The Effect of Galaxy Interactions on Molecular Gas Properties [PDF]
Astrophysical Journal, 2018 Galaxy interactions are often accompanied by an enhanced star formation rate (SFR). Since molecular gas is essential for star formation, it is vital to establish whether and by how much galaxy interactions affect the molecular gas properties.

The changing GMC population in galaxy interactions [PDF]
Monthly notices of the Royal Astronomical Society, 2018 With the advent of modern observational efforts providing extensive giant molecular cloud catalogues, understanding the evolution of such clouds in a galactic context is of prime importance.

Galaxy Interactions Trigger Rapid Black Hole Growth: an unprecedented view from the Hyper Suprime-Cam Survey [PDF]
, 2017 Collisions and interactions between gas-rich galaxies are thought to be pivotal stages in their formation and evolution, causing the rapid production of new stars, and possibly serving as a mechanism for fueling supermassive black holes (BH).

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

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 ...

Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies
The Astrophysical Journal Letters, 2023 Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.

Self-interacting dark matter on small and large scales
SciPost Physics Proceedings, 2023 In the self-interacting dark matter paradigm (hereafter SIDM), dark matter (DM) is assumed to have non-gravitational interactions with itself. SIDM has been constrained by observations of galaxy clusters. More recently, measurements of large DM densities
