Relativistic reflection features are commonly observed in the X-ray spectra of accreting black
holes. In the presence of high quality data and with the correct astrophysical model, X-ray …

We extend our recent work on black hole spin in X-ray binary systems to include an analysis
of 189 archival NuSTAR observations from 24 sources. Using self-consistent data reduction …

The launch of NuSTAR and the increasing number of binary black hole (BBH) mergers
detected through gravitational wave observations have exponentially advanced our …

Einstein's theory of General Relativity predicts that the spacetime metric around
astrophysical black holes is described by the Kerr solution. In this work, we employ state-of …

We present the broad-band spectral analysis of all the six hard, intermediate, and soft state
NuSTAR observations of the recently discovered transient black hole X-ray binary MAXI …

Our Galactic center contains young stars, including the few million year-old clockwise disk
between 0.05 and 0.5 pc from the Galactic center and the S-star cluster of B-type stars at a …

We present an investigation of the quiescent and transient X-ray binaries (XRBs) of the
Galactic Center (GC). We extended our Chandra analysis of the non-thermal X-ray sources …

HEX-P is a probe-class mission concept that will combine high spatial resolution X-ray
imaging (< 1 0 ″FWHM) and broad spectral coverage (0.2–80 keV) with an effective area …

Context. Molecular clouds in the Galactic center (GC) reprocess radiation from past
outbursts of nearby high-energy sources, generating a bright Fe Kα fluorescence at 6.4 keV …

We extend our recent work on black hole spin in X-ray binary systems to include an analysis
of 189 archival NuSTAR observations from 24 sources. Using self-consistent data reduction …
