On this day seven years ago, an international research team (led by @mpi_grav and @MPIfR_Bonn) published the first millisecond pulsar flashing only in gamma rays.
The discovery was possible thanks to the volunteer distributed computing project @einsteinathome, which the researchers used to find many more gamma-ray pulsars.
Millisecond pulsars are neutron stars – remnants of stellar explosions about 20 km in size with strong magnetic fields – that spin many hundreds of times per second around their axis.
Prior to this discovery, all millisecond pulsars observed in gamma rays also emitted radio waves. The newly discovered “PSR J1744-7619” (rotating 213 times per second) is the first known exception.
