dc.description.abstract |
Although Einstein’s theory of gravity has already passed many tests in the last
century, it is still one of the most discussed theories in physics. Its strong-field
regime can only be accessed through the study of ultra-compact objects like,
e.g., black holes. In this report, we propose using black holes with metrics that
deviate from the standard Kerr solution in order to probe the strong-field regime
of gravity. For measuring the effects induced by the deviation, we study tidal
disruption events from which large amounts of energy in electromagnetic and
gravitational radiation are released. We developed an approach to implement
arbitrary metrics that are not solutions of Einstein’s equations into the framework
of a fully general relativistic code. The results from our numerical simulations can
then be compared with data from actual observed events and place constraints on
the metric deviation parameters, hence assessing the validity of general relativity
in gravity’s very extremes. |
