The Fate of Dwarf Galaxies in Clusters and the Origin of Intracluster Stars
Cosmology—galaxies clusters dwarfs interactions—methods numerical
2010/9/15
The main goal of this paper is to compare the relative importance of destruction by tides vs. destruction by mergers, in order to assess if tidal destruction of galaxies in clusters is a viable scenar...
A COMPARISON OF TWO MASS DISTRIBUTIONS APPLICABLE TO GLOBULAR CLUSTERS AND DWARF GALAXIES
globular clusters general-Galaxy halo-Galaxies dwarf
2009/3/6
A particular case of mass distribution in stellar systems, already
described in the literature, is compared to the King model of mass distribution. For
the cases which would correspond to the descri...
GLOBULAR CLUSTERS AND PLANETARY NEBULAE KINEMATICS AND X–RAY EMISSION IN THE EARLY–TYPE GALAXY NGC 5128
Galaxies kinematics and dynamics-Galaxies elliptical and lenticular, cD-Galaxies structure-dark matter-Galaxies individual (NGC5128)
2009/2/18
The estimates of the mass of the galaxy NGC 5128 based on the
di erent mass tracers, globular clusters (GCs) and planetary nebulae (PNe), are
presented. These estimates are compared with the estimat...
GRADIENT OF MEAN MASS OF A STAR IN THE FIELD OF GLOBULAR CLUSTERS
globular clusters general-Stars fundamental parameters (masses)
2009/2/16
Based on the relevant available data, the distributions of masses
and apparent magnitudes of stars belonging to globular star clusters are simulated.
The simulations are aimed at examining the in°ue...
ON THE DENSITY AND SURFACE BRIGHTNESS PROFILES IN GLOBULAR STAR CLUSTERS
globular clusters general
2009/2/13
A model of mass distribution, applicable to globular star clusters
and proposed earlier, is reconsidered. It is shown that it can be related to the
well-known Plummer-Schuster formula, and the equat...
Using X-ray observation we have obtained the deprojected gas density and temperature profiles for a sample of cluster of galaxies. We show that cool-core clusters, which are expected to be the largest...
Light on Dark Matter: Gravitational Lensing by Galaxy Clusters
Dark Matter Gravitational Lensing Galaxy Clusters
2010/10/18
I discuss the use the weak gravitational lensing effect to study the mass distribution and dynamical state of a sample of 24 X-ray luminous clusters of galaxies. By comparing the mass and light distri...
