The High Energy X-ray Probe (HEX-P): Probing Accretion onto Stellar Mass Black Holes
Riley Connors, John Tomsick, Paul Draghis +20
Accretion is a universal astrophysical process that plays a key role in cosmic history, from the epoch of reionization to galaxy and stellar formation and evolution. Accreting stel…
The High Energy X-ray Probe (HEX-P): Constraining Supermassive Black Hole Growth with Population Spin Measurements
J. M. Piotrowska, J. A. García, D. J. Walton +24
Constraining the primary growth channel of supermassive black holes (SMBH) remains one the most actively debated questions in the context of cosmological structure formation. Owing…
Variability as a predictor for the hard-to-soft state transition in GX 339-4
Matteo Lucchini, Marina Ten Have, Jingyi Wang +17
During the outbursts of black hole X-ray binaries (BHXRBs), their accretion flows transition through several states. The source luminosity rises in the hard state, dominated by non…
The eROSITA Final Equatorial Depth Survey (eFEDS): Complex absorption and soft excesses in hard X-ray--selected active galactic nuclei
Sophia G. H. Waddell, Kirpal Nandra, Johannes Buchner +14
Context. The soft excess, a surplus of X-ray photons above 2 keV with respect to a power law, is a feature of debated physical origin found in the X-ray spectra of many type-1 acti…
Investigating the impact of vertically extended coronae on X-ray reverberation mapping
Matteo Lucchini, Guglielmo Mastroserio, Jingyi Wang +9
Accreting black holes commonly exhibit hard X-ray emission, originating from a region of hot plasma near the central engine referred to as the corona. The origin and geometry of th…
Vacuum polarization alters the spectra of accreting X-ray pulsars
E. Sokolova-Lapa, J. Stierhof, T. Dauser +1
It is a common belief that for magnetic fields typical for accreting neutron stars in High-Mass X-ray Binaries vacuum polarization only affects the propagation of polarized emissio…
