Description

For nearly a century, Einstein’s theory of gravity has been the standard theory for describing gravitational phenomena in our universe. Along with its successes, there are some questions for which it does not provide a satisfactory answer. This has led to proposals that modify or supersede Einstein’s theory, and testing these theories against data, especially in the strong-field regime, has emerged as a new paradigm in physics in recent years. Along with the completely new avenue of gravitational waves, new and improved techniques based on electromagnetic waves are being used to test GR ever more stringently. As the realm beyond GR is unknown, a popular approach is to look for theory-agnostic deviations from GR/predictions of GR. In my poster, I describe how I have used gravitational waves, x-rays, and black hole shadows to constraints on some of these theory-agnostic deviations.
