We investigate the effects of massive gravitons on the rotation curves of the Milky Way, spiral galaxies, and low surface… Expand G [4, 5, 6, 7]. Standard models for neutron stars traditionally assume thatthese objects are perfect spheres whose properties are… Expand We obtain the equations of motions of the f(T) theory considering the Lemaître-Tolman-Bondi’s metric for a set of diagonal and… Expand We investigate the properties of relativistic star spheres made of an electrically charged incompressible fluid, generalizing… Expand We explore a class of compact charged spheres made of a charged perfect fluid with a polytropic equation of state. The charge… Expand The notion of thermal time has been introduced as a possible basis for a fully general-relativistic thermodynamics. Here we study… Expand We study the kinematic Sunyaev-Zel'dovich (kSZ) effect in a Lemȋtre-Tolman-Bondi (LTB) universe model whose distance-redshift… Expand Abstract In this Letter we investigate the minimal conditions under which the creation of our universe might arise due to a… Expand Abstract Abstract. This experiment was designed to quantify the motivation to show socially facilitated behaviour, by equating… Expand Thermodynamic equilibrium of a self-gravitating perfect fluid for a spherically symmetric system containing a black hole of mass… Expand
