The High Energy X-ray Probe (HEX-P)

HEX-P is a Probe-class mission concept that will combine high spatial resolution X-ray imaging (<10 arcsec FWHM) and broad spectral coverage (0.1-150 keV) with an effective area far superior to current facilities (including XMM-Newton and NuSTAR), to enable revolutionary new insights into a variety of important astrophysical problems. With this leap in observational capability, HEX-P will be capable of addressing fundamental questions about the extreme environments around black holes and neutron stars, map the growth of supermassive black holes, and quantify the effect they have on their environments. HEX-P will resolve the hard X-ray emission from dense regions of our Galaxy and nearby galaxies to understand the high-energy source populations, and investigate dark matter candidate particles through their decay channel signatures. We present the baseline mission design and core science pillars. More information on HEX-P, including the full team list, is available at https://hexp.org.
