The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons [PDF]
, 2017 We present the first simulated galaxy clusters (M200 > 1014 M⊙) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater diversity in both dark matter and stellar density profiles than their counterparts in simulations ...

The NGC 1614 interacting galaxy Molecular gas feeding a "ring of fire" [PDF]
, 2013 Minor mergers frequently occur between giant and gas-rich low-mass galaxies and can provide significant amounts of interstellar matter to refuel star formation and power active galactic nuclei (AGN) in the giant systems.

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 ...

Mid-Infrared Evidence for Accelerated Evolution in Compact Group Galaxies [PDF]
, 2009 We find evidence for accelerated evolution in compact group galaxies from the distribution in mid-infrared colorspace of 42 galaxies from 12 Hickson Compact Groups (HCGs) compared to the the distributions of several other samples including the LVL+SINGS ...

A rumble in the dark: signatures of self-interacting dark matter in supermassive black hole dynamics and galaxy density profiles [PDF]
, 2017 We explore for the first time the effect of self-interacting dark matter (SIDM) on the dark matter (DM) and baryonic distribution in massive galaxies formed in hydrodynamical cosmological simulations, including explicit baryonic physics treatment.

Gas inflow and outflow in an interacting high-redshift galaxy. The remarkable host environment of GRB 080810 at z = 3.35 [PDF]
, 2017 We reveal multiple components of an interacting galaxy system at z ≈ 3.35 through a detailed analysis of the exquisite high-resolution Keck/HIRES spectrum of the afterglow of a gamma-ray burst (GRB). Through Voigt-profile fitting of absorption lines from

Dust Deficiency in the Interacting Galaxy NGC 3077
Galaxies, 2017 Using 70 μ m observations taken with the PACS instrument of the Herschel space telescope, the dust content of the nearby and interacting spiral galaxy NGC 3077 has been compared with the dust content of the isolated galaxies such as NGC 2841, NGC ...
