"When we look at well-known astrophysical events, like star explosions, they haven't been able to provide a full explanation for mysteries like the specific energy and shape we've observed coming from the centre of the Milky Way. Now, we've shown how one excited dark matter model could account for at least two - possibly even three - of these kind of unexplained signals at once."
"Dark matter is an elusive substance which makes up roughly a quarter of the universe, but cannot be observed through any normal means. Since dark matter doesn't interact with normal matter, even our most powerful telescopes cannot see it directly. However, scientists believe that this strange substance may be indirectly producing the baffling behaviour of our galaxy's turbulent core."
"The heart of the Milky Way is an exceptionally chaotic and violent place, where immense forces pull and crush clouds of dense gases into fast-moving stars. At the very core is the supermassive black hole Sagittarius A*, which has a mass around four million times greater than that of the sun."
Astronomers have long puzzled over strange energy spikes originating from the Milky Way's center. Researchers now propose that excited dark matter, a specific type of dark matter, generates these mysterious signals. Dark matter comprises roughly a quarter of the universe but remains invisible to telescopes since it doesn't interact with normal matter. The galactic core, dominated by the supermassive black hole Sagittarius A*, is an extremely violent environment where intense gravity and heat produce radiation. Scientists observed unexplained phenomena, including a sharp spike in gamma-ray radiation at the 511-keV emission line. Traditional astrophysical events like star explosions fail to explain these observations. A new model demonstrates that excited dark matter could account for at least two, possibly three, of these unexplained signals simultaneously.
