Star formation is one of the fundamental process contributing to galaxy evolution and therefore in shaping the Universe. Yet it is extremely challenging to build a complete view of this process and its interplay with galactic scale properties. The most challenging aspect is to reconcile physical mechanisms, which operate at the smallest spatial scales (i.e. the size of our solar system) all the way up to galactic scale features such as the large star-forming complexes.
Our colleague and friend Per Olof has passed away after a very brief period of illness. Peo, as we all called him, played a key role in the field of neutrino physics, both nationally and in the international arena. He started his career with six years at CERN (1976-1982), and was coordinator and spokesperson for several neutrino experiments using bubble chambers.
A new study is providing evidence for the presence of dark matter in the innermost part of the Milky Way, including in our own cosmic neighbourhood and the Earth’s location. The study demonstrates that large amounts of dark matter exist around us, and also between us and the Galactic centre. The result constitutes a fundamental step forward in the quest for the nature of dark matter.
The Swedish Research Council announced yesterday that a grant application to recruit the 2004 Nobel laureate Frank Wilczek to the Physics Department at Stockholm University was approved. This is extremely exciting news – also for the Oskar Klein Centre.
Dear all, As you have noticed by following the OKC blog, our success is continuing. We had an international mid-term review in the beginning of the year, and we came through with flying colours.
In the beginning of November 2014, The Oskar Klein Centre officially joined the XENON dark matter project. The idea is to detect dark matter particles scattering of heavy nuclei.
Since one of the strongest limitation of dark matter detection is due to cosmic ray induced background, it is important to shield the detectors. For this reason XENON is situated in the Gran Sasso National Laboratory, on the side of a ten kilometer long freeway tunnel crossing the Gran Sasso mountain, about 120 km from Rome. Thus, there is about 1500 meters of rock protecting the laboratory from cosmic ray backgrounds.
