  • The curious case of the warped Kuiper Belt
    on June 22, 2017 at 2:40 pm

  • Radioactive elements in Cassiopeia A suggest a neutrino-driven explosion
    on June 22, 2017 at 12:27 pm

    Stars exploding as supernovae are the main sources of heavy chemical elements in the Universe. In particular, radioactive atomic nuclei are synthesized in the hot, innermost regions during the explosion and can thus serve as probes of the unobservable physical processes that initiate the blast. Using elaborate computer simulations, a team of researchers was able to explain the recently measured spatial distributions of radioactive titanium and nickel in Cassiopeia A, a roughly 340 year old gas remnant of a nearby supernova. […]

  • New strategy to search for ancient black holes
    on June 13, 2017 at 2:29 pm

    An interdisciplinary team of physicists and astronomers has devised a new strategy to search for 'primordial' black holes produced in the early universe. Such black holes are possibly responsible for the gravitational wave events observed by the Laser Interferometer Gravitational-Wave Observatory. […]

  • The largest virtual Universe ever simulated
    on June 9, 2017 at 2:22 pm

    Researchers have simulated the formation of our entire Universe with a large supercomputer. A gigantic catalogue of about 25 billion virtual galaxies has been generated from 2 trillion digital particles. This catalogue is being used to calibrate the experiments on board the Euclid satellite, that will be launched in 2020 with the objective of investigating the nature of dark matter and dark energy.

  • Cosmic inflation: Higgs says goodbye to his 'little brother'
    on June 8, 2017 at 4:36 pm

    In the first moments after the Big Bang, the Universe was able to expand even billions of billions of billions of times faster than today. Such rapid expansion should be due to a primordial force field, acting with a new particle: inflaton. From the latest analysis of the decay of mesons, carried out in the LHCb experiment by physicists from Cracow and Zurich, it appears, however, that the most probable light inflaton almost certainly does not exist. […]

  • Celestial boondocks: Study supports the idea we live in a void
    on June 7, 2017 at 6:29 pm

    A new study not only firms up the idea that we exist in one of the holes of the Swiss cheese structure of the cosmos, but helps ease the apparent disagreement between different measurements of the Hubble Constant, the unit cosmologists use to describe the rate at which the universe is expanding today. […]

  • Knowledge by simplification: Scientists explore strong force
    on June 2, 2017 at 12:50 pm

  • Muon magnet's moment has arrived
    on June 1, 2017 at 5:56 pm

    On May 31, the 50-foot-wide superconducting electromagnet at the center of the Muon g-2 experiment at Fermilab saw its first beam of muon particles from Fermilab's accelerators, kicking off a three-year effort to measure just what happens to those particles when placed in a stunningly precise magnetic field. The answer could rewrite scientists' picture of the universe and how it works. […]

  • Do stars fall quietly into black holes, or crash into something utterly unknown?
    on May 30, 2017 at 3:51 pm

    Astronomers have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful test for Albert Einstein's General Theory of Relativity. […]

  • Supermassive black holes found in two tiny galaxies
    on April 17, 2017 at 6:49 pm

    Astronomers have found two ultra-compact dwarf galaxies with supermassive black holes, the second and third such galaxies found to harbor the objects. Together, the three examples suggest that black holes lurk at the center of most ultra-compact dwarfs, potentially doubling the number of supermassive black holes known in the universe. The tiny galaxies were likely leftovers of larger galaxies stripped of their outer layers after colliding into other, larger galaxies. […]
