Today in MNRAS, I worked on a paper describing the resaults of the ASAS-SN neutrino follow-up program.
ASAS-SN has performed automated follow-up of 56 different neutrino alerts from the IceCube Neutrino Observatory, making it the largest optical follow-up program to date.
No new counterparts were identified, but we were able to set limits on the optical emission from the neutrino sources. These limits many exclude the existence of a population of very bright neutrino sources.
The known associations of TDE AT2019dsg and blazar TXS 0506+056 were also recovered by ASAS-SN.
