A student astronomer may have pinpointed one of the universe's most dramatic events for the first time - a so-called "supermassive" black hole being hurled out of a galaxy.

In pictures, the object discovered by Marianne Heida, looks like nothing more than a speck of light on the edge of a swirling cloud.
But the unassuming shape is thought to be a giant black hole, more than a billion times the mass of the sun, flying at 670,000 miles per hour through space.
Miss Heida, a student at Utrecht University in the Netherlands, made the discovery as part of a final-year project.

Black hole 'hurled out of galaxy'

A supermassive black hole may have been observed in the process of being hurled from its parent galaxy at high speed.
The finding comes from analysis of data collected by the US Chandra space X-ray observatory.
However, there are alternative explanations for the observation.

Title: A bright off-nuclear X-ray source: A bright off-nuclear X-ray source: a type IIn supernova, a bright ULX or a recoiling super-massive black hole in CXO J122518.6+144545
Authors: P.G. Jonker, M.A.P. Torres, A.C. Fabian, M. Heida, G. Miniutti, D. Pooley

In this Paper we report the discovery of CXO J122518.6+144545; a peculiar X-ray source with a position 3.6±0.2",off-nuclear from an SDSS DR7 z=0.0447 galaxy. The 3.6" offset corresponds to 3.2 kpc at the distance of the galaxy. The 0.3-8 keV X-ray flux of this source is 5x10^-14 erg cm^-2 s^-1 and its 0.3-8 keV luminosity is 2.2x10^41 erg/s (2.7x10^41 erg/s; 0.5-10 keV) assuming the source belongs to the associated galaxy. We find a candidate optical counterpart in archival HST/ACS g'-band observations of the field containing the galaxy obtained on June 16, 2003. The observed magnitude of g'=26.4±0.1 corresponds to an absolute magnitude of -10.1. We discuss the possible nature of the X-ray source and its associated candidate optical counterpart and conclude that the source is either a very blue type IIn supernova, a ULX with a very bright optical counterpart or a recoiling super-massive black hole.

A super-massive black hole -- heavier than one billion suns -- appears headed on an exit out of its home galaxy at 670,000 miles-an-hour.
Noted by NASA's Chandra X-ray space telescope, the object called CXO J122518.6+144545 resides some 607,000 light years away in the SDSS DR7 galaxy (one light year is about 5.9 trillion miles.) Curiously, the object is about 10,500 light years outside the centre of the galaxy, marked by an accompanying bright spot in the sky, noted by Hubble space telescope images.
