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.

On the characteristics of tidal structures of interacting galaxies [PDF]
, 2011 We present the results of our analysis of the geometrical tidal tail characteristics for nearby and distant interacting galaxies. The sample includes more than two hundred nearby galaxies and about seven hundred distant ones.

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.

Triggering Star Formation by Galaxy-Galaxy Interactions [PDF]
Symposium - International Astronomical Union, 2004 We analyzed the effects of having a close companion on the star formation activity of galaxies in the 8K galaxy pair catalog selected from the 2dFGRS. We found that, statistically, galaxies with rp < 25h−1 kpc and ΔV < 100km s−1 have enhanced star formation with respect to isolated galaxies with the same luminosity and redshift distribution.

Galaxy Zoo: Mergers – Dynamical models of interacting galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 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 into the processes that lead to enhanced star formation.

INTERACTIONS OF GALAXIES IN THE GALAXY CLUSTER ENVIRONMENT [PDF]
The Astrophysical Journal, 2009 We study the dependence of galaxy properties on the clustercentric radius and the environment attributed to the nearest neighbor galaxy using the SDSS galaxies associated with the Abell galaxy clusters. We find that there exists a characteristic scale where the properties of galaxies suddenly start to depend on the clustercentric radius at fixed ...

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 ...
