Abstract
The Large Volume Detector (LVD) at the INFN Gran Sasso National
Laboratory, Italy, is a neutrino observatory designed
to study low energy neutrinos from gravitational stellar
collapses. The detector, 1 kton of liquid scintillator, is sensitive to core-collapse supernovae via neutrino
burst detection with 100% efficiency over the Galaxy.
In this contribution we summarize the results of the last run, lasting from 2014, January
1st to 2021, May 5th for a total live time of 2672 days.
In the lack of a positive observation in this data set and including all previously published results since 1992 for a total live-time of 10007
days, the upper limit on the rate of core collapse and
failed supernova explosions out to distances of 25 kpc is 0.08 year−1 at 90% c.l..
