MWC 656 (=HD 215227) was recently discovered to be the first binary system composed of a Be star and a black hole (BH). We observed it with XMM-Newton, and detected a faint X-ray source compatible with the position of the optical star, thus proving it to be the first Be/BH X-ray binary. The spectrum analysis requires a model fit with two components, a blackbody plus a power law, with keV and a photon index Γ = 1.0 ± 0.8, respectively. The non-thermal component dominates above ≃0.8 keV. The…

The First Simultaneous X-Ray/Radio Detection of the First Be/BH System MWC 656
MWC 656 is the first known Be/black hole (BH) binary system. Be/BH binaries are important in the context of binary system evolution and sources of detectable gravitational waves because they are
Radio Emission from the Be/Black Hole Binary MWC 656
Context. MWC 656 is the recently discovered first binary system case composed of a Be-type star and an accreting black hole. Its low X-ray luminosity indicates that the system is in a quiescent X-ray
THE FIRST LOW-MASS BLACK HOLE X-RAY BINARY IDENTIFIED IN QUIESCENCE OUTSIDE OF A GLOBULAR CLUSTER
The observed relation between the X-ray and radio properties of low-luminosity accreting black holes (BHs) has enabled the identification of multiple candidate black hole X-ray binaries (BHXBs) in
Optical spectroscopy of Be/gamma-ray binaries
We report optical spectroscopic observations of the Be/gamma-ray binaries LSI+61303, MWC 148 and MWC 656. The peak separation and equivalent widths of prominent emission lines (H-alpha, H-beta,
MAGIC observations of MWC 656, the only known Be/BH system
Context. MWC 656 has recently been established as the first observatio nally detected high-mass X-ray binary system containing a Be star and a black hole (BH). The system has been associated with a
A clean sightline to quiescence: multiwavelength observations of the high Galactic latitude black hole X-ray binary Swift J1357.2−0933
We present coordinated multiwavelength observations of the high Galactic latitude (b = +50°) black hole X-ray binary (BHXB) Swift J1357.2−0933 in quiescence. Our broad-band spectrum includes strictly
X-ray spectral and timing properties of the high Mass X-ray binaries GX 304-1 and Vela X-1
Accreting X-ray pulsars are binary systems hosting a rotating, highly magnetized neutron star, and an optical companion star whose expelled plasma is accreted onto the compact object, a process that
The first black hole orbiting a Be star
Stellar-mass black holes have been discovered in binary systems. The study of radial velocities of the companion stars allows us to restrict the masses of the compact objects. The Be/Compact Object
Be X-ray binaries in the SMC as indicators of mass-transfer efficiency
Be X-ray binaries (BeXRBs) consist of rapidly rotating Be stars with neutron star companions accreting from the circumstellar emission disk. We compare the observed population of BeXRBs in the Small
The newly discovered Be/X-ray binary Swift J004516.6–734703 in the SMC: witnessing the emergence of a circumstellar disc
We report on the discovery of Swift J004516.6–734703, a Be/X-ray binary system by the Swift SMC Survey, S-CUBED. Swift J004516.6–734703, or SXP 146.6, was found to be exhibiting a bright (∼1037 erg
