Dustin Swarm is a high-energy astrophysicist who studies the extreme conditions of the universe: hot gas, massive stars, explosive events, and extreme gravitational and magnetic fields. He also works in technology development for X-ray and gamma ray telescopes. Swarm is designing telescope mirrors that will focus light from positron annihilation in our galaxy. Because these events are incredibly energetic, conventional telescopes are unable to focus the light they produce.
