Many of them have one thing in common:
Fermi is picking up crazy charged particles via electromagnetic
waves - and it’s detecting so many of them Fermi has been able to
produce the first all-sky map of the very high energy universe.
Its main instrument is the Large Area Telescope (LAT), with
which astronomers mostly intend to perform an all-sky survey
studying astrophysical and cosmological phenomena such as active
galactic nuclei, pulsars, other high-energy sources and dark matter.
Dave Thompson, an astrophysicist at NASA’s Goddard Space Flight Center gave us his answer.
Strange radiation streaming from the core of our Milky Way galaxy may be a long-sought signal of dark matter, the elusive stuff thought to make up much of the universe.
The charged particles cannot be explained by the structural mechanisms in the galaxy, and it cannot be charged particles from supernova explosions.
It is believed this could be
proof of dark
matter - otherwise, we have discovered an absolutely new (and
unknown) mechanism of acceleration of particles in the galactic
The estimated mass of the halo is comparable to
the mass of
all the stars in the galaxy.
These jets can influence many galactic processes, of which is still to be determined.
