A Parsec-Scale Transient High-Frequency-Peaked Radio Source in the Very Large Array Sky Survey Brightening and Fading over a Decadal Timescale
Yuyang Chen, B. M. Gaensler, Maria R. Drout +10
A subset of active galactic nuclei (AGN) manifests as compact radio sources with peaked radio spectra, commonly referred to as peaked-spectrum (PS) sources. Generally, PS sources a…
First Detection of Radio Polarization During Jet Formation in the Changing-Look AGN 1ES 1927+654
Onic I. Shuvo, Eileen T. Meyer, Sibasish Laha +10
We present a multiwavelength radio study of the changing-look AGN 1ES 1927+654 following its renewed X-ray brightening since mid-2022, combining VLBA imaging with multi-band and ti…
The MegaWave Radio Surveyor
T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40
Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…
A Compact Symmetric Object Discovered by the VLA Low-band Ionosphere and Transient Experiment
Kristina Nyland, Mary Rachelle Barrett, Genna Crom +11
We present new Very Long Baseline Array (VLBA) imaging of a MHz-peaked spectrum (MPS) source that was found using commensal low-frequency data taken with the Karl G. Jansky Very La…
The structure of the giant radio fossil in the Ophiuchus galaxy cluster
Simona Giacintucci, Maxim Markevitch, Tracy Clarke +1
We present high-sensitivity follow-up observations of the giant fossil radio lobe in the Ophiuchus galaxy cluster with the upgraded Giant Metrewave Radio Telescope (uGMRT) in the 1…
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…
Primary Beam Calibration for Commensal Telescopes Utilizing Offset Optics
Emil Polisensky, Tracy E. Clarke, Simona Giacintucci +1
Accurate primary beam calibration is essential for precise brightness measurements in radio astronomy. The VLA Low-band Ionosphere and Transient Experiment (VLITE) faces challenges…
Multi-frequency Radio Observations of the Dissociative Cluster Merger CIZA J0107.7+5408
Emma Schwartzman, Tracy Clarke, Simona Giacintucci +9
We present new radio observations of the galaxy cluster merger CIZA J0107.7+5408 (CIZA0107), a large, roughly equal mass, post-core passage, dissociative binary system at z = 0.106…
The Multi-Epoch Jet Outbursts in Abell 496: synchrotron ageing and buoyant X-ray cavities draped by warm gas filaments
Francesco Ubertosi, Simona Giacintucci, Tracy Clarke +4
The galaxy cluster Abell 496 has been extensively studied in the past for the clear sloshing motion of the hot gas on large scales, but the interplay between the central radio gala…
Probing cluster magnetism with embedded and background radio sources in Planck clusters
Erik Osinga, Reinout J. van Weeren, Lawrence Rudnick +6
Magnetic fields remain an enigmatic part of the content of galaxy clusters. Faraday rotation and depolarisation of extragalactic radio sources are useful probes, but the limited av…
Spectrum and polarization of the Galactic center radio transient ASKAP J173608.2-321635 from THOR-GC and VLITE
Kierra J. Weatherhead, Jeroen M. Stil, Michael Rugel +11
The radio transient ASKAP J173608.2-321735, at the position (l,b)= (356.0872,-0.0390), was serendipitously observed by The HI/OH/Recombination Line Survey of the Galactic Center (T…
A VLITE Search for Millisecond Pulsars in Globular Clusters: Discovery of a Pulsar in GLIMPSE-C01
Amaris V. McCarver, Thomas J. Maccarone, Scott M. Ransom +8
We present results from a search for pulsars in globular clusters, including the discovery of a new millisecond pulsar in the stellar cluster GLIMPSE-C01. We searched for low frequ…
Are radio minihalos confined by cold fronts in galaxy clusters? Minihalos and large-scale sloshing in A3444 and MS 1455.0+2232
