Effects of galaxy interactions in different environments [PDF]
, 2006 We analyse star formation rates derived from photometric and spectroscopic data of galaxies in pairs in different environments using the 2dF Galaxy Redshift Survey (2dFGRS) and the Sloan Digital Sky Survey (SDSS).

Pre-Processing and Post-Processing in Group-Cluster Mergers [PDF]
, 2013 Galaxies in clusters are more likely to be of early type and to have lower star formation rates than galaxies in the field. Recent observations and simulations suggest that cluster galaxies may be `pre-processed' by group or filament environments and ...

COSMOS2020: Discovery of a Protocluster of Massive Quiescent Galaxies at z = 2.77
The Astrophysical Journal Letters, 2023 Protoclusters of galaxies have been found in the last quarter-century. However, most of them have been found through the overdensity of star-forming galaxies, and there have been no known structures identified by more than two spectroscopically confirmed

The Environmental Dependence of the Evolving S0 Fraction [PDF]
, 2010 We reinvestigate the dramatic rise in the S0 fraction, f_S0, within clusters since z ~ 0.5. In particular, we focus on the role of the global galaxy environment on f_S0 by compiling, either from our own observations or the literature, robust line-of ...

The Astrophysical Journal, 2023 Growing evidence in support of a connection between active galactic nuclei (AGN) activity and the ram pressure stripping (RPS) phenomenon has been found both observationally and theoretically in the past decades.

How environment drives galaxy evolution: Lessons learnt from satellite galaxies [PDF]
Astronomische Nachrichten, 2015 AbstractIt is by now well established that galaxy evolution is driven by intrinsic and environmental processes, both contributing to shape the observed properties of galaxies. A number of early studies, both observational and theoretical, have shown that the star formation activity of galaxies depends on their environmental local density and also on ...

The Astrophysical Journal, 2023 We study how environment regulates the star formation cycle of 33 Virgo Cluster satellite galaxies on 720 pc scales. We present the resolved star-forming main sequence for cluster galaxies, dividing the sample based on their global H i properties and ...

The Environment of Barred Galaxies Revisited [PDF]
, 2016 We present a study of the environment of barred galaxies using galaxies drawn from the SDSS. We use several different statistics to quantify the environment: the projected two-point cross-correlation function, the background-subtracted number count of neighbor galaxies, the overdensity of the local environment, the membership of our galaxies to galaxy ...
