Star formation triggered by galaxy interactions in modified gravity [PDF]
, 2016 Together with interstellar turbulence, gravitation is one key player in star formation. It acts both at galactic scales in the assembly of gas into dense clouds, and inside those structures for their collapse and the formation of pre-stellar cores.

THE SAMI GALAXY SURVEY: GALAXY INTERACTIONS AND KINEMATIC ANOMALIES IN ABELL 119 [PDF]
, 2016 Galaxy mergers are important events that can determine the fate of a galaxy by changing its morphology, star formation activity and mass growth. Merger systems have commonly been identified from their disturbed morphologies, and we now can employ ...

Effects of galaxy interactions in different environments [PDF]
, 2006 We analyse star formation rates derived from photometric and spectroscopic data of galaxies in pairs in different environments using the 2dF Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS).

On the Effects of Local Environment on Active Galactic Nucleus (AGN) in the Horizon Run 5 Simulation
The Astrophysical Journal, 2023 We use the Horizon Run 5 cosmological simulation to study the effect of galaxy intrinsic properties and the local environment on active galactic nuclei (AGNs) characterized by their threshold of the accretion rate.

Galaxy interactions in compact groups – II. Abundance and kinematic anomalies in HCG 91c [PDF]
, 2015 Galaxies in Hickson Compact Group 91 (HCG 91) were observed with the WiFeS integral field spectrograph as part of our ongoing campaign targeting the ionized gas physics and kinematics inside star forming members of compact groups.

A Multiwavelength Study of Active Galactic Nuclei in Post-merger Remnants
The Astrophysical Journal, 2023 We investigate the role of galaxy mergers in triggering active galactic nuclei (AGN) in the nearby universe. Our analysis is based on a sample of 79 post-merger remnant galaxies with deep X-ray observations from Chandra/XMM-Newton capable of detecting a ...

The HI content of the Eridanus group of galaxies [PDF]
, 2004 The HI content of galaxies in the Eridanus group is studied using the GMRT observations and the HIPASS data. A significant HI deficiency up to a factor of 2-3 is observed in galaxies in the high galaxy density regions.

The role of dwarf galaxy interactions in shaping the Magellanic System and implications for Magellanic Irregulars [PDF]
, 2012 We present a novel pair of numerical models of the interaction history between the Large and Small Magellanic Clouds (LMC and SMC, respectively) and our Milky Way (MW) in light of recent high-precision proper motions from the Hubble Space Telescope ...
