Robert Archibald published the first firm detection of an anti-glitch in a magnetar. An anti-glitch is a sudden decrease of the rotation period of a magnetar (a neutron star with a very large magnetic field), by opposition to the frequently-observed glitches which are sudden increase of the period (spin-up). This discevery can have important implications for the understanding of the internal structure of these extreme objects .
