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.

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.

Broadband VLA Spectral-line Survey of a Sample of Ionized Jet Candidates

The Astrophysical Journal Supplement Series, 2023
The study of the interaction between ionized jets, molecular outflows, and their environments is critical to understanding high-mass star formation, especially because jets and outflows are thought to be key in the transfer of angular momentum outward ...

Flat-spectrum Radio Continuum Emission Associated with ϵ Eridani [PDF]

The Astrophysical Journal, 2019
Abstract We present Very Large Array observations at 33.0 GHz that detect emission coincident with ϵ Eridani to within 0.″07 (0.2 au at the distance of this star), with a positional accuracy of 0.″05. This result strongly supports the suggestion of previous authors that the quiescent centimeter emission comes from the star and not from a

VLT spectropolarimetry of two powerful radio galaxies at z~1.4: UV continuum, emission-line properties and the nature of high-redshift dust

, 2004
(Abridged) Deep VLT spectropolarimetric observations are presented for two powerful radio galaxies, 0850-206 and 1303+091. These observations cover the rest-frame wavelength range ~ 1450 - 3750 A.

Radio continuum emission from knots in the DG Tauri jet [PDF]

Astronomy & Astrophysics, 2012
Context: HH 158, the jet from the young star DG Tau, is one of the few sources of its type where jet knots have been detected at optical and X-ray wavelengths. Aims: To search, using Very Large Array observations of this source, radio knots and if detected, compare them with the optical and X-ray knots.

A global view on star formation: The GLOSTAR Galactic plane survey

Astronomy & Astrophysics
Context. Extended radio continuum emission and its linear polarization play a key role in probing large-scale structures of synchrotron and free-free emission in the Milky Way.

Sensitive Radio Observations of High Redshift Dusty QSOs [PDF]

, 1999
We present sensitive radio continuum imaging at 1.4 GHz and 4.9 GHz of seven high redshift QSOs selected for having a 240 GHz continuum detection, which is thought to be thermal dust emission.

RADIO CONTINUUM EMISSION AND WATER MASERS TOWARD CB 54 [PDF]

The Astronomical Journal, 2009
We present high angular resolution observations of water masers at 1.3 cm and radio continuum emission at 1.3, 3.6 and 6 cm towards the Bok globule CB 54 using the Very Large Array. At 1.3 cm, with subarsecond angular resolution, we detect a radio continuum compact source located to the south-west of the globule and spatially coincident with a mid ...
