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.

Deep Learning for Galaxy Mergers in the Galaxy Main Sequence [PDF]
Proceedings of the International Astronomical Union, 2019 Starburst galaxies are often found to be the result of galaxy mergers. As a result, galaxy mergers are often believed to lie above the galaxy main sequence: the tight correlation between stellar mass and star formation rate.

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 ...

On the Frequency of Multiple Galaxy Mergers in ΛCDM Cosmological Simulations
The Astrophysical JournalMergers are believed to play a pivotal role in galaxy evolution, and measuring the galaxy merger fraction is a longstanding goal of both observational and theoretical studies.

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.

Galaxy Mergers Moulding The Cgm
, 2017 Galaxies are surrounded by sizeable gas reservoirs which host a significant amount of metals: the circum-galactic medium (CGM). The CGM acts as a mediator between the galaxy and the extra-galactic medium. However, our understanding of how galaxy mergers, a major evolutionary transformation, impact the CGM remains deficient.

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
