An international team of researchers has discovered the Milky Way’s smallest satellite galaxy associated with dark matter, the emission of which is said to be the result of millisecond pulsars breaking away from cosmic particles.
The center of the main galaxy is blowing a huge bubble of gamma rays that span 50,000 light-years.
Gamma rays discovered by the Fermi Gamma-Ray Space Telescope almost a decade ago have left the source of this hourglass-shaped fact unknown.
It is known as the Fermi bubble, a pair of radiation that repairs into a slightly mysterious substructure of very bright gamma-ray emission. The Fermi cocoon, called the brightest spot, was discovered in the southern lobe, and is thought to have arisen from the eruption of a galaxy’s supermassive black hole in the past.
An international group of researchers, jointly led by Oscar Macias, former project researcher at the Kavli Institute for Space Physics and Mathematics, and Associate Professor Roland Crocker at the Australian National University, evaluated information from the Fermi Space Telescope and GAAIA to reveal that the Fermi Cocoon is in action. Emission of the Sagittarius Dwarf Galaxy.
Researchers have shown that gamma-ray cocoons can be produced by millisecond pulsars in the Sagittarius dwarf, and oppose the sophistication of dark matter.
This is essential because dark matter researchers hoped that gamma irradiation from dwarf satellites would signal a smoking gun for dark matter destruction.
