Antiproton signatures from astrophysical and dark matter sources at the galactic center

Understand

The center of our Galaxy is a complex region characterized by extreme phenomena.

• The presence of the supermassive Sagittarius A* black hole, a high Dark Matter density and an even higher baryonic density are able to produce very energetic processes.
• Indeed, high energetic gamma rays have been observed by different telescopes, although its origin is not clear.
• In this work, we constrain the possible antiproton flux component associated to this signal.
