Efecto de lente gravitacional unificado: una aproximación a la reconstrucción del perfil de masa de un cúmulo galáctico
(Bogotá - Ciencias - Maestría en Ciencias - AstronomíaUniversidad Nacional de Colombia - Sede Bogotá, 2020-10-28)
In this work, we present the description, implementation, and application of a free-form reconstruction method that makes use of the gravitational lensing effect to produce an estimation of the mass profile of a galaxy ...
A model for the non-thermal emission of the very massive colliding-wind binary HD 93129A
(EDP Sciences, 2016-07)
Context. Recently, the colliding-wind region of the binary stellar system HD 93129A was resolved for the first time using Very Large Baseline Interferometry. This system, one of the most massive known binaries in our Galaxy, ...
A spectroscopic study of the open cluster NGC 6475 (M 7). Chemical abundances from stars in the range Teff = 4500-10 000 K
(2009)
Aims. Clusters of stars are key objects for studying the dynamical and chemical evolution of the Galaxy and its neighbors, and are the most important laboratories to test the theory of stellar evolution. In particular, ...

VVV DR1: The first data release of the Milky Way bulge and southern plane from the near-infrared ESO public survey VISTA variables in the Vía Láctea
(Edp Sciences, 2012-01)
Context. The ESO public survey VISTA variables in the Vía Láctea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for about five years. Aims. We ...
