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…
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…
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…
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…
