About AMEGO-X

AMEGO-X, the All-sky Medium-Energy Gamma-ray Observatory eXplorer, is a multimessenger astronomy mission concept proposed to the 2021 MIDEX Announcement of Opportunity, to be launched no later than Dec. 2028.

Multimessenger astrophysics (New Messengers New Physics) is a priority theme of the Astro2020 Decadal Survey report, and the highest priority for space missions on small and medium scale platforms. This science is poised to revolutionize our understanding of the extreme universe. Data from AMEGO-X will answer the following questions pertaining to all cosmic messengers:

• Do supermassive black holes accelerate cosmic rays and produce neutrinos?
• How do binary neutron star mergers produce relativistic jets and what is the structure of those jets?
• Where are the cosmic rays accelerated in our Galaxy?

To answer these questions, AMEGO-X will be sensitive to gamma-ray photons in the energy range from about 100 keV to 1 GeV and transient events down to about 25 keV. During its three-year baseline mission, AMEGO-X will observe nearly the entire sky every two orbits, building up a sensitive all-sky map of gamma-ray sources and emission. Want to learn more?
