Researchers from The Australian National University (ANU) have found an alternative explanation for a mysterious gamma-ray signal coming from the centre of the galaxy, which was long claimed as a signature of dark matter.
Gamma-rays are the form of electromagnetic radiation with the shortest wavelength and highest energy.
Co-author of the study Associate Professor Roland Crocker said this particular gamma-ray signal — known as the Galactic Centre Excess — may actually come from a specific type of rapidly-rotating neutron star, the super-dense stellar remnants of some stars much more massive than our sun.
The Galactic Centre Excess is an unexpected concentration of gamma-rays emerging from the centre of our galaxy that has long puzzled astronomers.
“Our work does not throw ...
