Isolated Galaxies versus Interacting Pairs with MaNGA

Galaxies, 2015
We present preliminary results of the spectral analysis on the radial distributions of the star formation history in both a galaxy merger and a spiral isolated galaxy observed with MaNGA.

Tracing kinematic (mis)alignments in CALIFA merging galaxies: Stellar and ionized gas kinematic orientations at every merger stage [PDF]

, 2015
We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger stages: close companions, pairs with morphological signatures of interaction, and coalesced merger remnants.

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 ...

Simulated Galaxy Interactions as Probes of Merger Spectral Energy Distributions [PDF]

, 2014
We present the first systematic comparison of ultraviolet-millimeter spectral energy distributions (SEDs) of observed and simulated interacting galaxies.

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.

Properties of tidally-triggered vertical disk perturbations [PDF]

, 2001
We present a detailed analysis of the properties of warps and tidally-triggered perturbations perpendicular to the plane of 47 interacting/merging edge-on spiral galaxies.

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.

Two Candidates for Dual AGN in Dwarf-dwarf Galaxy Mergers

The Astrophysical Journal, 2023
Dual active galactic nuclei (DAGN) are important for understanding galaxy-merger-triggered fueling of black holes and the hierarchical growth of structures.

Probing the Physics of Interacting Galaxies

Astrophysics and Space Science, 2003
Both Arp 140 and Arp 104 reveal extended tidal tails in the HI. The Halpha and FIR fluxes of Arp 140 yield similar SFR of ~0.8 solar masses per year. In contrast the Halpha flux of Arp 104 yields a SFR of ~0.05 solar masses per year, ~ 20 times smaller than that obtained from the FIR flux.
