What did the Fermi telescope discover?
By peering at the cosmos from low Earth orbit, Fermi detected the most powerful gamma-ray blast astronomers have ever seen: a mysterious source glowing with more energy than 9,000 supernovas. Fermi also discovered the first gamma-ray pulsar and gamma-ray “bubbles” around the Milky Way.
What does the Fermi Space telescope study?
The Fermi Gamma-Ray Telescope is a space observatory designed to study the universe in highly energetic frequencies known as gamma-rays. It includes participation from NASA, the U.S. Department of Energy, and several partners both in the United States and internationally.
Why is the Fermi telescope important?
Fermi enables scientists to answer persistent questions across a broad range of topics, including supermassive black-hole systems, pulsars, the origin of cosmic rays, and searches for signals of new physics. When launched on June 11, 2008, Fermi bore the name Gamma-ray Large Area Space Telescope, or GLAST.
What do gamma-ray telescopes observe?
Gamma-ray telescope, instrument designed to detect and resolve gamma rays from sources outside Earth’s atmosphere. Gamma rays are the shortest waves (about 0.1 angstrom or less) and therefore have the highest energy in the electromagnetic spectrum.
What can you do with the Fermi telescope?
In addition to standard analysis using the Fermitools, we will include sessions covering pulsar analysis with the Large Area Telescope and gamma-ray burst analysis with the Gamma-ray Burst Monitor.
How big is the Fermi Gamma ray Space Telescope?
Names Gamma-ray Large Area Space Telescope Mean anomaly 229.00° Mean motion 15.10 rev/day Velocity 7.59 km/s (4.72 mi/s) Epoch 23 February 2016, 04:46:22 UTC
How big is the field of view of Fermi?
The effective area in the center of the field of view is about 7000 cm 2 at 1 GeV, decreasing at lower and higher energy. The Fermi spacecraft orbits the earth in about 96 minutes. It is oriented to point the LAT upward at all time, so the earth does not block the view.
When did the Fermi spacecraft go into orbit?
The Fermi spacecraft was launched into a near-earth orbit on 11 June 2008. The Fermi LAT instrument collaboration is an international effort, funded by agencies in several countries [*]. The LAT is an imaging high-energy gamma-ray telescope covering the energy range from about 20 MeV to more than 300 GeV.
