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 ( $< 40 Mpc$ ) of hard X-ray selected active galactic nuclei (AGNs) using $4 - 12$ GHz observations with the Karl…

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. 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 $4 - 12$ GHz in-band spectral energy distributions with accompanying 6 GHz and 10 GHz imaging results for a volume-complete sample ( $< 40$ Mpc) of hard X-ray selected activ…
