“E+A” Galaxies: Environment and Evolution [PDF]
One important approach to the study of galaxy evolution is to identify those galaxies whose spectral and/or morphological characteristics suggest that they are in transition. For example, “E+A” galaxies, which have strong Balmer absorption lines and no significant [OII] emission, are generally interpreted as post-starburst galaxies in which the star ...

Dwarf galaxies located in extremely underdense cosmic voids are excellent test beds for disentangling the effects of large-scale environments on galaxy formation and evolution. We present the first results of the Dwarfs in Void Environments Survey, which

Measures of galaxy environment - I. What is ‘environment’?
The influence of a galaxy's environment on its evolution has been studied and compared extensively in the literature, although differing techniques are often used to define environment. Most methods fall into two broad groups: those that use nearest neighbours to probe the underlying density field and those that use fixed apertures.

Inside-out versus Outside-in Quenching of MaNGA Galaxies: Dependence on Stellar Mass and Environment
Galaxy quenching, the cessation of star formation, can proceed in spatially distinct ways, commonly described as inside-out or outside-in. However, the inferred quenching pattern depends strongly on how quenched or quenching regions are defined ...

Nature versus Nurture: Revisiting the Environmental Impact on Star Formation Activities of Galaxies
We 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.

We explore the morphological features and star formation activities of [O ii ] emitters in the COSMOS UltraDeep field at z ∼ 1.5 using JWST NIRCam data from the COSMOS-Web survey and Subaru Hyper Suprime-Cam.

We study the mass–size relation of quiescent galaxies across various environments, with a particular focus on its environmental dependence at the low-mass part of $\mathrm{log}({M}_{\mathrm{star}}/{M}_{\odot })\lesssim 10.0$ .

The stellar mass–size relation is a sensitive probe of how environment shapes galaxy structure. We analyse this relation in the local Universe for galaxies in compact groups (CGs), low-mass groups ( M _vir ≤ 10 ^13 M _⊙ ), and high-mass groups, comparing

The Environments of Radio Galaxies [PDF]
In the unified schemes of AGNs BL Lac objects are believed to be Fanaroff-Riley (FR) type I radio galaxies with a relativistic jet aligned to the observer's line of sight (e.g. Urry & Padovani 1995). Kollgaard et al. (1992) and Owen et al. (1995) suggest some FR II sources can also be BL Lac parents. Clearly, isotropic properties such as the galaxy
