First Detection of the Doppler Shift of X-ray Photons Due to a Telescope's Orbital Motion

Stephen DiKerby, Shuo Zhang

We have detected for the first time the redshifting and blueshifting of X-ray photons due to the orbital motion of an X-ray telescope around the Earth. Current and planned X-ray te…

The very faint X-ray transient Swift J174610-290018 at the Galactic center

Giovanni Stel, Gabriele Ponti, Nathalie Degenaar +17

Very Faint X-ray Transients (VFXTs) are a class of X-ray binary systems that exhibit occasional outbursts with peak X-ray luminosities (L_X< 1e36 erg s^-1) much lower than typical…

Multiwavelength observation of a candidate pulsar halo LHAASO J0621+3755 and the first X-ray detection of PSR J0622+3749

C. B. Adams, A. Archer, P. Bangale +71

Pulsar halos are regions around middle-aged pulsars extending out to tens of parsecs. The large extent of the halos and well-defined central cosmic-ray accelerators make this new c…

Fifteen Years of M31* X-ray Variability and Flares

Stephen DiKerby, Shuo Zhang, Jimmy Irwin

We append an additional fifteen years (2009-2024) to the Chandra X-ray light curve of M31*, the supermassive black hole at the center of M31, the Andromeda galaxy. Extending and ex…

The High Energy X-ray Probe (HEX-P): resolving the nature of Sgr A* flares, compact object binaries and diffuse X-ray emission in the Galactic Center and beyond

Kaya Mori, Gabriele Ponti, Matteo Bachetti +24

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