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…
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…
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…
Searching for Radio Transients with Inverted Spectra in Epoch 1 of VLASS and VCSS, and Identification of a Sample of Candidate Relativistic Nuclear Transients
Yuyang Chen, B. M. Gaensler, Tracy Clarke +3
For radio transients, an inverted spectrum (defined as for a power law spectrum ) constrains physical properties, which in principle can be a useful criterio…
Unstable phenomena in stable magnetospheres: searching for radio flares from magnetic OBA stars using VCSS
E. Polisensky, B. Das, W. Peters +3
Although the majority of hot magnetic stars have extremely stable, kG strength surface magnetic fields with simple topologies, a subset undergo small-scale explosions due to…
A candidate relativistic tidal disruption event at 340 Mpc
Jean J. Somalwar, Vikram Ravi, Dillon Z. Dong +13
We present observations of an extreme radio flare, VT J024345.70-284040.08, hereafter VT J0243, from the nucleus of a galaxy with evidence for historic Seyfert activity at redshift…
Radio Spectra of Luminous, Heavily Obscured WISE-NVSS Selected Quasars
Pallavi Patil, Mark Whittle, Kristina Nyland +12
We present radio spectra spanning GHz for the sample of heavily obscured luminous quasars with extremely red mid-infrared-optical colors and compact radio emission. The…
Quasars That Have Transitioned from Radio-quiet to Radio-loud on Decadal Timescales Revealed by VLASS and FIRST
Kristina Nyland, Dillon Z. Dong, Pallavi Patil +21
We have performed a search over 3440 deg of Epoch 1 (2017-2019) of the Very Large Array Sky Survey to identify unobscured quasars in the optical () and obscured…
Variable Radio AGN at High Redshift Identified in the VLA Sky Survey
Kristina Nyland, Dillon Dong, Pallavi Patil +11
As part of an on-going study of radio transients in Epoch 1 (2017-2019) of the Very Large Array Sky Survey (VLASS), we have discovered a sample of 0.2<z<3.2 active galactic nuclei…
