KINEMATIC CLASSIFICATIONS OF LOCAL INTERACTING GALAXIES: IMPLICATIONS FOR THE MERGER/DISK CLASSIFICATIONS AT HIGH-z [PDF]
, 2015 The classification of galaxy mergers and isolated disks is key for understanding the relative importance of galaxy interactions and secular evolution during the assembly of galaxies. Galaxy kinematics as traced by emission lines have been used to suggest

A HYPER SUPRIME-CAM VIEW OF THE INTERACTING GALAXIES OF THE M81 GROUP [PDF]
, 2015 We present the first results of a wide-field mapping survey of the M81 group conducted with Hyper Suprime-Cam on the Subaru Telescope. Our deep photometry reaches ∼2 mag below the tip of the red giant branch (RGB) and reveals the spatial distribution of ...

SIDM on FIRE: hydrodynamical self-interacting dark matter simulations of low-mass dwarf galaxies. [PDF]
Monthly notices of the Royal Astronomical Society, 2017 We compare a suite of four simulated dwarf galaxies formed in 1010 M☉ haloes of collisionless cold dark matter (CDM) with galaxies simulated in the same haloes with an identical galaxy formation model but a non-zero cross-section for DM self-interactions.

Dynamically regulated star formation in the strongly interacting Taffy galaxies [PDF]
EPJ Web of Conferences, 2022 The Taffy system stands out as one of the strongest gas-rich galaxy mergers with little star formation (SF) activity. We study the causes of this SF inefficiency by observing with the IRAM 30m telescope the line emission of several species in 6 positions.

Modelling ISO Galaxy Counts with Luminosity and Merger Rate Evolution [PDF]
, 1998 We model galaxy evolution in the 6.75 and 15 micron passbands of the ISO satellite, by combining models of galaxy evolution at optical wavelengths (which are consistent with the optical galaxy counts) with observed spectral energy distributions in the ...

EXTRA-NUCLEAR STARBURSTS: YOUNG LUMINOUS HINGE CLUMPS IN INTERACTING GALAXIES [PDF]
, 2014 Hinge clumps are luminous knots of star formation near the base of tidal features in some interacting galaxies. We use archival Hubble Space Telescope (HST) UV/optical/IR images and Chandra X-ray maps along with Galaxy Evolution Explorer UV, Spitzer IR ...

Tidal Disruption of Milky Way Satellites with Shallow Dark Matter Density Profiles
Galaxies, 2016 Dwarf galaxies of the Local Group provide unique possibilities to test current theories of structure formation. Their number and properties have put the broadly accepted cold dark matter model into question, posing a few problems. These problems now seem

Scale Interactions and Galaxy Evolution [PDF]
Astrophysics and Space Science, 2003 To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

Optical imaging for the Spitzer Survey of Stellar Structure in Galaxies. Data release and notes on interacting galaxies [PDF]
, 2014 (Abridged) The Spitzer Survey for Stellar Structure in Galaxies (S4G) and its more recently approved extension will lead to a set of 3.6 and 4.5 micron images for 2829 galaxies, which can be used to study many different aspects of the structure and ...
