A Radio Flaring, Chromospherically-Inactive K Dwarf
Dale A. Frail, Scott D. Hyman, Michele L. Silverstein +10
We report on an unusual radio source J180526-292953, initially identified as a steep spectrum, polarized point source toward the Galactic bulge and found to coincide with the nearb…
An Image-Based Search for Pulsar Candidates in the MeerKAT Bulge Survey
Dale A. Frail, Emil Polisensky, Scott D. Hyman +13
We report on the results of an image-based search for pulsar candidates toward the Galactic bulge. We used mosaic images from the MeerKAT radio telescope, that were taken as part o…
One size fits all: Insights on Extrinsic Thermal Absorption from Similarity of Supernova Remnant Radio Continuum Spectra
M. G. Abadi, G. Castelletti, L. Supan +2
Typically, integrated radio frequency continuum spectra of supernova remnants (SNRs) exhibit a power-law form due to their synchrotron emission. In numerous cases, these spectra sh…
Thermal radio absorption as a tracer of the interaction of SNRs with their environments
G. Castelletti, L. Supan, W. M. Peters +1
We present new images and continuum spectral analysis for 14 resolved Galactic SNRs selected from the 74 MHz Very Large Array Low-Frequency Sky Survey Redux (VLSSr). We combine new…
Origin of the ring structures in Hercules A -- Sub-arcsecond 144 MHz to 7 GHz observations
R. Timmerman, R. J. van Weeren, J. R. Callingham +18
The prominent radio source Hercules A features complex structures in its radio lobes. Although it is one of the most comprehensively studied sources in the radio sky, the origin of…
Two Extreme Steep-Spectrum, Polarized Radio Sources Towards the Galactic Bulge
S. D. Hyman, D. A. Frail, J. S. Deneva +8
From an on-going survey of the Galactic bulge, we have discovered a number of compact, steep spectrum radio sources. In this present study we have carried out more detailed observa…
