Daniel Stern, 2023, "The High Energy X-ray Probe (HEX-P): Probing the physics of the X-ray corona in active galactic nuclei", https://doi.org/10.48577/jpl.UVNCMJ, Frontiers of Astronomy and Space Sciences, JPL Open Repository
The hard, non-thermal X-ray emission in active galactic nuclei (AGN) and black hole X-ray binaries (BHXRBs) is traditionally thought to be produced by a hot cloud of electrons referred to as the corona, which resides in close vicinity to the central black hole. This emission is c... |

Daniel Stern, 2023, "The High Energy X-ray Probe (HEX-P): Magnetars and Other Isolated Neutron Stars", https://doi.org/10.48577/jpl.BBLHOG, Frontiers in Astronomy and Space Sciences, JPL Open Repository
The hard X-ray emission from magnetars and other isolated neutron stars remains under- explored. An instrument with higher sensitivity to hard X-rays is critical to understanding the physics of neutron star magnetospheres and also the relationship between magnetars and Fast Radio... |

Daniel Stern, 2023, "The High Energy X-ray Probe (HEX-P): resolving the nature of Sgr A* flares, compact object binaries, ultra-relativistic cosmic-rays and particle accelerators in the Galactic Center", https://doi.org/10.48577/jpl.BCST9N, Frontiers in Astronomy and Space Sciences, JPL Open Repository
HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray imaging (< 10′′ FWHM) and broad spectral coverage (0.2–80 keV) with a sensitivity far superior to current facilities (including XMM-Newton and NuSTAR). These capabilities will enable revolution... |

Daniel Stern, 2023, "The High Energy X-ray Probe (HEX-P): Studying Extreme Accretion with Ultraluminous X-ray Sources", https://doi.org/10.48577/jpl.3AYAGF, Frontiers in Astronomy and Space Sciences, JPL Open Repository
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 powerful winds travelling at 0.1-0.2 c, the increasing evidence points towards ULXs harbouring stellar... |
