Scientists may soon confirm dark matter’s existence by studying a diffuse glow of gamma rays near the center of our galaxy. A recent study suggests that dark matter particles could be responsible for these gamma-ray emissions, which are also possible explanations for a phenomenon observed in another region.
To test this hypothesis, researchers used advanced simulations to weigh the merits of two competing theories: dark matter particle collisions and millisecond pulsars. The results indicate that both scenarios produce similar gamma-ray signals, making it challenging to distinguish between them. However, the Cherenkov Telescope Array Observatory, scheduled for completion by 2026, may be able to provide definitive answers.
The excess in gamma rays was observed near the innermost 7,000 light-years of the galaxy and is thought to be evidence of dark matter annihilation. Dark matter particles are believed to annihilate completely when they collide, generating gamma rays as a byproduct. This phenomenon is unique to simple dark matter theories, which propose that dark matter particles are their own antiparticles.
While the study’s findings are promising, it’s essential to note that no direct detection of dark matter particles has been made yet. The Cherenkov Telescope Array Observatory will provide an opportunity to differentiate between the gamma-ray emissions from these two sources and shed light on one of the universe’s greatest mysteries.
