 | Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. This the latest of several successful MOND predictions raises new questions about accuracy of the reigning cosmological model of the universe, writes McGaugh in a paper to be published in March in Physical Review Letters.MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. ...> Full Article |
 | An international team led by a cosmologist at Lawrence Berkeley National Laboratory has extended the relationship between the x-ray luminosity and the mass of galaxy clusters as measured by gravitational lensing, improving the reliability of mass measurements of much older, more distant, and smaller galactic structures. These refined measurements will benefit both the understanding of dark matter and the nature of dark energy as well. ...> Full Article |
 | During its first year of operations, NASA's Fermi Gamma
Ray Space Telescope mapped the extreme sky with unprecedented
resolution and sensitivity. It captured more than one thousand
discrete sources of gamma rays -- the highest-energy form of light.
Capping these achievements was a measurement that provided rare
experimental evidence about the very structure of space and time,
unified as space-time in Einstein's theories. ...> Full Article |
