Footprints in the Wind: Probing X-ray Outflows in NGC 7469 using Near-Infrared Emission Lines

Léa M. Feuillet, Steve Kraemer, Anna Trindade Falcão +7

AGN winds play an important role in the co-evolution of supermassive black holes and their host galaxies, yet their driving mechanisms and impact on star formation remain subjects…

JWST/MIRI detection of [Ne V] and [Ne VI] in M83: Evidence for the long sought-after AGN?

Svea Hernandez, Linda J. Smith, Logan H. Jones +16

We report the first detections of [Ne V] 14.3 μm and [Ne VI] 7.7 μm at high confidence (S/N>=6) in the nuclear region of the nearby spiral galaxy M83. Emission line maps of these h…

Core Revelations: the Star Formation and AGN Connection at the Heart of NGC 7469

Léa M. Feuillet, Steve Kraemer, Marcio B. Meléndez +4

We investigate the star formation-AGN connection in the Seyfert 1 NGC 7469 using James Webb Space Telescope (JWST) mid-infrared spectroscopic integral field unit (IFU) data. We use…

A New Radio Loudness Diagnostic for Active Galaxies: a Radio-To-Mid-Infrared Parameter

M. Meléndez, S. B. Kraemer, H. R. Schmitt

We have studied the relationship between the nuclear (high-resolution) radio emission, at 8.4 GHz (3.6 cm) and 1.4 GHz (20 cm), the [O IV] 25.89um, [Ne III] 15.56um and [Ne II] 12.…

New Indicators for AGN Power: The Correlation Between [O IV] lambda 25.89 micron and Hard X-ray Luminosity for Nearby Seyfert Galaxies

M. Meléndez, S. B. Kraemer, B. K Armentrout +7

We have studied the relationship between the [O IV] lambda 25.89 micron emission line luminosities, obtained from Spitzer spectra, the X-ray continua in the 2-10 keV band, primaril…
