Very Long Baseline Interferometry Search for Nuclear Radio Continuum Emission in the Barred Spiral Galaxy NGC 7479
Seppo Laine, Emmanuel Momjian, Emilia Järvelä +4
We have obtained very high angular resolution (a few milliarcseconds or sub-parsec scale) Very Long Baseline Array (VLBA) and European Very Long Baseline Interferometry (VLBI) Netw…
The UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Large Director's Discretionary Program with Hubble. I. Goals, Design, and Initial Results
Julia Roman-Duval, William J. Fischer, Alexander W. Fullerton +44
Specifically selected to leverage the unique ultraviolet capabilities of the Hubble Space Telescope, the Hubble Ultraviolet Legacy Library of Young Stars as Essential Standards (UL…
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…
Hubble Space Telescope Observations of Nearby Type 1 Quasars. I. Characterisation of the Extended [O III] 5007Å Emission
Anna Trindade Falcão, S. B. Kraemer, T. C. Fischer +13
We use the Hubble Space Telescope to analyse the extended [O III] 5007A emission in seven bright radio-quiet type 1 quasars (QSO1s), focusing on the morphology and physical conditi…
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…
Star Formation Rates in [Ne V] 3426 Å Selected Active Galactic Nuclei: Evidence for a Decrease along the Main Sequence?
Léa Feuillet, Marcio Meléndez, Steve Kraemer +3
Studying the behavior along the galaxy main sequence is key in furthering our understanding of the possible connection between AGN activity and star formation. We select a sample o…
Classifying Intermediate Redshift Galaxies in SDSS: Alternative Diagnostic Diagrams
Léa Feuillet, Marcio Meléndez, Steve Kraemer +3
We select a sample of 1,437 active galactic nuclei (AGN) from the catalog of the Sloan Digital Sky Survey (SDSS) galaxy properties from the Portsmouth group by detection of the hig…
Mass Outflow of the X-ray Emission Line Gas in NGC 4151
S. B. Kraemer, T. J. Turner, J. D. Couto +4
We have analysed Chandra/High Energy Transmission Gratings spectra of the X-ray emission line gas in the Seyfert galaxy NGC 4151. The zeroth order spectral images show extended H-…
