The Astrophysical Journal, 2023 Pairs of galaxies hosting active galactic nuclei (AGNs) are powerful probes of merger-driven supermassive black hole (SMBH) growth as they can resolve individual AGNs and trace mergers over a large range of physical separations.

Impact of galaxy mergers on the colours of cluster galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT We examine the ultraviolet and optical colours of 906 cluster galaxies from the KASI-Yonsei Deep Imaging Survey of Clusters (KYDISC). The sample has been divided into two categories, morphologically disturbed and undisturbed galaxies, based on the visual signatures related to recent mergers. We find that galaxies with signatures

Automatic quantitative morphological analysis of interacting galaxies [PDF]
, 2013 The large number of galaxies imaged by digital sky surveys reinforces the need for computational methods for analyzing galaxy morphology. While the morphology of most galaxies can be associated with a stage on the Hubble sequence, morphology of galaxy ...

The Effect of Mass Ratio on the Morphology and Time-scales of Disc Galaxy Mergers [PDF]
, 2009 The majority of galaxy mergers are expected to be minor mergers. The observational signatures of minor mergers are not well understood, thus there exist few constraints on the minor merger rate.

Molecular Gas and Star Formation in Nearby Starburst Galaxy Mergers
The Astrophysical Journal, 2023 We employ the Feedback In Realistic Environments (FIRE-2) physics model to study how the properties of giant molecular clouds (GMCs) evolve during galaxy mergers.

Observational Constraints on Correlated Star Formation and Active Galactic Nuclei in Late-stage Galaxy Mergers [PDF]
, 2017 Galaxy mergers are capable of triggering both star formation and active galactic nuclei (AGNs) and therefore may represent an important pathway in the co-evolution of galaxies and supermassive black holes (SMBHs).

Spatially Offset Active Galactic Nuclei. II. Triggering in Galaxy Mergers [PDF]
, 2017 Galaxy mergers are likely to play a role in triggering active galactic nuclei (AGNs), but the conditions under which this process occurs are poorly understood.

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

Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Optical, and X-ray (ICM-SHOX) [PDF]
EPJ Web of ConferencesGalaxy cluster mergers are representative of a wide range of physics, making them an excellent probe of the properties of dark matter and the ionized plasma of the intracluster medium.
