Dark Matter in the Centre of our Home Galaxy
Fermi telescope made clean observation of excess γ-ray emission at the centre of our home galaxy which appeared non-spherical and flattened............

On this day five years ago, an international team led by researchers at @mpi_grav in Hannover, Germany, identified a Galactic “mystery source” of gamma rays.
It contains a heavy neutron star with a very low mass companion orbiting it. Using novel data analysis methods running on about 10,000 graphics cards in the distributed computing project @einsteinathome, the team identified the neutron star by its regularly pulsating gamma rays in a deep search of data from NASA's Fermi satellite.

Heute vor fünf Jahren löste ein internationales Team unter Leitung von Forschenden des @mpi_grav in Hannover das Rätsel um eine galaktische Gammastrahlenquelle.
In ihr steckt ein schwerer Neutronenstern, den ein sehr leichter Begleiter umrundet. Mittels neuartiger Datenanalysemethoden, die auf rund 10.000 Grafikkarten im verteilten Rechenprojekt @einsteinathome liefen, wies das Team den Neutronenstern anhand seines regelmäßigen Gammastrahlenblinkens durch eine aufwändige Suche in Daten des Fermi-Satelliten der NASA eindeutig nach.

🎉 A new paper with Einstein@Home gamma-ray pulsar discoveries 🔭
The new publication “Einstein@Home Searches for Gamma-ray Pulsars in the Inner Galaxy” was accepted for publication in The Astrophysical Journal and is posted on the arXiv preprint server today.
📄 https://arxiv.org/abs/2509.21307
The international science team reports the discovery of four previously unknown gamma-ray pulsars towards the direction of the Galactic Center. Most likely the four discoveries are foreground sources from the Galactic disk.
