Astrophysical Journal, 2007 We compare the use of galaxy asymmetry and pair proximity for measuring galaxy merger fractions and rates for a volume limited sample of 3184 galaxies with -21 < M(B) -5 log h < -18 mag.

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

MEGA: merger graphs of structure formation [PDF]
, 2020 When following the growth of structure in the Universe, we propose replacing merger trees with merger graphs, in which haloes can both merge and split into separate pieces.

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 ...

Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers
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.

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

Merger relics of cluster galaxies [PDF]
, 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.

Mergers and galaxy assembly [PDF]
The 9th astrophysics conference: After the dark ages, when galaxies were young (the Universe at 2<Z<5), 1999 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 active galactic nuclei.
