In a new study by the IceCube, Pierre Auger, and Telescope Array Collaborations, VUB scientists have looked for correlations between the highest energy neutrino candidates in IceCube and the highest energy CRs in these two cosmic-ray observatories. The results, submitted today to the Journal of Cosmology and Astroparticle Physics, have not found any correlation at discovery level. However, potentially interesting results have been found and will continue to be studied in future joint analyses.
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.
