Radio continuum spectra of gigahertz-peaked spectrum galaxies [PDF]

open access: bronzeAstronomy & Astrophysics, 2007
Context. Recent studies have shown that a remarkable share of quasars classified in the literature as gigahertz-peaked spectrum (GPS) sources and high frequency peakers (HFPs) are actually flaring flat-spectrum sources or blazars. Thus, at least among the quasar-type samples, genuine GPS sources and HFPs seem to be rare. Aims.

Radio Continuum Emission in Polar Ring Galaxies [PDF]

open access: bronzeThe Astronomical Journal, 2004
We have used the Very Large Array aperture synthesis telescope to conduct a radio continuum survey of polar-ring galaxies, at 20cm and 6cm. Forty objects were observed at 20cm with 5" resolution. Twenty (50%) of the program sources were detected at 20cm, down to our 5-sigma limit of 0.5 mJy/beam.

Probing Galaxy Evolution Through Deep Radio Continuum Observations

open access: green, 2021
One of the most important questions in modern astrophysics is how galaxies form and evolve. There are numerous processes involved in galaxy evolution, but the stellar mass buildup and supermassive black hole growth are two main drivers in galaxy evolution. Those activities are heavily obscured by dust, so we need another tracer without dust attenuation:

Radio continuum properties of OH megamaser galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We present a study of the radio continuum properties of two luminous/ultraluminous infrared galaxy samples: the OH megamaser (OHM) sample (74 objects) and the control sample (128 objects) without detected maser emission. We carried out pilot observations for 140 objects with the radio telescope RATAN-600 at 1.2, 2.3, 4.7, 8.2 ...

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

open access: yesAstronomy 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
