SNEWS has developed software for our supernova neutrino searches. SNEWPY is an open-source software package which bridges the gap between supernova simulations and the corresponding signals in neutrino detectors which will help make comparison between theory and observation. The output from SNEWPY may be used by an event generator such as sntools or an event rate calculator such as SNOwGLoBES. To determine if a supernova alert should be issued, SNEWS developed an alert application that extends the SCiMMA hop-client. This application monitors the observations published by detectors in the SNEWS network, and can optionally send alerts upon the detection of a potential supernova. Following observations published by detectors, SNEWPDAG is a calculation engine to create a skymap of the possible location of the supernova to pass to professional and amateur astronomers around the world.
The next Galactic core-collapse event will allow for complete multi-messenger observations of the supernova across the electromagnetic spectrum, in gravitational waves, and in neutrinos. While SNEWS will observe the neutrinos from the event, other collaborations can help with other observations. LIGO and VIRGO are gravitational wave observatories. REFITT coordinates professional and amateur astronomers around the world, including members of AAVSO, to perform time-sensitive observations of astronomical transients. A list of the most recent supernovae in other galaxies can be found at Latest Supernovae. Hopefully we can observe a supernovae in our galaxy within our lifetimes!
