Description
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 features 1000 tons of liquid
scintillator and is sensitive with full efficiency to core-collapse and failed
supernovae occurring in the Galaxy through neutrino burst detection.
In this communication we review methods for the neutrino burst search and we update
the results of the second run, lasting from 2014, January 1$^{st}$ to 2025, Jan
16$^{th}$ for a total live time of $4013$ days.
In the lack of a positive observation in this dataset and in previously published
results since 1992 for a total live time of $11347$ days, we set an upper limit to
the rate of core-collapse and failed supernovae in the Galaxy of $0.07\ $year$^{-1}$
at 90% c.l. .
