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, 1000 tons of liquid scintillator, is sensitive to core-collapse supernovae via neutrino burst detection with 100\% efficiency in the Milky Way.
In this paper we discuss methods of the neutrino burst search and we present the results of the last run, lasting from 2014, January 1$^{st}$ to 2021, Jan 4$^{th}$ for a total live time of $2504$ days.
In the lack of a positive observation in this dataset and including all previously published results since 1992 for a total lifetime of $9839$ days, the upper limit on the rate of core collapse and failed supernova explosions out to distances of 25 kpc is $0.085$ year$^{-1}$ at 90\% c.l. .
