The IceCube Neutrino Observatory has established the existence of a high-energy all-sky neutrino flux of astrophysical origin. This discovery was made using events interacting with…
A Family Tree of Optical Transients from Narrow-Line Seyfert 1 Galaxies
Sara Frederick, Suvi Gezari, Matthew J. Graham +17
The Zwicky Transient Facility (ZTF) has discovered five new events belonging to an emerging class of AGN undergoing smooth flares with large amplitudes and rapid rise times. This s…
