Deep Search for Gamma-Ray Emission from the Accreting X-Ray Pulsar 1A 0535+262
The Astrophysical Journal, 2023 Binary systems are a well-established subclass of gamma-ray sources. The high mass X-ray binary pulsar 1A 0535+262 has been considered to be a possible gamma-ray emitter for a long time, although former gamma-ray searches using the Fermi Large Area ...

, 2007 With their relatively fast variability time-scales, Galactic X-ray binaries provide an excellent laboratory to explore the physics of accretion and related phenomena, most notably outflows, over different regimes.

Swift J053041.9-665426, a new Be/X-ray binary pulsar in the Large Magellanic Cloud [PDF]
, 2013 We observed the newly discovered X-ray source Swift J053041.9-665426 in the X-ray and optical regime to confirm its proposed nature as a high mass X-ray binary.

X-Ray Binaries in External Galaxies
, 2023 X-ray appearance of normal galaxies is mainly determined by X-ray binaries powered by accretion onto a neutron star or a stellar mass black hole. Their populations scale with the star-formation rate and stellar mass of the host galaxy and their X-ray luminosity distributions show a significant split between star-forming and passive galaxies, both facts

Integral Fluxes of Neutrinos and Gamma-Rays Emitted from Neighboring X-ray Binaries
Universe, 2023 Astrophysical plasma ejections (jets) are formed and powered by black holes that accrete material from their companion star in binary systems. Black hole X-ray binary systems constitute potential powerful galactic and extragalactic neutrino and gamma-ray

A NuSTAR Observation of the Gamma-ray Emitting Millisecond Pulsar PSR J1723-2837 [PDF]
, 2017 We report on the first NuSTAR observation of the gamma-ray emitting millisecond pulsar binary PSR J1723-2837. X-ray radiation up to 79 keV is clearly detected and the simultaneous NuSTAR and Swift spectrum is well described by an absorbed power-law with ...

Constraint on the Accretion of NGC 6946 X-1 Using Broadband X-Ray Data
The Astrophysical Journal, 2023 We analyze broadband X-ray data of NGC 6946 X-1 and probe plausible accretion scenarios in this ULX. NGC 6946 X-1 is a persistent soft source with broadband continuum spectra described by two thermal disk components. The cool accretion disk temperature T

Three New Galactic Center X-ray Sources Identified with Near-Infrared Spectroscopy
, 2013 We have conducted a near-infrared spectroscopic survey of 47 candidate counterparts to X-ray sources discovered by the Chandra X-ray Observatory near the Galactic Center (GC).

Compact Binary X-Ray Sources [PDF]
International Astronomical Union Colloquium, 1986 AbstractCompact binary X-ray sources include white dwarfs, neutron stars, and black holes that are accreting matter from a companion star. The X-ray emission from these systems is produced by the accreting matter as it flows through an accretion disk and strikes the surface of the compact object.
