Radio Continuum and CO Emission in Star-Forming Galaxies [PDF]

open access: yesAstronomy and 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

Radio Continuum Emission From a Tidal Dwarf Galaxy [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society
ABSTRACT Tidal dwarf galaxies (TDGs) form in the debris of galaxy mergers, making them ideal testbeds for investigating star formation in an extreme environment. We present radio continuum EVLA observations spanning 1–2 GHz of the interacting system Arp 94, which contains the TDG J1023+1952.

Radio Continuum Spectra of Planetary Nebulae

open access: yesGalaxies, 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]

open access: yesSerbian 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 Emission From Knots in the DG Tauri Jet [PDF]

open access: yesAstronomy and 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.

On the integrated continuum radio spectrum of supernova remnant W44 (G34.7-0.4): New insights from Planck [PDF]

open access: yesSerbian Astronomical Journal, 2015
In this paper, the integrated continuum radio spectrum of supernova remnant (SNR) W44 was analyzed up to 70 GHz, testing the different emission models that can be responsible for its particular shape.

An Ionized Outflow in Orion-KL Source I?

open access: yesThe Astrophysical Journal, 2023
We present images at 6 and 14 GHz of Source I (SrcI) in the Kleinmann–Low Nebula in Orion. At higher frequencies, from 43 to 340 GHz, images of this source are dominated by thermal emission from dust in a 100 au diameter circumstellar disk, but at 6 and ...

Radio Continuum Emission from the Magellanic Clouds [PDF]

open access: yesSymposium - International Astronomical Union, 1991
New radio continuum surveys of the Large and the Small Magellanic Cloud have been completed recently at four frequencies, using the Parkes 64-m telescope. Here we shall discuss briefly the overall radio morphology of the Clouds at different frequencies and discuss the detected linear polarization.

H i 21 cm Extended Structures to the Northeast and Southwest of NGC 5595: VLA Observations of the Disk Galaxy Pair NGC 5595 and NGC 5597

open access: yesThe Astronomical Journal, 2023
We report VLA B-configuration observations of the H i 21 cm line on the close disk galaxy pair NGC 5595 and NGC 5597. At the angular resolution of the observations, ∼7.″1 × 4.″2, while most of the H i 21 cm in NGC 5595 and NGC 5597 has the same extent as

First Detection of Radio Emission Associated with a Classical Cepheid

open access: yesThe Astronomical Journal, 2023
We report the detection of 15 GHz radio continuum emission associated with the classical Cepheid variable star δ Cephei ( δ Cep) based on observations with the Karl G. Jansky Very Large Array.
