Title: Late-time X-ray and Radio Observations of the Unique Relativistic TDE Sw 1644+57

PI Name: Tarraneh Eftekhari

Transient accretion onto a supermassive black hole due to the tidal disruption of a star provides a unique opportunity to observe the birth and evolution of relativistic jets. The discovery of the first such event by Swift in 2011 has opened a new window into these events. Previous X-ray and radio observations have traced the evolution of the jet and helped to characterize the ambient medium surrounding a previously dormant supermassive black hole. In this Chandra proposal, we seek to track the continued dynamical evolution of the jet into the non-relativistic regime. Joint X-ray and radio observations will probe the properties of the outflow nearly 7 years later and help to constrain the density profile around the black hole to extended radii.
