Dinámica y distribución de los vacios del universo
(2018-12)
En este trabajo de tesis realizamos un estudio estadístico de la dinámica y la distribución espacial de las mayores regiones del Universo desprovistas de galaxias brillantes, denominadas vacíos, utilizando datos observacionales ...
Cúmulos de galaxias : propiedades de galaxias y subsistemas
(2008-03)
En la presente tesis se llevó a cabo un estudio estadístico sobre la dependencia de las propiedades de las galaxias brillantes y sus subsistemas como función de los parámetros globales de los cúmulos masivos de galaxias, ...
A z = 0.9 Supercluster of X-Ray Luminous, Optically Selected, Massive Galaxy Clusters
(2008)
We report the discovery of a compact supercluster structure at z = 0.9. The structure comprises three optically selected clusters, all of which are detected in X-rays and spectroscopically confirmed to lie at the same ...
Morphological properties of superclusters of galaxies
(WILEY-BLACKWELL, 2011)
We studied superclusters of galaxies in a volume-limited sample extracted from the Sloan Digital Sky Survey Data Release 7 and from mock catalogues based on a semi-analytical model of galaxy evolution in the Millennium ...
Shapley Supercluster Survey: ram-pressure stripping versus tidal interactions in the Shapley supercluster
(2016)
We present two new examples of galaxies undergoing transformation in the Shapley supercluster core. These low-mass galaxies are members of the two clusters SC 1329-313 and SC 1327-312 z similar to 0.049). Integral-field ...
Distances from stellar kinematics for peculiar Virgo Cluster spiral galaxies
(UNIV CHICAGO PRESS, 2008-08-10)
We present distance estimates for 11 peculiar Virgo Cluster spiral galaxies based on measurements of the stellar kinematics of their central 2 kpc. Stellar circular velocities were obtained using two- integral dynamical ...
