Fierce Feedback in an Obscured, Sub-Eddington State of the Seyfert 1.2 Markarian 817
Miranda K. Zak, Jon M. Miller, Ehud Behar +7
Markarian 817 is a bright and variable Seyfert-1.2 active galactic nucleus (AGN). X-ray monitoring of Mrk 817 with the Neil Gehrels Swift Observatory in 2022 revealed that the sour…
Redshifted iron emission and absorption lines in the Chandra X-ray spectrum of Centaurus A
David Bogensberger, Jon Miller, Elias Kammoun +9
Cen A hosts the closest active galactic nucleus to the Milky Way, which makes it an ideal target for investigating the dynamical processes in the vicinity of accreting supermassive…
The High Energy X-ray Probe (HEX-P): Bringing the Cosmic X-ray Background into Focus
Francesca Civano, Xiurui Zhao, Peter Boorman +29
Since the discovery of the cosmic X-ray background (CXB), astronomers have strived to understand the accreting supermassive black holes (SMBHs) contributing to its peak in the 10-4…
The High Energy X-ray Probe (HEX-P): The Future of Hard X-ray Dual AGN Science
Ryan W. Pfeifle, Peter G. Boorman, Kimberly A. Weaver +15
A fundamental goal of modern-day astrophysics is to understand the connection between supermassive black hole (SMBH) growth and galaxy evolution. Merging galaxies offer one of the…
The High Energy X-ray Probe (HEX-P): The Circum-nuclear Environment of Growing Supermassive Black Holes
P. G. Boorman, N. Torres-Albà, A. Annuar +32
Ever since the discovery of the first Active Galactic Nuclei (AGN), substantial observational and theoretical effort has been invested into understanding how massive black holes ha…
The High Energy X-ray Probe (HEX-P): Sensitive broadband X-ray observations of transient phenomena in the 2030s
Murray Brightman, Raffaella Margutti, Ava Polzin +13
HEX-P will launch at a time when the sky is being routinely scanned for transient gravitational wave, electromagnetic and neutrino phenomena that will require the capabilities of a…
