Cosmological and astrophysical applications of modified theories of gravity
João Luís Rosa
In this work, we study cosmological and astrophysical applications of the recently proposed generalized hybrid metric-Palatini gravity theory, which combines features of both the m…
Cosmological phase space of generalized hybrid metric-Palatini theories of gravity
João L. Rosa, Sante Carloni, José P. S. Lemos
Using a dynamical system approach we study the cosmological phase space of the generalized hybrid metric-Palatini gravity theory, characterized by the function $f\left(R,\mathcal R…
On Derrick's theorem in curved spacetime
Sante Carloni, João Luís Rosa
We extend Derrick's theorem to the case of a generic irrotational curved spacetime adopting a strategy similar to the original proof. We show that a static relativistic star made o…
Ultralight boson cloud depletion in binary systems
Emanuele Berti, Richard Brito, Caio F. B. Macedo +2
Ultralight scalars can extract rotational energy from astrophysical black holes through superradiant instabilities, forming macroscopic boson clouds. This process is most efficient…
