Latest Relativistic jet Stories
NASA astronomers have found evidence of two supermassive black holes at the center of a remote galaxy that are locked in a fierce, circling dance.
Black holes are voracious monsters at the center of galaxies that shape the growth and death of the stars around them with their tremendous gravitational pull and explosive ejections of energy. Now, researchers are using them as a tool to probe the limits of spacetime.
According to new research, the flash from one of the biggest and brightest bangs ever recorded by astronomers is derived from a massive black hole at the center of a distant galaxy.
WASHINGTON, May 20, 2011 /PRNewswire-USNewswire/ -- An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere, has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.

Scientists have found evidence that a giant black hole has been jerked around twice, causing its spin axis to point in a different direction from before.
NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole.
A survey by the Chandra X-ray observatory has revealed in detail, for the first time, the effects of a shock wave blasted through a galaxy by powerful jets of plasma emanating from a supermassive black hole at the galactic core.
A flare-up in a jet of matter blasting from a monster black hole is giving astronomers an incredible light show.
Astronomers have a new insight into the active galaxy Centaurus A (NGC 5128), as the jets and lobes emanating from the central black hole have been imaged at submillimeter wavelengths for the first time.
Microquasar -- Microquasars are smaller cousins of quasars. They are named after quasars, as they have some common characteristics: strong and variable radio emission often seen as radio jets, and an accretion disk surrounding a black hole. In quasars, the black hole is supermassive (millions of solar masses) as in microquasars, the black hole mass is a few solar masses. In microquasars, the accreted mass comes from a normal star and the accretion disk is very luminous in optical regions...
