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…
A dichotomy in the 1-24 GHz parsec-scale radio spectra of radio-quiet quasars
Sina Chen, Ari Laor, Ehud Behar +3
We present the pc-scale radio spectra of a representative sample of 13 Palomar-Green radio-quiet quasars, based on our new Very Long Baseline Array (VLBA) observations at 8.4 and 2…
VLASS-based survey of transition state galaxies and their relationship to compact peaked-spectrum radio sources
M. Kunert-Bajraszewska, A. Krauze, A. E. Kimball +6
We present multi-frequency and high-resolution studies of a sample of 24 radio transients sources discovered by comparing the NRAO VLA Sky Survey (NVSS) and Very Large Array Sky Su…
Windy or not: Radio pc-scale evidence for a broad-line region wind in radio-quiet quasars
Sina Chen, Ari Laor, Ehud Behar +6
Does a broad-line region (BLR) wind in radio-quiet (RQ) active galactic nuclei (AGN) extend to pc scales and produce radio emission? We explore the correlations between a pc-scale…
