The First Signal from Dark Matter?

The signal comes from a very rare event in the Universe: a photon emitted due to the destruction of a hypothetical particle, possibly a “sterile neutrino”. If the discovery is confirmed, it will open up new avenues of research in particle physics. “It could usher in a new era in astronomy,” says Oleg Ruchayskiy at Leiden University . “Confirmation of this discovery may lead to construction of new telescopes specially designed for studying the signals from dark matter particles. We will know where to look in order to trace dark structures in space and will be able to reconstruct how the Universe has formed.”

Could there finally be tangible evidence for the existence of dark matter in the Universe? After sifting through reams of X-ray data, scientists in EPFL's Laboratory of Particle Physics and Cosmology (LPPC) and Leiden University believe they could have identified the signal of a particle of dark matter.
