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 …

In recent years, much effort has been devoted to unravelling the connection between the
accretion flow and the jets in accreting compact objects. In the present work, we report new …

The radio/X-ray correlation for hard and quiescent state black hole X-ray binaries is critically
investigated in this paper. New observations of known sources, along with newly discovered …

Most transient black hole X-ray binaries (BHXBs) spend the bulk of their time in a quiescent
state, where they accrete matter from their companion star at highly sub-Eddington …

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 …

The transitional millisecond pulsar (MSP) binary system PSR J1023+ 0038 re-entered an
accreting state in 2013 June in which it bears many similarities to low-mass X-ray binaries …

MAXI J1659− 152 is a bright X-ray transient black-hole candidate binary system discovered
in September 2010. We report here on MAXI, RXTE, Swift, and XMM-Newton observations …

Multiwavelength observations of Galactic black hole transients have opened a new path to
understanding the physics of the innermost parts of the accretion flows. While the processes …

We have analysed the NRAO Very Large Array Sky Survey and Sydney University Molonglo
Sky Survey data at 1.4 GHz and 843 MHz for a well-defined complete sample of hard X-ray …

The determination of mass and spin parameters of the black holes (BHs) is crucial in the
analysis of the merger of BHs and BHs formation and evolution, including accretion. Here …
