Abstract
LMC pulsar's bright gamma-ray flashes
Pulsars are rapidly rotating neutron stars that are seen as pulsating sources of radio waves. Some, such as the Crab pulsar, also emit pulses of gamma rays. The Fermi LAT collaboration observed pulsed gamma rays from a pulsar outside our galaxy, the Milky Way. The pulsar, known as PSR J0540–6919, is located in the Large Magellanic Cloud (LMC). This is the most powerful gamma-ray pulsar yet known, with luminosity 20 times that of the Crab. The findings should help to explain how pulsars convert the energy stored in their rotation into detectable electromagnetic emission.
