Central star formation and metallicity in CALIFA interacting galaxies [PDF]
, 2015 We use optical integral-field spectroscopic (IFS) data from 103 nearby galaxies at different stages of the merging event, from close pairs to merger remnants provided by the CALIFA survey, to study the impact of the interaction in the specific star ...

ChAInGeS: THE CHANDRA ARP INTERACTING GALAXIES SURVEY [PDF]
, 2012 We have conducted a statistical analysis of the ultra-luminous X-ray point sources (ULXs; LX ⩾ 1039 erg s−1) in a sample of galaxies selected from the Arp Atlas of Peculiar Galaxies.

A COMPARATIVE STUDY OF KNOTS OF STAR FORMATION IN INTERACTING VERSUS SPIRAL GALAXIES [PDF]
, 2016 Interacting galaxies are known to have higher global rates of star formation on average than normal galaxies, relative to their stellar masses. Using UV and IR photometry combined with new and published Hα images, we have compared the star formation ...

Magnetic field evolution in interacting galaxies [PDF]
, 2011 Aims. Violent gravitational interactions can change the morphologies of galaxies and, by means of merging, transform them into elliptical galaxies. We aim to investigate how they affect the evolution of galactic magnetic fields. Methods.

Velocity-dependent self-interacting dark matter from groups and clusters of galaxies [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We probe the self-interactions of dark matter with relaxed galaxy groups and clusters using observational data from strong and weak lensing and stellar kinematics.

A diversity of starburst-triggering mechanisms in interacting galaxies and their signatures in CO emission [PDF]
Astronomy & Astrophysics, 2019 The physical origin of enhanced star formation activity in interacting galaxies remains an open question. Knowing whether starbursts are triggered by an increase in the quantity of dense gas or an increase in the star formation efficiency therein would ...

Constraining velocity-dependent self-interacting dark matter with the Milky Way’s dwarf spheroidal galaxies [PDF]
, 2020 The observed anti-correlation between the central dark matter (DM) densities of the bright Milky Way (MW) dwarf spheroidal galaxies (dSphs) and their orbital pericenter distances poses a potential signature of self-interacting dark matter (SIDM). In this

ALMA CO Clouds and Young Star Complexes in the Interacting Galaxies IC 2163 and NGC 2207 [PDF]
, 2017 Atacama Large Millimeter Array (ALMA) observations of CO(1-0) emission in the interacting galaxies IC 2163 and NGC 2207 are used to determine the properties of molecular clouds and their association with star-forming regions observed with the Hubble ...

Testing the Radio-selection Method of Dual Active Galactic Nuclei in the Stripe 82 Field
The Astrophysical Journal, 2023 We test the merger-induced dual active galactic nuclei (dAGNs) paradigm using a sample of 35 radio galaxy pairs from the Sloan Digital Sky Survey Stripe 82 field.

Galaxy Zoo: Mergers – Dynamical models of interacting galaxies [PDF]
, 2016 The dynamical history of most merging galaxies is not well understood. Correlations between galaxy interaction and star formation have been found in previous studies, but require the context of the physical history of merging systems for full insight ...
