There is an interesting paper in Physical Review Letters this week with the mouthful of a title: “Enhancement of electron energy to the multi-GeV regime by a dual-stage laser-wakefield accelerator ...

Gamma-ray bursts (GRBs) are the most electromagnetically luminous cosmic explosions. They are powered by collimated streams of plasma (jets) ejected by a newborn stellar-mass black hole or neutron ...

New experiments at CERN by an international team have ruled out a potential source of intergalactic magnetic fields. The existence of such fields is invoked to explain why we do not observe secondary ...
