Generalized theory of clustering of extended galaxies with core halos

Physics of the Dark Universe, 2021
Abstract We discuss the clustering of core halo-galaxies of radius predicted by gravitational lensing. We appeal to a blend of recent (1) mathematical results and (2) statistical mechanics techniques. The exact configurational integrals of extended galaxies is evaluated together with the pertinent partition functions, the corresponding thermodynamics,

Second-generation galaxies in merging clusters?

Astronomical & Astrophysical Transactions, 2004
We consider gas-dynamics phenomena in merging clusters of galaxies. According to X-ray observations, merger shocks involve considerable baryonic masses and compress them into large-scale gaseous layers. The internal structure of the layers includes vorticity and magnetic fields generated in the process of the layer formation and evolution.

Clusters and Voids in General Galaxy Field

Symposium - International Astronomical Union, 1996
In our previous works (Anosova 1987, Anosova, Iyer, Varma 1994), we developed a new method for determination of the structure of a clustered distribution. In this work, we apply this method studying the observed distribution of galaxies in the Universe.

Vortex Generation by Shock-Bubble Interaction in Galaxy Clusters

2015
Fluid mechanics is at the heart of almost all astronomical research. In many cases, the conditions in astrophysical systems are such that supersonic flows are common. As a result, the most energetic phenomena in astronomy all involve some form of shock physics, often relativistic.

Next-Generation Images of Galaxy Clusters at Millimeter Wavelengths

Galaxy clusters are the largest and most massive objects in the universe. Observing and studying them unlocks answers to broad cosmological questions, such as the matter content and its distribution in the universe, as well as more specific astrophysical topics regarding the nature of physics within the intracluster medium (ICM).

The Next Generation Virgo Cluster Survey (NGVS). II. A Catalog of Galaxies in the Virgo Cluster

The Next Generation Virgo Cluster Survey (NGVS) is a deep, high resolution imaging campaign that used the 1 deg$^2$ MegaCam instrument on the Canada-France-Hawaii Telescope to carry out a comprehensive optical survey of the Virgo cluster, from its core to its virial radius.
