Flat Spectrum Radio Continuum Emission Associated with $ε$ Eridani [PDF]

open access: greenThe 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

Observations of radio continuum emission from M31 [PDF]

open access: bronzeSymposium - 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.

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.

Revisiting the Group-dominant Elliptical NGC 5044 in the Radio Band: Continuum Emission and Detection of H i Absorption [PDF]

open access: greenThe Astrophysical Journal
We present new MeerKAT L -band (continuum and H i ) and upgraded Giant Metrewave Radio Telescope (300–850 MHz) observations of the archetypal cool-core group-dominant early-type galaxy NGC 5044. Our new continuum images reveal diffuse, steep spectrum ( ${

Radio continuum emission from the Magellanic Clouds [PDF]

open access: bronzeSymposium - 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.

Radio Continuum Emission from FS CMa Stars [PDF]

open access: green, 2011
The FS CMa stars exhibit bright optical emission-line spectra and strong IR excesses. Very little is known of their radio characteristics. We analyzed archive Very Large Array data to search for radio continuum emission in a sample of them. There are good quality data for seven of the $\sim$40 known FS CMa stars.

Characterizing the radio continuum emission from intense starburst galaxies [PDF]

open access: greenMonthly Notices of the Royal Astronomical Society, 2016
The intrinsic thermal (free-free) and non-thermal (synchrotron) emission components that comprise the radio-continuum of galaxies represent unique, dust-free measures of star formation rates (SFR). Such high SFR galaxies will dominate the deepest current and future radio surveys.

MULTI-WAVELENGTH RADIO CONTINUUM EMISSION STUDIES OF DUST-FREE RED GIANTS [PDF]

open access: bronzeThe Astronomical Journal, 2013
Multi-wavelength centimeter continuum observations of non-dusty, non-pulsating K spectral-type red giants directly sample their chromospheres and wind acceleration zones. Such stars are feeble emitters at these wavelengths however, and previous observations have provided only a small number of modest S/N measurements slowly accumulated over three ...

Radio continuum emission from a tidal dwarf galaxy [PDF]

open access: goldMonthly 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.
