Pulsare gelten als Leuchttürme im All. Diese kompakten und schnell rotierenden Neutronensterne blinken im Radio- oder Gammawellenbereich mehrmals pro Sekunde auf. Reine Gammapulsare sind extrem schwer zu finden, da sie trotz der hohen Energie nur sehr wenige Photonen pro Zeiteinheit abstrahlen. Mit einem verbesserten Analysealgorithmus haben nun Max-Planck-Wissenschaftler in internationaler Kooperation eine Reihe bisher unbekannter und besonders leuchtschwacher Gammapulsare in den Daten des Satellitenobservatoriums Fermi aufgespürt. Damit hat sich deren Anzahl auf mehr als 100 erhöht.
Die kosmischen Leuchtfeuer stellen die Astronomen noch vor manches Rätsel.
