Interacting galaxies in the nearby Universe: only moderate increase of star formation [PDF]
, 2015 We investigate the influence of interactions on the star formation by studying a sample of almost 1500 of the nearest galaxies, all within a distance of ~45 Mpc.

Characterization of Bars Induced by Interactions
Galaxies, 2016 Whether the formation of bars is triggered by interactions or by internal processes has been discussed for many decades. In this work, we study differences between both mechanisms by means of numerical simulations.

Self-Interacting Dark Matter and the Origin of Ultradiffuse Galaxies NGC1052-DF2 and -DF4.
Physical Review Letters, 2020 Observations of ultradiffuse galaxies NGC 1052-DF2 and -DF4 show they may contain little dark matter, challenging our understanding of galaxy formation.

A Self-interacting Dark Matter Solution to the Extreme Diversity of Low-mass Halo Properties [PDF]
Astrophysical Journal Letters, 2023 The properties of low-mass dark matter (DM) halos appear to be remarkably diverse relative to cold, collisionless DM predictions, even in the presence of baryons.

Are Disks of Satellites Comprised of Tidal Dwarf Galaxies?
Galaxies, 2021 It was found that satellites of nearby galaxies can form flattened co-rotating structures called disks of satellites or planes of satellites. Their existence is not expected by the current galaxy formation simulations in the standard dark matter-based ...

Galaxy Zoo: quantifying morphological indicators of galaxy interaction★ [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 We use Galaxy Zoo 2 visual classifications to study the morphological signatures of interaction between similar-mass galaxy pairs in the Sloan Digital Sky Survey. We find that many observable features correlate with projected pair separation; not only obvious indicators of merging, disturbance and tidal tails, but also more regular features, such as ...

Possible breaking of the FIR-radio correlation in tidally interacting galaxies [PDF]
, 2015 Far-infrared (FIR)--radio correlation is a well-established empirical connection between continuum radio and dust emission of star-forming galaxies, often used as a tool in determining star-formation rates.
