First Detection of an Ultracool Dwarf at 340 MHz: VLITE Observations of EI Cancri AB
Michele L. Silverstein, Tracy E. Clarke, Wendy M. Peters +3
Magnetically driven phenomena such as flaring events and aurorae lead ultracool dwarfs to emit at radio frequencies. Despite decades of scrutiny, a comprehensive physical understan…
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…
Radio Emission from the Infrared Tidal Disruption Event WTP14adeqka: The First Directly Resolved Delayed Outflow from a TDE
Walter W. Golay, Edo Berger, Yvette Cendes +10
We present detailed radio observations of the mid-infrared (MIR) tidal disruption event (TDE) WTP14adeqka. We detect rising radio emission starting years after the disc…
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…
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 crit…
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…
