Radio Galaxies and Their Environment [PDF]
In this paper we review the properties of radio galaxies in connection to the effect of the dynamic gaseous environment inside clusters in which they are embedded. The external gas can interact with a radio source in different ways: modifying its morphology via ram-pressure, confining the radio lobes, possibly feeding the active nucleus, enhancing star

A repeating fast radio burst source localized to a nearby spiral galaxy
Nature, 2020Fast radio bursts (FRBs) are brief, bright, extragalactic radio flashes1,2. Their physical origin remains unknown, but dozens of possible models have been postulated3. Some FRB sources exhibit repeat bursts4–7.

Disk galaxies and their environment
Astronomische Nachrichten, 2009AbstractEnvironments of disk‐dominated galaxies and simple disk systems‐compared to systems with bulges‐provide a means to explore how environment relates to galaxy morphology. Our approach focuses on systems with edge‐on disks where disk‐to‐bulge ratios and disk flattening can be unambiguously determined and focuses on simple disks as evolutionary ...

Seyfert Galaxies And Their Environment
Symposium - International Astronomical Union, 1999The role played by environment on nuclear activity in galaxies is not clear and largely debated (see e.g. Barnes & Hernquist 1992, Kelm 1996). To overcome statistical uncertainties, environment properties of two large samples of Seyfert galaxies (Sy 1 and Sy 2 have been kept separated) have been computed and compared with equivalent size “normal ...

Markarian galaxies and their environment [PDF]
The relationship between the characteristics of Markarian galaxies (MGs) and those of galaxy groups is studied. The list that we have compiled by a physically justified method is used as galaxy groups. The following results have been obtained. (1) The frequency of occurrence of MGs in rich groups is lower than that in poor groups and single galaxies ...

Galaxies and Their Environments
Publications of the Astronomical Society of the Pacific, 1995Four questions are asked related to galaxies and their environments in the context of speculation as to which direction the field may go over the next decade. These are: What is a galaxy? Where does a galaxy end? Are galaxies open or closed? and How important are interactions?
