On 20–12 September, CERN hosted the fifth annual Mediterranean-Antarctic Neutrino Telescope Symposium (MANTS). For the first time, the meeting was organized under the GNN umbrella.
Read article 'Ultra-luminous X-ray source is ‘just’ a pulsar'
Until now, ultra-luminous X-ray sources (ULXs) were thought to be black holes, because their high luminosity implied a mass exceeding by far the maximal mass of a neutron star. The most luminous of th...
