A magnetar giant flare in the nearby starburst galaxy M82
Thuillot, William; Mereghetti, Sandro; Esposito, Paolo +32 more
Magnetar giant flares are rare explosive events releasing up to 1047 erg in gamma rays in less than 1 second from young neutron stars with magnetic fields up to 1015−16 G (refs. 1,2). Only three such flares have been seen from magnetars in our Galaxy3,4 and in the Large Magellanic Cloud5 in ro…
Thermonuclear explosions on neutron stars reveal the speed of their jets
Kuulkers, Erik; Degenaar, Nathalie; Sánchez-Fernández, Celia +6 more
Relativistic jets are observed from accreting and cataclysmic transients throughout the Universe, and have a profound impact on their surroundings1,2. Despite their importance, their launch mechanism is not known. For accreting neutron stars, the speed of their compact jets can reveal whether the jets are powered by magnetic fields anch…
