    • On the possibility of ultracompact stars in semiclassical gravity 

      Volkmer, Guilherme Lorenzatto (2022) [Tese]
      In broad terms, compact stars are astrophysical objects that are stabilized by the pressure of degenerate matter. Driven by the rising gravitational-wave era in astronomy we can find a renewed interest in theoretical ...

    • Rotational compact stars in 5-dimensional brane-world gravity 

      Vanazzi, João Vítor Batista (2019) [Dissertação]
      We apply Hartle’s perturbative method for slow rotational stars in 5D Brane-World Gravity theory with Randall-Sundrum geometry of the second kind (RS2). We obtain the modified frame-dragging, monopole and quadrupole ...

    • Testing general relativity at galactic scales 

      Carneiro, Carlos Roberto de Melo (2021) [Dissertação]
      General Relativity (GR) has been successfully tested in Solar system scales. However, for galactic scales, this theory has been poorly tested. Moreover, several galaxy data analysis depend on the value of the Hubble constant ...
