Microquasars are X-ray binaries with relativistic jets. These jets are powerful energy carriers—
thought to be fed by accretion—which produce nonthermal emission at different energy …

(abridged) The review describes observations of SS433. The main difference between
SS433 and other X-ray binaries is the supercritical regime for the gas accretion onto the …

SS 433 is a binary system containing a supergiant star that is overflowing its Roche lobe
with matter accreting onto a compact object (either a black hole or neutron star),–. Two jets …

We present VLA images at 327.5 and 1465 MHz of the nebula W50 surrounding the stellar
source of relativistic jets SS 433. At 1.4 GHz, we have produced an image of W50 with an …

We present high-resolution radio studies at 1.47 and 4.79 GHz, made with the Australia
Telescope, which show clear evidence for jet-like structure within the nebula surrounding Cir …

We report the observations of the X-ray lobes of the large Galactic source W50 associated
with the two-sided jets source SS 433. The observations were made with the Position …

Observations of the highly Doppler shifted emission lines in SS 433 have now been
obtained over a period of 10 years, and some inferences available from this data base are …

New photoelectric B, V observations carried out in 1980 February–June have shown that SS
433 appears to be an eclipsing binary system with orbital period 13.09±0.04 day, which …

We present the results from a series of X-ray observations of SS433 made with the EXOSAT
Observatory in 1983–85 which show that strong iron line emission is present in its X-ray …

How black holes are formed remains an open and fundamental question in astrophysics.
Despite theoretical predictions, it lacks observations to understand whether the black hole …
