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…
Gaia GraL: Gaia DR2 Gravitational Lens Systems. VIII. A radio census of lensed systems
Dougal Dobie, Dominique Sluse, Adam Deller +26
We present radio observations of 24 confirmed and candidate strongly lensed quasars identified by the Gaia Gravitational Lenses (GraL) working group. We detect radio emission from…
BASS XLII: The relation between the covering factor of dusty gas and the Eddington ratio in nearby active galactic nuclei
C. Ricci, K. Ichikawa, M. Stalevski +25
Accreting supermassive black holes (SMBHs) located at the center of galaxies are typically surrounded by large quantities of gas and dust. The structure and evolution of this circu…
The High Energy X-ray Probe (HEX-P): Studying Extreme Accretion with Ultraluminous X-ray Sources
Matteo Bachetti, Matthew J. Middleton, Ciro Pinto +25
Ultraluminous X-ray sources (ULXs) represent an extreme class of accreting compact objects: from the identification of some of the accretors as neutron stars to the detection of po…
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): Supernova remnants, pulsar wind nebulae, and nuclear astrophysics
Stephen Reynolds, Hongjun An, Moaz Abdelmaguid +29
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging ( full width at half maximum) and broad spectral coverage (0.2--80 keV) with an…
