Gravitational waves in theories modified gravity
Since the first direct detection of gravitational waves (GWs) their study became one of the most active and exciting research directions in theoretical physics and astrophysics. New GW observatories are being planned to be built that will improve the sensitivity and extend the frequency range over the currently available instruments.
GW observations allow us to test the laws of gravity in regimes that have not been tested before. With this new tool we can constrain possible deviations from General Relativity (GR) and rule out many modified gravity theories.
In this PhD program we will study how to interpret GWs and other observables and their measurements within the framework of various modified gravity theories. We will investigate possible GW generation mechanisms and their differences with respect to GR. Similar methods will be applied to study cosmological and astrophysical phenomena, including recently detected various anomalies.
