Dark Matter Not Ruled Out as Source of Milky Way Gamma Ray Glow, Study Shows
An international research collaboration involving the University of Vienna and Lawrence Berkeley National Laboratory in the United States has re-examined the mysterious Galactic Center Excess (GCE). Utilizing machine learning, their study revisited the faint, spherical glow of gamma rays observed at the Milky Way's core, which has puzzled physicists for over a decade. The new findings suggest that dark matter cannot currently be dismissed as an explanation for this astronomical phenomenon.
An international research collaboration, formed by the University of Vienna and Lawrence Berkeley National Laboratory in the United States, has employed machine learning to reassess one of astrophysics' most debated signals.
The signal in question is known as the Galactic Center Excess (GCE), characterized as a faint, roughly spherical emission of gamma rays located at the center of the Milky Way galaxy. This perplexing phenomenon has captured the attention of physicists for more than ten years.
The recent analysis indicates that an explanation involving dark matter cannot presently be excluded as the cause of the GCE. This finding challenges previous assumptions and reopens possibilities for understanding the signal's origin.
The results of this collaborative research have been published in the journal Physical Review Letters.
