Dynamical friction of radio galaxies in galaxy clusters [PDF]
Abstract The distribution of luminous radio galaxies in galaxy clusters has been observed to be concentrated in the inner region. We consider the role of dynamical friction of massive galaxies (M∼ 1012.5M⊙), assuming them to be hosts of luminous radio galaxies, and show that beginning with a Navarro–Frenk–White density profile of a ...

ABSTRACT Damselfishes (Pomacentridae) are widespread and highly abundant on tropical coral reefs. They exhibit diverse body colouration within and between the ~250 species and across ontogenetic stages. In addition to human‐visible colours (i.e., 400–700 nm), most adult damselfishes reflect ultraviolet (UV, 300–400 nm) colour patches.

Radio Galaxy Zoo: host galaxies and radio morphologies for large surveys from visual inspection [PDF]
We present early results from Radio Galaxy Zoo, a web-based citizen science project for visual inspection and classification of images from all-sky radio surveys. The goals of the project are to classify individual radio sources (particularly galaxies with multiple lobes and/or complex morphologies) as well as matching the continuum radio emission to ...

It is now established that the faint radio population is a mixture of star-forming galaxies and faint active galactic nuclei (AGNs), with the former dominating below S(1.4GHz) \sim 100 muJy and the latter at larger flux densities.

Radio Continuum Halos of Seven Nearby Large Galaxies Using uGMRT
We present the results of deep radio observations of seven nearby large galaxies observed using the upgraded Giant Metrewave Radio Telescope (uGMRT) 0.3–0.5 GHz receivers with an angular resolution of ∼10″.

On the local radio luminosity function of galaxies. I: the Virgo cluster [PDF]
We cross-correlate the galaxies brighter than mB=18 in the Virgo cluster with the radio sources in the NVSS survey (1.4 GHz), resulting in 180 radio-optical identifications. We determine the radio luminosity function of the Virgo galaxies, separately for the early- and late-types. Late-type galaxies develop radio sources with a probability proportional

Peculiar Galaxies and Radio Sources
Pairs of radio sources which are separated by from 2° to 6° on the sky have been investigated. In a number of cases peculiar galaxies have been found approximately midway along a line joining the two radio sources. The central peculiar galaxies belong mainly to a certain class in the recently compiled Atlas of Peculiar Galaxies
