• Prof explores universe through gravity lens studies

    Updated: 2012-04-30 09:20:06
    (Phys.org) -- The National Science Foundation recently awarded Dr. Mustapha Ishak-Boushaki, associate professor of physics at UT Dallas, a $222,000 research grant for his investigations of the gravitational lensing technique used to study the nature of the universe.

  • X-ray quasars, and a distance record

    Updated: 2012-04-30 08:59:00
    Quasars are thought to be galaxies whose bright nuclei contain massive black holes around which disks are actively accreting matter. The accretion process releases vast amounts of energy, often including a wind, and as a result quasars are among the most powerful energy sources known. Because they are so bright, quasars can be seen even when they are very far away, and this combination of being both highly energetic and located at cosmological distances makes them appealing to astronomers trying to figure out the nature of galactic center black holes (our own Milky Way has one) and the conditions in the early universe that prompt these monsters to form.
