Gravitational instability of a nonrotating galaxy
Physical Review Special Topics. Accelerators and Beams, 2009 Gravitational instability of the distribution of stars in a galaxy is a well-known phenomenon in astrophysics. This report is an attempt to analyze this phenomenon by applying standard tools developed in accelerator physics.

Origin of very high energy emission in galaxy clusters
EPJ Web of Conferences, 2017 The Perseus cluster of galaxies with the central galaxy NGC 1275 is ideally suitable for studying both the physics of relativistic jets from Active Galactic Nuclei and for revealing the feedback role of the central galaxy.

The Identification of Physical Close Galaxy Pairs [PDF]
The Astronomical Journal, 2007 A classification scheme for close pairs of galaxies is proposed. The scheme is motivated by the fact that the majority of apparent close pairs are in fact wide pairs in three-dimensional space. This is demonstrated by means of numerical simulations of random samples of binary galaxies and the scrutiny of the resulting projected and spatial separation ...

Extragalactic and cosmological tests of gravity theories with additional scalar or vector fields [PDF]
, 2011 Despite the many successes of the current standard model of cosmology on the largest physical scales, it relies on two phenomenologically motivated constituents, cold dark matter and dark energy, which account for approximately 95% of the energy-matter ...
