Caught in the act: Herschel detects gigantic storms sweeping entire galaxies clean

May 09, 2011
With observations from the PACS instrument on board the ESA Herschel space observatory, an international team of scientists led by the Max Planck Institute for Extraterrestrial Physics have found gigantic storms of molecular gas gusting in the centres of many galaxies. Some of these massive outflows reach velocities of more than 1000 kilometres per second, i.e. thousands of times faster than in terrestrial hurricanes. The observations show that the more active galaxies contain stronger winds, which can blow away the entire gas reservoir in a galaxy, thereby inhibiting both further star formation and the growth of the central black hole. This finding is the first conclusive evidence for the importance of galactic winds in the evolution of galaxies. [more]

No direct link between black holes and Dark Matter

January 20, 2011
Massive black holes have been found at the centres of almost all galaxies, where the largest galaxies - who are also the ones embedded in the largest halos of Dark Matter - harbour the most massive black holes. This led to the speculation that there is a direct link between Dark Matter and black holes, i.e. that exotic physics controls the growth of a black hole. Scientists at the Max Planck Institute of Extraterrestrial Physics, the University Observatory Munich and the University of Texas in Austin have now conducted an extensive study of galaxies to prove that black hole mass is not directly related to the mass of the Dark Matter halo but rather seems to be determined by the formation of the galaxy bulge. Their findings are published in a Letter to the journal Nature on 20th January. [more]

Space telescope catches antimatter from terrestrial thunderstorms

January 10, 2011
Normally astronomers look deep into space, but in the latest finding from the NASA Fermi Gamma-ray Space Telescope presented on Monday, Jan. 10, during a news briefing at the American Astronomical Society meeting, they detected an antimatter signal from Earth. Created in energetic processes above thunderstorms, when such an antimatter beam strikes the spacecraft, it actually becomes a source of the gamma-ray light it was designed to observe. Scientists at the Max Planck Institute for Extraterrestrial Physics (MPE) were responsible for the development of the detectors and the power supplies of the Fermi Gamma-ray Burst Monitor (GBM), which led to this discovery, and contributed to the calibration and data analysis for this particular result.
