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…

Time-evolving diagnostic of the ionized absorbers in NGC 4051. I. High-resolution time-averaged spectroscopy

Roberto Serafinelli, Fabrizio Nicastro, Alfredo Luminari +6

We present a high-resolution X-ray spectroscopic study of the Narrow-Line Seyfert 1 galaxy NGC 4051 using two XMM-Newton high-resolution Reflection Grating Spectrometer (RGS) obser…

High Resolution (<100pc) Ionization Structures in the ISM of AGN ESO~137-G34

D. Ł. Król, G. Fabbiano, M. Elvis +8

We present a detailed, spatially resolved { Veilleux \& Osterbrock (VO) diagram} analysis of ESO\,137-G034, a Compton-thick Active Galactic Nucleus (AGN), based on narrowband {\it…

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)…

The WISSH quasar project. XII. X-ray view of the most luminous quasi-stellar objects at Cosmic Noon

C. Degli Agosti, C. Vignali, E. Piconcelli +25

To improve our knowledge of nuclear emission in luminous QSOs at Cosmic Noon, we studied the X-ray emission of the WISE/SDSS-selected hyper-luminous (WISSH) QSO sample: 85 broad-li…

X-ray view of a massive node of the Cosmic Web at z=3 II. Discovery of extended X-ray emission around a hyperluminous QSO

Andrea Travascio, Sebastiano Cantalupo, Gabriele Pezzulli +17

While the warm, ionized gas in the CGM at z>3 is now routinely observed around bright QSOs in Lya emission, little is known about the CGM hot phase due to its expected faintness in…

Mapping the Excitation Mechanisms in the LINER I Active Galactic Nucleus NGC 5005: Positive Feedback and a Thin LINER Cocoon

Anna Trindade Falcão, G. Fabbiano, M. Elvis +5

We present a spatially resolved Baldwin-Phillips-Terlevich analysis of the narrow-line region (NLR) in the low-ionization nuclear emission-line region (LINER) I galaxy NGC 5005 usi…

XMM/HST monitoring of the ultra-soft highly accreting Narrow Line Seyfert 1 RBS 1332

R. Middei, S. Barnier, F. G. Saturni +10

Ultra-soft narrow line Seyfert 1 (US-NLSy) are a poorly observed class of active galactic nuclei characterized by significant flux changes and an extreme soft X-ray excess. This pe…
