Microquasars
(Societa Astronomica Italiana, 2011-01)
Microquasars are compact objects (stellar-mass black holes and neutron stars) that mimic, on a smaller scale, many of the phenomena seen in quasars. Their discovery provided new insights into the physics of relativistic ...
Termodinâmica de buracos negros
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2021-04-13)
The objective of this work is to construct and present the so-called black hole thermodynamics. First, the elements of general relativity necessary for the characterization of black holes are exposed, and then the four ...
Falling into a Schwarzschild black holeCayendo hacia un agujero negro de Schwarzschild

Collisions of spinning massive particles in a schwarzschild background
(2016)
It is known that the center-of-mass energy of the collision of two massive particles following geodesics around a black hole presents a maximum. The maximum energy increases when the black hole is endowed with spin, and ...
Regular Rotating Black Holes And The Weak Energy Condition

Modos quase-normais de buracos negros plano-simétricos anti-de sitter em d dimensões
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2007-08-22)
Quasinormal modes of plane-symmetric anti-de Sitter (AdS) black holes in d spacetime dimensions are investigated. Following the gauge invariant prescription developed by Kodama, Ishibashi and Seto (2000), fundamental ...
Measuring the Spin of Black Holes in Binary Systems Using Gravitational Waves
(Amer Physical Soc, 2014)
Probing the regular nature of the spacetime by direct measurement of black hole properties
(2015-09-02)
In the following years Very Long Baseline Interferometry (VLBI) facilities will be able to directly image the accretion flow around the supermassive black hole candidate at the center of the Milky Way, Sgr A*. They will ...
