DES-Fermi Map

Caption

In a new study, astrophysicists have found a certain gamma-ray glow in the sky, known as unresolved gamma-ray background (yellow), to coincide with cosmic regions that contain a lot of matter (red). The correlation could lead to a better understanding of highly energetic astrophysical objects and dark matter. The gamma-ray map was created with nine years of data from the Fermi spacecraft, and the map showing the density of matter is based on one year of data from the Dark Energy Survey (DES).
