Radio Continuum Emission in Polar Ring Galaxies

The 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 the Interplay between Jets, Winds, and Multi-phase Gas in 11 Radio-quiet PG Quasars: A uGMRT-VLA Study

The Astrophysical Journal, 2023
We present polarization-sensitive images from the Karl G. Jansky Very Large Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio morphology, spectral index, and polarization properties from the VLA study, coupled with the findings of our

Study of nonthermal continuum patches : wave propagation and plasmapause study [PDF]

, 2011
Nonthermal continuum (NTC) radiation is believed to be emitted at the plasmapause and near the magnetic equator. We present a particular type of NTC radiation, referred to as NTC patch, which appears over a wide frequency range and within a relatively ...

Observations of Radio Continuum Emission from M 31 [PDF]

Symposium - International Astronomical Union, 1970
Observations of continuum emission from M 31 have been made with the Cambridge One-mile radio telescope (Pooley, 1969). Two observing frequencies were used; maps of the whole of the visible nebula were obtained at 408 MHz, and spectral data for the central region at 1407 MHz.

Baldwin Effect and Additional BLR Component in AGN with Superluminal Jets

Frontiers in Astronomy and Space Sciences, 2016
We study the Baldwin Effect (BE) in 96 core-jet blazars with optical and ultraviolet spectroscopic data from a radio-loud AGN sample obtained from the MOJAVE 2cm survey.

Evidence for Low-power Radio Jet–ISM Interaction at 10 pc in the Dwarf AGN Host NGC 4395

The Astrophysical Journal, 2023
Black-hole-driven outflows in galaxies hosting active galactic nuclei (AGN) may interact with their interstellar medium (ISM) affecting star formation (SF).

Continuum radio emission from the Magellanic Clouds [PDF]

Symposium - International Astronomical Union, 1964
Before discussing the results of the radio observations of the Magellanic Clouds in detail, it is worth while to briefly review some of our current ideas about radio emission from “normal” galaxies which would be the classification given to the Clouds by radio astronomers.

Radio-continuum emission from the young galactic supernova remnant G1.9+0.3 [PDF]

Serbian Astronomical Journal, 2014
We present an analysis of a new Australia Telescope Compact Array (ATCA) radio-continuum observation of supernova remnant (SNR) G1.9+0.3, which at an age of ~181±25 years is the youngest known in the Galaxy.

Laboratory astrophysics : investigation of planetary and astrophysical maser emission [PDF]

, 2013
This paper describes a model for cyclotron maser emission applicable to planetary auroral radio emission, the stars UV Ceti and CU Virginus, blazar jets and astrophysical shocks.

SYNCHROTRON EMISSION FROM THE GALACTIC HI LAYER [PDF]

Journal of Astronomy and Space Sciences, 2007
The relationship between the Galactic magnetic field strength and the gas density has been revisited. A synchrotron continuum emission data at 408 MHz and HI column density provide a good data for such study.
