Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers [PDF]
The Astrophysical Journal, 2023 Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

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 $\Lambda$CDM cosmology. The simulation incorporates common cooling and heating processes for primordial gas.

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 ...

Mergers and Galaxy Assembly [PDF]
The 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1998 Theoretical considerations and observational data support the idea that mergers were more frequent in the past. At redshifts z = 2 to 5, violent interactions and mergers may be implicated by observations of Lyman-break galaxies, sub-mm starbursts, and ...

Spatially Offset Active Galactic Nuclei III: Discovery of Late-Stage Galaxy Mergers with The Hubble Space Telescope [PDF]
Astrophysical Journal, 2018 Galaxy pairs with separations of only a few kpc represent important stages in the merger-driven growth of supermassive black holes (SMBHs). However, such mergers are difficult to identify observationally due to the correspondingly small angular scales ...

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 ...

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 ...
