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 ...

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.

Real galaxy mergers from galaxy pair catalogues [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Mergers of galaxies are extremely violent events shaping their evolution. Such events are thought to trigger starbursts and, possibly, black hole accretion. Nonetheless, it is still not clear how to know the fate of a galaxy pair from the data available at a given time, limiting our ability to constrain the exact role of mergers.

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 ...

Magnetic fields during galaxy mergers [PDF]
Astronomy & Astrophysics, 2016 Galaxy mergers are expected to play a central role for the evolution of galaxies, and may have a strong impact on their magnetic fields. We present the first grid-based 3D magneto-hydrodynamical simulations investigating the evolution of magnetic fields during merger events. For this purpose, we employ a simplified model considering the merger event of

Galaxy Zoo: Mergers – Dynamical models of interacting galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 The dynamical history of most merging galaxies is not well understood. Correlations between galaxy interaction and star formation have been found in previous studies, but require the context of the physical history of merging systems for full insight into the processes that lead to enhanced star formation.

MOST SUBMILLIMETER GALAXIES ARE MAJOR MERGERS [PDF]
The Astrophysical Journal, 2010 We analyse subarcsecond resolution interferometric CO line data for twelve sub-millimetre-luminous (S850um > 5mJy) galaxies with redshifts between 1 and 3, presenting new data for four of them. Morphologically and kinematically most of the twelve systems appear to be major mergers. Five of them are well-resolved binary systems, and seven are compact

Warm Molecular Gas in Galaxy-Galaxy Merger NGC 6090 [PDF]
The Astrophysical Journal, 2004 We present observations of the CO 2-1 and 3-2 transitions toward the merging galaxies of NGC6090 with the Submillimeter Array (SMA) (The Submillimeter Array (SMA) is a joint project between the Smithsonian Astrophysical Observatory and the Academia Sinica Institute of Astronomy and Astrophysics, and is funded by the Smithsonian Institution and the ...

Merger driven explosive evolution of distant galaxies (minor mergers) [PDF]
Astrophysical Bulletin, 2013 We derived solutions for the Smoluchowski kinetic equation for the mass function of galaxies, which describes mergers in differential approximation, where mergers with low-mass galaxies are the dominant factor. The evolution of the initial distribution is analyzed as well as the influence of the source represented by galaxies (halos) that separate from
