    NASA’s Fermi Mission Reveals its Highest-energy Gamma-ray Bursts

    Gamma-ray bursts are the most powerful explosions known in the Universe, yet we still don’t understand the physics behind their high-energy radiation. An international team, partly led by OKC researcher Magnus Axelsson, has studied nearly 200 events observed over 10 years, the largest sample collected at these energies thus far. The study reveals many new observational findings, it also tells us that there is still a lot we don’t know.

    GD-1 Stellar Stream and Dark Matter in Our Milky Way

    Streams of stars orbiting in the halo of our Milky Way Galaxy can be used to constrain the shape of our Galaxy's dark matter halo and the amount of mass inside the radius of our Sun's orbit.
