Galaxies with monstrous black holes in galaxy cluster environments [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
Massive early-type galaxies follow a tight relation between the mass of their central supermassive black hole ($\rm M_{BH}$) and their stellar mass ($\rm M_{\star}$). The origin of observed positive outliers from this relation with extremely high $\rm M_{BH}$ ($> 10^{9} M_{\odot}$) remains unclear.

EXTREMELY METAL-POOR GALAXIES: THE ENVIRONMENT [PDF]

The Astrophysical Journal, 2015
We have analyzed bibliographical observational data and theoretical predictions, in order to probe the environment in which extremely metal-poor dwarf galaxies (XMPs) reside. We have assessed the HI component and its relation to the optical galaxy, the cosmic web type (voids, sheets, filaments and knots), the overdensity parameter and analyzed the ...

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 ...

Galaxy evolution in the environment of ABCG 209 [PDF]

Astronomy & Astrophysics, 2004
We examine the environmental effects on the photometric properties of galaxies for the rich galaxy cluster ABCG 209 at z=0.209. We use archive CFHT optical imaging of a 42'x28' field centred on the cluster to produce a galaxy sample complete to B=25.0 and R=24.5.

The local environment of H II galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2000
We address the question of whether violent star formation in HII galaxies is induced by low mass companions by describing statistically their local environment as estimated by the correlation function. We argue that even if low mass companions were mainly intergalactic HI clouds, their optical counterparts should be detectable at faint limits of the ...

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 ...

The environments of the radio galaxy population in simba [PDF]

Monthly Notices of the Royal Astronomical Society, 2022
ABSTRACT We investigate the environmental properties of the z = 0 radio galaxy population using the simba cosmological hydrodynamic simulation. We identify centrals and satellites from a population of high and low excitation radio galaxies (HERGs and LERGs) in simba, and study their global properties.
