Physics

Scientific paper

We propose for rapid follow-up Chandra TOO ACIS-S observations and HST/COS NUV imaging and FUV low-resolution spectroscopy of 5 flares from the tidal disruption of stars by supermassive black holes discovered in the Pan-STARRS1 Medium Deep Survey. With TOO observations obtained within a month of the peak of the flare, and 5 months later, we aim to 1) constrain the flare's broadband SED and bolometric luminosity, 2) follow the decay of the flare and look for spectral evolution, and 3) place strong limits on the presence of a persistent AGN nucleus. Tidal disruption events provide a cosmic laboratory to study the physics of accretion onto black holes, and are a unique probe of the mass of black holes in the nuclei of distant galaxies.
