Starbursts in multiple galaxy mergers [PDF]
The Astrophysical Journal, 2000 We numerically investigate stellar and gaseous dynamical evolution of mergers between five identical late-type disk galaxies with the special emphasis on star formation history and chemical evolution of multiple galaxy mergers.

Galaxy mergers in a fractal cosmology
European Physical Journal C: Particles and FieldsThis work discusses the influence of galaxy mergers in the evolution of a parabolic Lemaître–Tolman–Bondi (LTB) cosmology with simultaneous big bang endowed with two consecutive single fractal galaxy distributions systems possessing fractal dimension D ...

Merger relics of cluster galaxies [PDF]
Astronomy & Astrophysics, 2013 Context. Sheen and collaborators recently found that a surprisingly large portion (38%) of massive early-type galaxies in heavy clusters show strong merger-related disturbed features.

Formation of a Polar Ring Galaxy in a Galaxy Merger [PDF]
The Astrophysical Journal, 1998 We numerically investigate stellar and gas dynamics in star-forming and dissipative galaxy mergers between two disk galaxies with specific orbital configurations. We find that violent relaxation combined with gaseous dissipation in galaxy merging transforms two disk galaxies into one S0 galaxy with polar-rings: Both the central S0-like host and the ...

Jet Interaction with Galaxy Cluster Mergers
The Astrophysical JournalActive galactic nucleus (AGN) bubbles in cool-core galaxy clusters are believed to facilitate the transport of cosmic-ray electrons (CRe) throughout the cluster.

On the dependence of galaxy morphologies on galaxy mergers [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 The distribution of galaxy morphological types is a key test for models of galaxy formation and evolution, providing strong constraints on the relative contribution of different physical processes responsible for the growth of the spheroidal components.

Monthly Notices of the Royal Astronomical Society, 2009 We present the results of an Eulerian adaptive mesh refinement (AMR) hydrodynamical and N-body simulation in a $ $CDM cosmology. The simulation incorporates common cooling and heating processes for primordial gas. A specific halo finder has been designed and applied in order to extract a sample of galaxy clusters directly obtained from the simulation ...

The Merger Rate of Massive Galaxies [PDF]
The Astrophysical Journal, 2006 We calculate the projected two point correlation function for samples of luminous and massive galaxies in the COMBO-17 photometric redshift survey, focusing particularly on the amplitude of the correlation function at small projected radii and exploring the constraints such measurements can place on the galaxy merger rate.
