CHILLING: Continuum Halos in LVHIS Local Irregular Nearby Galaxies - Radio continuum spectral behavior of dwarf galaxies
Sam Taziaux, Megan C. Johnson, Onic I. Shuvo +13
Dwarf galaxies, due to their shallow gravitational potentials, provide critical environments for studying feedback mechanisms from star formation and its impacts on dwarf galaxy ev…
VLA FRAMEx. III. Circumnuclear Radio Emission Mechanisms in Hard X-ray Selected Active Galactic Nuclei
Andrew J. Sargent, Alexander J. van der Horst, Megan C. Johnson +5
We present Stokes I continuum analysis for a volume-limited sample () of hard X-ray selected active galactic nuclei (AGNs) using GHz observations with the Karl…
VLA FRAMEx. II. Radio Spectra of Nearby Active Galactic Nuclei at Subarcsecond Resolution
Andrew J. Sargent, Alexander J. van der Horst, Megan C. Johnson +5
We present GHz in-band spectral energy distributions with accompanying 6 GHz and 10 GHz imaging results for a volume-complete sample ( Mpc) of hard X-ray selected activ…
FRAMEx. V. Radio Spectral Shape at Central Sub-parsec Region of AGNs
Onic I. Shuvo, Megan C. Johnson, Nathan J. Secrest +4
We present results from the Very Long Baseline Array (VLBA) multi-frequency (1.6, 4.4, 8.6, 22 GHz), high-sensitivity (~25 microJy beam^-1), sub-parsec scale (<1 pc) observations a…
VLA FRAMEx. I. Wideband Radio Properties of the AGN in NGC 4388
Andrew J. Sargent, Travis C. Fischer, Megan C. Johnson +5
We present the first results from Karl G. Jansky Very Large Array (VLA) observations as a part of the Fundamental Reference Active Galactic Nucleus (AGN) Monitoring Experiment (FRA…
FRAMEx IV: Mechanical Feedback from the Active Galactic Nucleus in NGC 3079
Luis C. Fernandez, Nathan J. Secrest, Megan C. Johnson +1
Using the Very Long Baseline Array, we observed the active galactic nucleus (AGN) in NGC 3079 over a span of six months to test for variability in the two main parsec-scale radio c…
