Description
SNEWS is a cooperative effort between the world's neutrino detectors to
spread the news that a star in our galaxy has just experienced a
core-collapse event and is about to become a supernova. This project
exploits the ~hours time difference between neutrinos promptly escaping
the nascent supernova and photons which originate when the shock wave
breaks through the stellar photosphere. This will give the world a
chance to get ready to observe such an exciting event at the earliest
possible time. Although there has not recently been a Galactic
supernova, SNEWS has been functioning as a coincidence trigger between
experiments for two decades now. With great advances in other forms of
multi-messenger astronomy in the past few years, SNEWS is being upgraded
to adapt to this improved environment. Progress on implementing ideas to
maximize the science output of this new "SNEWS2.0" will be presented.
