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 ...

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 ...

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 ...

Galaxy Interactions: The Hi Signature [PDF]
Symposium - International Astronomical Union, 1999 HI observations are an excellent tool for investigating tidal interactions. Ongoing major and minor interactions which can lead to traumatic mergers or to accretion and the triggering of star formation, show distinct HI signatures. Interactions and mergers in the recent past can also be recognized in the HI structure and kinematics.

The SEDs of interacting galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractThe evolution of galaxies is greatly influenced by their interactions. As part of a program to study interacting galaxies, we have measured and modeled the spectral energy distributions (SEDs) from the ultraviolet (UV) to the far-infrared (FIR).
