here , to increase the statistics .
We find that the current data set of SN rate density evolution already gives a meaningful constraint on the evolution of the cosmic star formation rate ( SFR ) at z \lesssim 1 , though strong constraints can not be derived for the delay time distribution ( DTD ) of SNe Ia .
We derive a constraint of \alpha \sim 3–4 [ the evolutionary index of SFR density \propto ( 1 + z ) ^ { \alpha } at z \lesssim 1 ] with an evidence for a significant evolution of mean extinction of CC SNe [ E ( B - V ) \sim 0.5 at z \sim 0.5 compared with \sim 0.2 at z = 0 ] , which does not change significantly within a reasonable range of various DTD models .
This result is nicely consistent with the systematic trend of \alpha estimates based on galactic SFR indicators in different wavelengths ( ultraviolet , H \alpha , and infrared ) , indicating that there is a strong evolution in mean extinction of star forming regions in galaxies at relatively low redshift range of z \lesssim 0.5 .
These results are obtained by a method that is completely independent of galaxy surveys , and especially , there is no detection limit about the host galaxy luminosity in our analysis , giving a strong constraint on the star formation activity in high- z dwarf galaxies or intergalactic space .
