Type la supernova rate at a redshift of ∼0.1

Abstract:

We present the type la rate measurement based on two EROS supernova search campaigns (in 1999 and 2000). Sixteen supernovae identified as type la were discovered. The measurement of the detection efficiency, using a Monte Carlo simulation, provides the type la supernova explosion rate at a redshift ∼0.13. The result is 0.125 -0.034-0.028+0.044+0.028 h 702 SNu where 1 SNu= 1 SN / 10 10 L ⊙B / century. This value is compatible with the previous EROS measurement (Hardin et al. 2000), done with a...
