What is Fermi?

General Dynamics C4 Systems - Artist Concept of Fermi The Universe is home to numerous exotic and beautiful phenomena, some of which can generate almost inconceivable amounts of energy. Supermassive black holes, merging neutron stars, streams of hot gas moving close to the speed of light ... these are but a few of the marvels that generate gamma-ray radiation, the most energetic form of radiation, billions of times more energetic than the type of light visible to our eyes. What is happening to produce this much energy? What happens to the surrounding environment near these phenomena? How will studying these energetic objects add to our understanding of the very nature of the Universe and how it behaves?

The Fermi Gamma-ray Space Telescope, formerly GLAST, is opening this high-energy world to exploration and helping us answer these questions. With Fermi, astronomers at long last have a superior tool to study how black holes, notorious for pulling matter in, can accelerate jets of gas outward at fantastic speeds. Physicists are able to study subatomic particles at energies far greater than those seen in ground-based particle accelerators. And cosmologists are gaining valuable information about the birth and early evolution of the Universe.

For this unique endeavor, one that brings together the astrophysics and particle physics communities, NASA has teamed up with the U.S. Department of Energy and institutions in France, Germany, Japan, Italy and Sweden. General Dynamics was chosen to build the spacecraft. Fermi was launched June 11, 2008 at 12:05 pm EDT.

LAT Light Curve Repository

The Fermi Large Area Telescope Collaboration has released a repository of flux light curves for more than 1500 variable sources from the LAT catalog calculated on 3-day, 1-week, and 1-month time intervals. The light curves will be frequently updated as new data arrives. The web interface to the repository provides a visualization capability with catalog overlays as well as a search feature. You can find a additional details here.

Dr. Ke Fang Receives the 2021 Shakti P. Duggal Award

Congratulations to Dr. Ke Fang, professor at the University of Wisconsin-Madison, on the 2021 Shakti P. Duggal Award presented by the International Union of Pure and Applied Physics (IUPAP). Fang's research focuses on understanding the universe through its energetic messengers, including ultra-high-energy cosmic rays, gamma rays, and high-energy neutrinos, with HAWC, Fermi, and IceCube.
