N-Body Simulations of Primordial Star Clusters: Formation Pathway for Intermediate Mass Black Holes
(2018)
In this work we show how could have been formed intermediate mass black holes in
the early Universe through stellar collisions between the first stars of the Universe that
formed part of dense stellar clusters. Our work ...
The runaway black hole GRO J1655-40
(EDP Sciences, 2002-11)
We have used the Hubble Space Telescope to measure the motion in the sky and compute the galactocentric orbit of the black hole X-ray binary GRO J1655-40. The system moves with a runaway space velocity of 112+/- 18 km s-1 ...

Magnetised accretion discs in Kerr spacetimes
(EDP Sciences, 2015-02)
Context. Observational data from X-ray binary systems provide strong evidence of astronomical objects that are too massive and compact to be explained as neutron or hybrid stars. When these systems are in the thermal ...
Supermassive black hole growth in starburst galaxies over cosmic time: Constraints from the deepest chandra fields
(2011)
We present an analysis of deep multiwavelength data for z ~ 0.3-3 starburst galaxies selected by their 70 um emission in the Extended-Chandra Deep Field-South and Extended Groth Strip. We identify active galactic nuclei ...
Stability of circular orbits of particles moving around black holes surrounded by axially symmetric structures
(American Physical SocCollege PkEUA, 2003)
BLACK HOLE MASSES AND HOST GALAXY EVOLUTION OF RADIO-LOUD ACTIVE GALACTIC NUCLEI
(2005-10-01)
We report stellar velocity dispersion measurements for a sample of 28 active galactic nucleus (AGN) host
galaxies, including our previous work. Using the mass-dispersion (M.- ) and the fundamental plane relations, ...
Observadores relativistas y termodinámica del colapso gravitacional de cascarones negros
(Universidad Nacional de ColombiaBogotá - Ciencias - Doctorado en Ciencias - FísicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022)
Se estudia el colapso de un cascarón de polvo delgado desde dos enfoques diferentes: clásico y semiclásico. En el enfoque clásico se identifican superficies críticas cuyas coordenadas de tiempo y espacio intercambian sus ...
Self-gravitating black hole scalar wigs
(American Physical Society, 2017-07-26)
It has long been known that no static, spherically symmetric, asymptotically flat Klein-Gordon scalar field configuration surrounding a nonrotating black hole can exist in general relativity. In a series of previous papers, ...
