The existing radio and X-ray flux correlation for Galactic black holes in the hard and
quiescent states relies on a sample which is mostly dominated by two sources (GX 339− 4 …

We report on a first census of Galactic black hole X-ray binary (BHXRB) properties with the
second data release (DR2) of Gaia, focusing on dynamically confirmed and strong …

In X-ray binaries, compact jets are known to commonly radiate at radio to infrared
frequencies, whereas at optical to γ-ray energies, the contribution of the jet is debated. The …

Many X-ray binaries remain undetected in the mid-infrared, a regime where emission from
their compact jets is likely to dominate. Here, we report the detection of the black hole binary …

Cygnus X–1 is the first Galactic source confirmed to host an accreting black hole. It has been
detected across the entire electromagnetic spectrum from radio to GeV gamma-rays. The …

We studied the polarization properties of Cygnus X–1 in both hard and soft spectral states
with imaging X-ray polarimetry explorer (IXPE) observations. The polarization degree is, and …

Galactic black hole binaries produce powerful outflows which emit over almost the entire
electromagnetic spectrum. Here, we report the first detection with the Herschel observatory …

ABSTRACT Polarization of the $\gtrsim 400$ keV hard tail of the microquasar Cygnus X-1
has been independently reported by INTEGRAL/Imager on Board the INTEGRAL Satellite …

We apply the jet model developed in the preceding paper of Zdziarski et al. to the hard-state
emission spectra of Cyg X-1. We augment the model for the analytical treatment of the …

An internal shock model is proposed to interpret the radio to infrared (IR) emission of the
compact jets observed in the hard spectral state of X-ray binaries. Assuming that the specific …
