Abstract

The High-Energy X-ray Probe (HEX-P) is a probe-class mission concept that will extend the reach of broadband (2-200 keV) X-ray observations, with 40 times the sensitivity of any previous mission in the 10-80 keV band and 10,000 times the sensitivity of any previous mission in the 80-200 keV band. HEX-P addresses key NASA science goals and is an important complement to ESA's L-class Athena mission. Working in coordination with Athena HEX-P will provide continuum measurements that are essential for interpreting Athena spectra. With angular resolution improved by more than an order of magnitude relative to NuSTAR, HEX-P will carry out an independent program aimed at addressing questions unique to the high energy X-ray band, such as the nature of the source that powers Active Galactic Nuclei, the evolution of black holes in obscured environments, and understanding of how compact binary systems form, evolve and influence galactic systems. With heritage from NuSTAR, HEX-P can be executed within the next decade with a budget less than double that of a Medium class Explorer (MIDEX) mission.
