Microquasars
A microquasar, a smaller version of a quasar, is a compact region surrounding a stellar black hole with a mass several times that of its Binary star#Cataclysmic variables and X-ray binaries, companion star, observable in sufficient details, in Milky Way, our own or nearby galaxy. The matter being pulled from the companion star forms an accretion disk around the black hole. This accretion disk may become so hot, due to friction, that it begins to emit X-rays. The disk also projects narrow streams or "Astrophysical jet, jets" of subatomic particles at near-Speed of light, light speed, generating a strong radio wave emission. Overview In 1979, SS 433, in our own galaxy, became the first microquasar to be discovered, when Margon et al. observed its relativistic jets. It was thought to be the most exotic case until similar objects such as GRS 1915+105 were confirmed in 1994. In some cases, blobs or "knots" of brighter plasma (physics), plasma within the jets appear to be traveling fast ...
