Searching for thermal electrons in the relativistic tidal disruption event Swift J1644+57
Tidal Disruption Events (TDE) occur when a star travels too close to a supermassive black hole. During a TDE, the star is ripped apart due to the gravitational pull of the black hole and produces a bright multi-wavelength radiation that evolves over a timescale of years. The first observation of a TDE was made in the 1990s, and since the substantial strides have been made in our understanding. Contrary to popular believe, if is very hard to funnel material into a black hole and so when a star is disrupted the black hole ejects a lot of the stellar material at velocities close to the speed of light. As the ejected material travels away from the supermassive black holes it produces radio light. In the proposed project, the student will use observations of a TDE discovered in made at radio frequencies studying the content of the ejected material and to understand the impact that a TDE can have on the environment surrounding the supermassive black hole.
