Bubbles in pulsar wind strike sparks


MPIK Physicists have found a new theoretical model for the mysterious variable emission of high-energy gamma rays from the Crab Nebula. Since their discovery by the AGILE and Fermi experiments in 2009 these flares had been unexplained so far. A sudden drop in the mass loading of the pulsar wind of the Nebula results in an inductive acceleration of only few charged particles while the energy carried per particle is strongly enhanced. On impacting the Nebula, these particles produce bursts of hard gamma-rays, similar to those observed. [Physical Review Letters, Nov 21, 2017]

Two suspected stars not responsible for mysterious antiparticle excess


A mountaintop observatory in Mexico, built and operated by an international team of scientists, has captured the first wide-angle view of very-high-energy light emanating from two rapidly spinning stars, so-called pulsars. The fresh perspective on these stellar neighbors – which are both close to us in cosmic terms – casts serious doubt on one possible origin for a mysterious excess of particles near Earth that has tantalized scientists in recent years.
