Alice Borghese (INAF/Astronomical Observatory of Rome)

Description

Magnetars are the strongest magnets we know of, with magnetic fields reaching values up to 10^15 G at the surface. Transient activity in the X-/gamma ray regime is the birthmark of magnetars. Their radiative variability includes short, explosive events from milliseconds to hundreds of seconds (i.e., bursts and giant flares) and longer-lived outbursts (weeks to months). In this talk, I will review the results obtained from a systematic analysis of outbursts, focusing on a few specific events. Then, I will finish with some considerations on magnetar-like activity from other classes of neutron stars and the possible evolutionary links between different neutron star families.
