A magnetar is a type of neutron star with an extremely powerful magnetic field. The magnetic field decay powers the emission of high-energy electromagnetic radiation, particularly X-rays and gamma rays. The magnetar hypothesis has become widely accepted as a likely explanation for soft gamma repeaters(SGRs) and anomalous X-ray pulsars (AXPs).
A series of lectures on fundamental problems of Particle and Astroparticle Physics. Lectures will cover a wide spectrum of hot problems starting from the precision physics in the Standard Model and new physics beyond the Standard Model, Gravity, Cosmology and High Energy Cosmic Messengers
