Radio Continuum Spectra of Planetary Nebulae
Galaxies, 2018 Radio continuum emission of planetary nebulae is a rich source of information about their structure and physical parameters. Although radio emission is well studied, planetary nebulae show higher spectral indices than expected for homogeneous sphere.

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.

Radio continuum and CO emission in star-forming galaxies [PDF]
Astronomy & Astrophysics, 2002 We combine the radio continuum images from the NRAO VLA Sky Survey with the CO-line observations from the extragalactic CO survey of the Five College Radio Astronomy Observatory to study the relationship between molecular gas and the star formation rate within the disks of 180 spiral galaxies at 45" resolution. We find a tight correlation between these

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 ...

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

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).

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.

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.
