Avanço do periastro e deflexão da luz no campo gravitacional de estrelas e buracos negros carregados e em rotação
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2007-03-08)
In the present study it is obtained analytic expressions to the periastron advance and light bending in the gravitational field of rotating and electrically charged black holes. First it is made a historical review emphasizing ...
Swift J1357.2-0933: a massive black hole in the Galactic thick disc
(OXFORD UNIV PRESS, 2015)
Swift J1357.2-0933 is one of the shortest orbital period black hole X-ray transients. It exhibited deep optical dips together with an extremely broad Ha line during outburst. We present 10.4-m Gran Telescopio Canarias (GTC) ...
Supermassive black holes in the EAGLE Universe. Revealing the observables of their growth
(2016)
We investigate the evolution of supermassive black holes in the 'Evolution and Assembly of GaLaxies and their Environments' (EAGLE) cosmological hydrodynamic simulations. The largest of the EAGLE volumes covers a (100 cMpc) ...

Equatorial outflows driven by jets in Population III microquasars
(Springer, 2021-01)
Binary systems of Population III can evolve to microquasars when one of the stars collapses into a black hole. When the compact object accretes matter at a rate greater than the Eddington rate, powerful jets and winds ...
