Beschreibungen/Notizen

• We present the type Ia rate measurement based on two EROS supernova search campaigns (in 1999 and 2000). Sixteen supernovae identified as type Ia were discovered. The measurement of the detection efficiency, using a Monte Carlo simulation, provides the type Ia supernova explosion rate at a redshift ~0.13. The result is $0.125^{+0.044+0.028}_{-0.034-0.028}\ h_{70}^2$ SNu where 1 SNu = 1 SN / $10^{10}\ {L}_{\odot}^B$ / century. This value is compatible with the previous EROS measurement [CITE], done with a much smaller sample, at a similar redshift. Comparison with other values at different redshifts suggests an evolution of the type Ia supernova rate.
