Galaxy collisions not the only source of monster black hole activity | Space | EarthSky - 1 views

    In a surprise announcement earlier today (July 13), the European Southern Observatory said that monster black holes - those giants of millions or billions of solar masses, thought to lurk at the hearts of most galaxies - have a mechanism to become active other than galaxy collisions.
  • LeopoldS on 16 Jul 11
     
    "A new study combining data from ESO's Very Large Telescope and ESA's XMM-Newton X-ray space observatory has turned up a surprise. Most of the huge black holes in the centers of galaxies in the past 11 billion years were not turned on by mergers between galaxies, as had been previously thought." and "The process that activates a sleeping black hole - turning its galaxy from quiet to active - has been a mystery in astronomy. What triggers the violent outbursts at a galaxy's center, which then becomes an active galactic nucleus? Up to now, many astronomers thought that most of these active nuclei were turned on when two galaxies merged, or when they passed close to each other and the disrupted material became fuel for the central black hole. Results of the new study indicate this idea may be wrong for many active galaxies." very interesting indeed

  • “That’s impossible!” he told Borne. “Don’t you realize that the entire data set NASA has collected over the past 45 years is one terabyte?”
  • The LSST, producing 30 terabytes of data nightly, will become the centerpiece of what some experts have dubbed the age of peta­scale astronomy—that’s 1015 bits (what Borne jokingly calls “a tonabytes”).
  • A major sky survey might detect millions or even billions of objects, and for each object we might measure thousands of attributes in a thousand dimensions. You can get a data-mining package off the shelf, but if you want to deal with a billion data vectors in a thousand dimensions, you’re out of luck even if you own the world’s biggest supercomputer. The challenge is to develop a new scientific methodology for the 21st century.”

    And here's the arXiv paper http://arxiv.org/abs/1109.4897 Serious? Difficult to say. I'm theorist and can't really rate their measurement techniques. Certainly be cautious, mostly such things disappear faster than they appeared.
  • LeopoldS on 23 Sep 11
     
    it took them 3 years to "appear"!
  • Luzi Bergamin on 23 Sep 11
     
    Leo, you mean that they measured 3 years? That's not a point to criticize: since the only interaction of neutrinos with matter is the Weak Interaction (which is indeed very, very weak), it is extremely hard to get a reasonable statistic. By the same reason, it's essentially impossible to shield the experiment from the background. And this background (solar neutrinos, cosmic radiation neutrinos) is huge.
  • pacome delva on 28 Sep 11
     
    for sure a result to be taken seriously. It makes a buzz in my lab... but always be cautious with this kind of declaration, that hugely violates all physics we know and even most of the reasonable alternative theories... Remember the Pionneer anomaly for which it took almost ten years to set up that finally its a thermal effect.

    Physicists working on the LHCb experiment at the CERN particle-physics lab have released the best evidence yet for direct charge-parity (CP) violation in charm mesons....While more data must be analysed to confirm the result, the work could point to new physics beyond the Standard Model and help physicists understand why there is more matter than antimatter in the universe.
