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…

Hot, Photoionized X-ray Gas in Two Luminous Type 2 Quasars: Chandra-HST Evidence for a Wind-Driven Sequence

Anna Trindade Falcão, S. Kraemer, L. Feuillet +17

We present new Chandra/ACIS-S imaging spectroscopy of two luminous type 2 quasars, FIRST J120041.4+314745 (=0.116) and 2MASX J13003807+5454367 (=0.088), and compare their X-r…

The X-ray Emission of NGC 5005: An Unobscured Low-Luminosity AGN with a Weakly Accreting Broad-Line Region

Anna Trindade Falcão, R. Middei, G. Fabbiano +5

We present deep Chandra X-ray observations of NGC 5005, a LINER-dominated galaxy previously reported to host a broad H emission line. The diffuse soft X-ray emission (3 keV)…

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…

Resolving Dual Active Galactic Nuclei with ~100 pc separation in MCG-03-34-64

Anna Trindade Falcao, T. J. Turner, S. B. Kraemer +4

We report the serendipitous multiwavelength discovery of a candidate dual black hole system with a separation of ~100 pc, in the gas-rich luminous infrared galaxy MCG-03-34-64 (z=0…

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…
