AGN winds and outflows: from accretion-disc scales to the host galaxy
Delphine Porquet
Ultra-fast outflows (UFOs), launched from the inner accretion disc in active galactic nuclei (AGN), are among the prime candidates for driving AGN feedback in their host galaxies.…
A possible two-fold scenario for the disc-corona of the luminous AGN 1H 0419--577: a high-density disc or a warm corona
Delphine Porquet, James N. Reeves, Valentina Braito
[abridged] 1H 0419-577 is a highly-accreting, luminous BLS1 AGN. This study aims to characterise its disc-corona system using, for the first time, simultaneous XMM-Newton and NuSTA…
Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A
KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13
High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…
An Eddington Limited Accretion Disk Wind in the narrow line Seyfert 1, PG 1448+273
J. N. Reeves, V. Braito, A. Luminari +5
PG 1448+273 is a luminous, nearby (), narrow line Seyfert 1 galaxy, which likely accretes close to the Eddington limit. Previous X-ray observations of PG 1448 with XMM-Ne…
Active Galaxy Science with the Line Emission Mapper: The Case for High-Resolution Soft X-ray Spectroscopy
Kimberly A. Weaver, Jenna M. Cann, Ryan W. Pfeifle +11
This white paper discusses the breadth of science related to active galactic nuclei (AGN) and associated phenomena to be enabled by a mission with microcalorimeter energy resolutio…
Revealing the burning and soft heart of the bright bare AGN ESO 141-G55: X-ray broadband and SED analysis
Delphine Porquet, James N. Reeves, Scott Hagen +4
[Abridged] ESO 141-G55 is a nearby X-ray bright BLS1, which has been classified as a bare AGN due to the lack of warm absorption along its line-of-sight, providing an unhampered vi…
