Their 90% confidence upper limit of 1.1 eV halves the previous best model-independent bound with just one month of data.
The $3 million prize will be shared equally between 347 researchers who were co-authors of the six papers published by the EHT collaboration on 10 April.
The inferred mass, spin and age of M87* are incompatible with the existence of fuzzy dark matter with masses of the order of a few 10-21 eV.
A public colloquium and press conference will be webcast on Monday.
On 10 July, CERN and the Astroparticle Physics European Consortium (APPEC) founded a new research centre for astroparticle physics theory called EuCAPT.
CERN has signed a collaboration agreement with the European Space Agency to address the challenges of harsh radiation environments.
For many years the search for its extremely rare decay to a μ+μ– pair was a holy grail of particle physics.
Achieving 8% precision on the Higgs cross section is a significant step towards studying the electroweak symmetry breaking mechanism.
The LHCb collaboration recently reported the results of searches for two complementary charged-lepton-flavour violating decays.
