With the advent of more sensitive all-sky instruments, the transient universe is being probed
in greater depth than ever before. Taking advantage of available resources, we have …

We present a new edition of the catalogue of high-mass X-ray binaries in the Galaxy. The
catalogue contains source name (s), coordinates, finding chart, X-ray luminosity, system …

This book deals with the fundamentals of stellar interferometry with emphasis on aperture
synthesis using sparse array of telescopes particularly at optical/IR wavelengths, the origin …

Microquasar SS433 is composed by a supergiant star that feeds mass through a
supercritical accretion disk to a∼ 10 M⊙ black hole. The latter launches two oppositely …

The Galactic microquasar SS433 launches oppositely directed plasma jets at speeds
approximately a quarter of the speed of light along an axis which precesses, tracing out a …

The fastest pulsar and the slowest nova; the oldest galaxies and the youngest stars; the
weirdest life forms and the commonest dwarfs; the highest energy particles and the lowest …

A common consequence of accretion onto black holes is the formation of powerful,
relativistic jets that escape the system. In the case of supermassive black holes at the …

We obtained a broadband radio spectrum of the galactic compact object SS433 through the
multi-wavelength campaign using the Giant Meter Radio Telescope (GMRT) and the …

Aims. Our aim in this paper is to discover the spectral characteristics of the enigmatic
compact object SS433 during a very rare occasion when the blue jet was pointing towards …

We study the multi-wavelength spectral properties of the black hole X-ray binary MAXI J1348–
630 using quasi-simultaneous ALMA, NICER, and Swift observations during the decay …
