Galaxy interactions II: High density environments [PDF]

, 2011
With the aim to assess the role of dense environments in galaxy interactions, properties we present an analysis of close galaxy pairs in groups and clusters, obtained from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7).

On the frequency, intensity and duration of starburst episodes triggered by galaxy interactions and mergers [PDF]

, 2008
We investigate the intensity enhancement and the duration of starburst episodes, triggered by major galaxy interactions and mergers. To this aim, we analyze two large statistical datasets of numerical simulations.

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.

Effect of low-mass galaxy interactions on their star formation [PDF]

Astronomy & Astrophysics, 2023
According to the $\Lambda$ cold dark matter model of galaxy formation, the hierarchical assembly process is scale-free and interactions between galaxies in all mass ranges are expected.

Galaxy Interactions in Filaments and Sheets: Effects of the Large-scale Structures Versus the Local Density [PDF]

Research in Astronomy and Astrophysics, 2022
Major interactions are known to trigger star formation in galaxies and alter their color. We study the major interactions in filaments and sheets using SDSS data to understand the influence of large-scale environments on galaxy interactions.

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.

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 ...

Investigating the Effect of Galaxy Interactions on the Enhancement of Active Galactic Nuclei at 0.5 < z < 3.0

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 ...
