Star formation efficiency in galaxy interactions and mergers: a statistical study [PDF]
, 2007 We investigate the enhancement of star formation efficiency in galaxy interactions and mergers by numerical simulations of several hundred galaxy collisions.

THE ORIGIN OF NEUTRAL HYDROGEN CLOUDS IN NEARBY GALAXY GROUPS: EXPLORING THE RANGE OF GALAXY INTERACTIONS [PDF]
, 2011 We combine high-resolution N-body simulations with deep observations of neutral hydrogen (H i) in nearby galaxy groups in order to explore two well-known theories of H i cloud formation: H i stripping by galaxy interactions and dark-matter minihalos with

COMBINED EFFECTS OF GALAXY INTERACTIONS AND LARGE-SCALE ENVIRONMENT ON GALAXY PROPERTIES [PDF]
, 2009 We inspect the coupled dependence of physical parameters of the Sloan Digital Sky Survey galaxies on the small-scale (distance to and morphology of the nearest neighbor galaxy) and the large-scale (background density smoothed over 20 nearby galaxies ...

Galaxy interactions I: Major and minor mergers [PDF]
, 2011 Aims. We study galaxy pair samples selected from the Sloan Digital Sky Survey (SDSS-DR7) and we perform an analysis of minor and major mergers with the aim of investigating the dependence of galaxy properties on interactions. Methods.

Galaxy interactions are the dominant trigger for local type 2 quasars [PDF]
Monthly notices of the Royal Astronomical Society, 2023 The triggering mechanism for the most luminous, quasar-like active galactic nuclei (AGN) remains a source of debate, with some studies favouring triggering via galaxy mergers and others finding little evidence in support of this mechanism.

Spatially resolved star formation and fuelling in galaxy interactions [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We investigate the spatial structure and evolution of star formation and the interstellar medium (ISM) in interacting galaxies. We use an extensive suite of parsec-scale galaxy-merger simulations (stellar mass ratio = 2.5:1), which employs the ...

SDSS-IV MaNGA: Spatial Evolution of Star Formation Triggered by Galaxy Interactions [PDF]
Astrophysical Journal, 2019 Galaxy interaction is considered a key driver of galaxy evolution and star formation (SF) history. In this paper, we present an empirical picture of the radial extent of interaction-triggered SF along the merger sequence.

The Astronomical Journal, 2023 We report VLA B-configuration observations of the H i 21 cm line on the close disk galaxy pair NGC 5595 and NGC 5597. At the angular resolution of the observations, ∼7.″1 × 4.″2, while most of the H i 21 cm in NGC 5595 and NGC 5597 has the same extent as

Evidence for Ultra-diffuse Galaxy “Formation” through Galaxy Interactions [PDF]
Astrophysical Journal, 2018 We report the discovery of two ultra-diffuse galaxies (UDGs) that show clear evidence of an association with tidal material and an interaction with a larger galaxy halo, found during a search of the Wide portion of the Canada–France–Hawaii Telescope ...

Astrophysical Journal, 2020 Galaxy interactions and mergers are thought to play an important role in the evolution of galaxies. Studies in the nearby universe show a higher fraction of active galactic nuclei (AGNs) in interacting and merging galaxies than in their isolated ...
