The Astrophysical Journal, 2023 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

The gaseous environments of radio galaxies [PDF]
New Astronomy Reviews, 2002 X-ray emission traces the gaseous environments of radio sources. The medium must be present for jet confinement, but what are its influence on jet fuelling, dynamics, propagation, and disruption? The observational situation is both complicated and enriched by radio sources being multi-component X-ray emitters, with several possible regions of non ...

Deep Synoptic Array Science: A Massive Elliptical Host Among Two Galaxy-cluster Fast Radio Bursts
The Astrophysical Journal, 2023 The stellar population environments that are associated with fast radio burst (FRB) sources provide important insights for developing their progenitor theories.

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).

The Astrophysical Journal, 2023 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 $\mathrm{log}({M}_{\mathrm{star}}/{M}_{\odot })\lesssim 10.0$ .

“E+A” Galaxies: Environment and Evolution [PDF]
Symposium - International Astronomical Union, 1999 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 ...

The Environments of Radio Galaxies [PDF]
Symposium - International Astronomical Union, 1996 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

Evolution and Environment of Early-Type Galaxies [PDF]
The Astronomical Journal, 2006 We study the photometric and spectral properties of 39320 early-type galaxies within the SDSS, as a function of both local environment and redshift. The distance to the nearest cluster of galaxies and the distance to the 10th nearest luminous neighbor were used to define two extremes in environment.
