Late-time Observations of the New Class of Relativistic Tidal Disruption Flares
Abstract
The high-energy transient Sw J1644+57, discovered by the Swift satellite in 2011, has been suggested to result from the tidal disruption of a star by a super-massive black hole. Aside from the thermal emission associated with the accretion disk formed by the returning stellar debris, the outburst unambiguously triggered the formation of a relativistic jet, leading to luminous X-ray emission and a long-lived radio transient. Shortly thereafter, another high-energy transient source, Sw J2058+05, was also suggested as a possible member of this new class of relativistic outbursts. Here we present late-time multi-wavelength observations of both of these sources, as part of a program to track their long-term behavior and better understand the ultimate processes responsible for these remarkable transients.
