Galactic Center Gamma-Ray Excess | Explained: Dark Matter or Hidden Millisecond Pulsars | Science
The Galactic Center Gamma-Ray Excess is an unexplained bloom of high-energy gamma rays coming from the Milky Way’s core. Scientists debate whether this glow is the smoking gun of dark matter annihilation or the combined light of thousands of faint millisecond pulsars.
In this video we explain the evidence behind the Galactic Center Gamma-Ray Excess, why the idea of dark matter annihilation is so exciting, and how the pulsar hypothesis could also reproduce the observed signal. We walk through what NASA’s Fermi telescope first saw, what upcoming observatories (like the Cherenkov Telescope Array) can test next, and why solving the Galactic Center Gamma-Ray Excess would rewrite our picture of the cosmos.
