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…

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…

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)…

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…

Hubble Space Telescope Observations of Nearby Type 1 Quasars. I. Characterisation of the Extended [O III] 5007Ã 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…
