TL;DR
This study analyzes 21 years of data from the Large Volume Detector to set upper limits on the rate of core-collapse supernovae in our galaxy, finding no neutrino burst evidence over that period.
Contribution
It provides the first long-term limit on galactic supernova rates based on neutrino detection data from the LVD.
Findings
No neutrino signals detected over 21 years
Upper limit of 0.114 supernovae per year within 25 kpc
Constraints on supernova occurrence rates in the galaxy
Abstract
The Large Volume Detector (LVD) has been continuously taking data since 1992 at the INFN Gran Sasso National Laboratory. LVD is sensitive to neutrino bursts from gravitational stellar collapses with full detection probability over the Galaxy. We have searched for neutrino bursts in LVD data taken in 7335 days of operation. No evidence of neutrino signals has been found between June 1992 and December 2013. The 90% C.L. upper limit on the rate of core-collapse and failed supernova explosions out to distances of 25 kpc is found to be 0.114/y.
