Supernova rates from the Southern inTermediate Redshift ESO Supernova Search (STRESS)

Understand

To measure the supernova (SN) rates at intermediate redshift we performed the Southern inTermediate Redshift ESO Supernova Search (STRESS).

• Unlike most of the current high redshift SN searches, this survey was specifically designed to estimate the rate for both type Ia and core collapse (CC) SNe.
• We counted the SNe discovered in a selected galaxy sample measuring SN rate per unit blue band luminosity.
• Our analysis is based on a sample of ~43000 galaxies and on 25 spectroscopically confirmed SNe plus 64 selected SN candidates.
