Isolated Galaxies versus Interacting Pairs with MaNGA [PDF]

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.

The Larson-Tinsley Effect in the UV: Interacting vs. `Normal' Spiral Galaxies [PDF]

, 2010
We compare the UV-optical colors of a well-defined set of optically-selected pre-merger interacting galaxy pairs with those of normal spirals. The shorter wavelength colors show a larger dispersion for the interacting galaxies than for the spirals. This result can best be explained by higher star formation rates on average in the interacting galaxies ...

Simulations of Dust in Interacting Galaxies [PDF]

, 2004
A new Monte-Carlo radiative-transfer code, Sunrise, is used to study the effects of dust in N-body/hydrodynamic simulations of interacting galaxies. Dust has a profound effect on the appearance of the simulated galaxies.

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.

Effect of low-mass galaxy interactions on their star formation [PDF]

A&A 681, A8 (2024), 2023
According to the $\Lambda$ cold dark matter model of galaxy formation, the hierarchical assembly process is scale-free and interactions between galaxies in all mass ranges are expected. The effects of interactions between dwarf galaxies on their evolution are not well understood.

Searching for TeV Dark Matter in Irregular Dwarf Galaxies with HAWC Observatory

The Astrophysical Journal, 2023
We present the results of dark matter (DM) searches in a sample of 31 dwarf irregular (dIrr) galaxies within the field of view of the HAWC Observatory.

Exploring the Impact of Galactic Interactions and Mergers on the Central Star Formation of APEX/EDGE–CALIFA Galaxies

The Astrophysical Journal, 2023
Galactic interactions and subsequent mergers are a paramount channel for galaxy evolution. In this work, we use the data from 236 star-forming CALIFA galaxies with integrated molecular gas observations in their central region (approximately within an ...

S0 Galaxies: Outer Gas Accretion through Tidal Interaction and Minor Merging

Galaxies, 2023
To clarify the sources of outer gas accretion onto disk galaxies, we study the vicinity of four interacting galaxy systems in the Hα emission line by using the scanning Fabry–Perot interferometer of the 6m telescope of the Special Astrophysical ...

What is driving the evolution of the far-infrared radio correlation? [PDF]

Zbornik Matice Srpske za Prirodne Nauke, 2019
Far infrared-radio correlation represents a linear relationship between far-infrared (FIR) and radio emission in star-forming galaxies. Previous observations have confirmed that this correlation is maintained over a large range of redshift and ...

Harnessing the Hubble Space Telescope Archives: A Catalog of 21,926 Interacting Galaxies

The Astrophysical Journal, 2023
Mergers play a complex role in galaxy formation and evolution. Continuing to improve our understanding of these systems requires ever larger samples, which can be difficult (even impossible) to select from individual surveys.
