A team of astronomers using ESO’s Very Large Telescope (VLT) has captured the most detailed images ever of the hypergiant star VY Canis Majoris. These observations show how the unexpectedly large size of the particles of dust surrounding the star enable it to lose an enormous amount of mass as it begins to die. This process, understood now for the first time, is necessary to prepare such gigantic stars to meet explosive demises as supernovae. Prof. Joris Blommaert (Astronomy and Astrophysics Research Group, VUB) is co-author of the paper presenting the results of the observations.
The Astronomy and Astrophysics Research Group of the Vrije Universiteit Brussel (VUB) in Belgium is hiring 2 PhD researchers and 1 postdoctoral researcher in radio detection of cosmic particles with the LOFAR radio telescope. The research program is funded by the European Research Council (ERC).
Together with the universities from Wisconsin and Delaware and the Observatoire de Paris, Gwenhaël de Wasseige and the team of the Vrije Universiteit Brussel have developed a totally new way to search for these interesting neutrinos by using satellite data.
Today, CERN's Large Hadron Collider (LHC) started delivering physics data for the first time in 27 months. After an almost two year shutdown and several months re-commissioning, the LHC is now providing collisions to all of its experiments at the unprecedented energy of 13 TeV, almost double the collision energy of its first run. This marks the start of season 2 at the LHC, opening the way to new discoveries. The LHC will now run round the clock for the next three years.
Lieve Lambrechts, doctoral researcher at the Applied Physics Research Group, received the best oral presentation award at the 18th Annual Workshop of the IEEE Photonics Benelux Chapter on Friday May 22nd in Mons. The goal of this workshop is to provide a platform for young researchers in the field of photonics to interact, share information and discuss their latest results.
Geneva, 13 May 2015. In an article published today in Nature, the CMS and LHCb collaborations, including physicists from the VUB particle physics department, describe the first observation of the very rare decay of the B0s particle into two muon particles. The Standard Model, the theory that best describes the world of particles, predicts that this rare subatomic process happens about four times out of a billion decays, but it has never been seen before. These decays are studied as they could open a window to theories beyond the Standard Model, such as supersymmetry. The analysis is based on data taken at the Large Hadron Collider (LHC) in 2011 and 2012. These data also contain early hints of a similar, but even more rare decay into two muons of the B0, a cousin of the B0s.
