The environment of HII galaxies revisited [PDF]
Astronomy & Astrophysics, 2013 We present a study of the close (< 200 kpc) environment of 110 relatively local (z< 0.16) HII galaxies, selected from the Sloan Digital Sky Survey (SDSS; DR7). We use available spectroscopic and photometric redshifts in order to investigate the presence of a close and possibly interacting companion galaxy.

Harassment Origin for Kinematic Substructures in Dwarf Elliptical Galaxies? [PDF]
, 2005 We have run high resolution N-body models simulating the encounter of a dwarf galaxy with a bright elliptical galaxy. The dwarf absorbs orbital angular momentum and shows counter-rotating features in the external regions of the galaxy.

Properties of galaxies in SDSS Quasar environments at z < 0.2 [PDF]
, 2006 We analyse the environment of low redshift, z < 0.2, SDSS quasars using the spectral and photometric information of galaxies from the Sloan Digital Sky Survey Third Data Release (SDSS-DR3).

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

Tailed radio galaxies as tracers of galaxy clusters. Serendipitous discoveries with the GMRT [PDF]
, 2009 We report on the discovery of four new radio galaxies with tailed morphology. Tailed radio galaxies are generally found in rich environments, therefore their presence can be used as tracer of a cluster.

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.

Reconstructing the galaxy density field with photometric redshifts: II. Environment-dependent galaxy evolution since $z \simeq 3$ [PDF]
, 2017 Although extensively investigated, the role of the environment in galaxy formation is still not well understood. In this context, the Galaxy Stellar Mass Function (GSMF) is a powerful tool to understand how environment relates to galaxy mass assembly and

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 ...
