Abstract
In this talk I will focus on some modifications of General Relativity, particularly on the so-called f(R) gravities within the Palatini formalism.

Screened modified gravity is inherently elusive: screening mechanisms suppress the propagation of additional gravitational degrees of freedom in typical astrophysical scenarios, allowing these theories to avoid constraints coming from weak field observations.
Gravitational Wave Observations of Black Hole and Neutron Star Mergers

Following the first observation of gravitational waves from merging black holes in 2015, we have now observed gravitational wave signals from over 50 binary mergers. In this talk, I will review the most recent observations from the first half of the third LIGO and Virgo observing run. I will highlight some of the most novel events and will discuss the impacts of these observ
