Multi-frequency studies of galaxies and groups: I. Environmental effect on galaxy stellar mass and morphology [PDF]
A&A 590, A29 (2016), 2016 To understand the role of the environment in galaxy formation, evolution, and present-day properties, it is essential to study the multi-frequency behavior of different galaxy populations under various environmental conditions. We crossmatch the SDSS DR10 group catalog with GAMA Data Release 2 and Wide-field Survey Explorer (WISE) data to construct a ...

FASEB BioAdvances, Volume 4, Issue 12, Page 775-797, December 2022., 2022 Abstract During initial maternal recognition of pregnancy (MRP), the equine embryo displays a series of unique events characterized by rapid blastocyst expansion, secretion of a diverse array of molecules, and transuterine migration to interact with the uterine surface.

Connecting galaxy structure and star formation: the role of environment in formation of S0 galaxies [PDF]
, 2019 In this work, we investigate the reason behind the increased occurrence of S0 galaxies in high density environments. Our sample comprises of $\sim$ 2500 spiral and $\sim$ 2000 S0 galaxies spanning a wide range of environments. Dividing the galaxies into categories of classical and pseudobulge hosting spiral and S0 galaxies, we have studied their ...

VERTICO and IllustrisTNG: The Spatially Resolved Effects of Environment on Galactic Gas
The Astrophysical Journal Letters, 2023 It has been shown in previous publications that the TNG100 simulation quantitatively reproduces the observed reduction in each of the total atomic and total molecular hydrogen gas for galaxies within massive halos, i.e., dense environments.

Galaxy interactions II: High density environments [PDF]
, 2011 With the aim to assess the role of dense environments in galaxy interactions, properties we present an analysis of close galaxy pairs in groups and clusters, obtained from the Sloan Digital Sky Survey Data Release 7 (SDSS-DR7). We identified pairs that reside in groups by cross-correlating the total galaxy pair catalogue with the SDSS-DR7 group ...

The environment of radio galaxies: A signature of AGN feedback at high redshifts [PDF]
, 2017 We use the semi-analytical model of galaxy formation GALFORM to characterise an indirect signature of AGN feedback in the environment of radio galaxies at high redshifts. The predicted environment of radio galaxies is denser than that of radio-quiet galaxies with the same stellar mass. This is consistent with observational results from the CARLA survey.

And the winner is: galaxy mass [PDF]
, 2011 The environment is known to affect the formation and evolution of galaxies considerably best visible through the well-known morphology-density relationship. We study the effect of environment on the evolution of early-type galaxies for a sample of 3,360 galaxies morphologically selected by visual inspection from the SDSS in the redshift range 0.05

Nature versus Nurture: Revisiting the Environmental Impact on Star Formation Activities of Galaxies
The Astrophysical JournalWe present a systematic study of the environmental impact on star formation activities of galaxies using a mass-complete sample of ∼170k galaxies at z < 4 from the latest COSMOS2020 catalog.

The distribution of galaxy morphological types and the morphology-mass relation in different environments at low redshift [PDF]
, 2011 We use \sim 2000 galaxies belonging to different environments to show how the fractions of different galaxy morphological types vary with global environment and as function of galaxy stellar mass at low redshift. Considering mass limited galaxy samples with log10 M\star/M\bigodot>= 10.25, we find a smooth increase/decline in the fraction of Es-S0s/late

The local environment of flat galaxies [PDF]
arXiv, 2021 The existence of flat or bulgeless galaxies poses a challenge to the hierarchical structure formation scenario advocated by modern cosmology. We determine the geometrical environment of a sample of $315$ flat galaxies from the Revised Flat Galaxy Catalog (RFGC) using `local dimension' $D$, which, on a given length scale, quantifies the dimension of the
