\begin{abstract} HEX-P is a probe-class mission concept developed by the NASA Jet Propulsion Laboratory (JPL, Pasadena, CA) that will combine high angular resolution ($<5''$ at 6~keV) XXX X-ray ima
To answer NASA's call for a sensitive X-ray observatory in the 2030s, we present the High Energy X-ray Probe (HEX-P) mission concept. HEX-P is designed to provide the required capabilities to explore
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--40 keV band. Existin
