Multi-frequency radio continuum mapping of giant radio galaxies [PDF]

Astronomy and Astrophysics Supplement Series, 1997
The giant radio galaxies NGC 315, DA 240, 3C 236, 3C 326, and NGC 6251 have been observed at 92 cm and 49 cm wavelengths with the Westerbork Synthesis Radio Telescope (WSRT) and at , 6.3 cm, and 2.8 cm using the Effelsberg 100-m telescope. These objects all exhibit strong polarized radio emission across the entire radio frequency domain. Their spectral

CHANG-ES. XXVI. radio images of 5 galaxies [Dataset] [PDF]

, 2023
Galactic winds play a key role in regulating the evolution of galaxies over cosmic time. In recent years, the role of cosmic rays (CRs) in the formation of the galactic wind has increasingly gained attention.

Radio continuum from the most massive early-type galaxies detected with ASKAP RACS [PDF]

, 2023
All very massive early-type galaxies contain supermassive blackholes but are these blackholes all sufficiently active to produce detectable radio continuum sources? We have used the 887.5 MHz Rapid ASKAP Continuum Survey DR1 to measure the radio emission

Characteristics of remnant radio galaxies detected in deep radio continuum observations from SKA pathfinders [PDF]

, 2022
The cessation of AGN activity in radio galaxies leads to a remnant phase during which jets are no longer sustained, but lobes can be detected for a period of time before they fade away due to radiative and dynamical energy losses.

Characterizing the radio continuum emission from intense starburst galaxies [PDF]

, 2016
The intrinsic thermal (free–free) and non-thermal (synchrotron) emission components that comprise the radio continuum of galaxies represent unique, dust-free measures of star formation rates (SFR). Such high SFR galaxies will dominate the deepest current

Radio continuum spectra of galaxies in the Virgo cluster region [PDF]

, 2004
New radio continuum observations of galaxies in the Virgo cluster region at 4.85, 8.6, and 10.55 GHz are presented. These observations are combined with existing measurements at 1.4 and 0.325 GHz.

Radio continuum, CO, and thermal infrared emission in nearby star-forming galaxies [PDF]

, 2007
The correlation between far-infrared and radio emission in galaxies is remarkably strong considering the very different emission mechanisms which are thought to be responsible for the two.

Stellar feedback in dwarf irregular galaxies with radio continuum observations [PDF]

, 2019
Low-mass dwarf irregular galaxies are subject to outflows, in which cosmic rays may play a very important role; they can be traced via their electron component, the cosmic ray electrons (CRe), in the radio continuum as non-thermal synchrotron emission ...
