Dark Matter Could Be Present At The Center Of The Milky Way Galaxy

A team of MIT physicists has unearthed an older theory, which claimed that a bright burst of gamma rays released from the center of the Milky Way could be generated by dark matter.

Many physicists have been baffled by a strange energy surplus present in the center of Milky Way. The energy surplus is present in the form of gamma rays, which are known to be the most energetic waves found in the electromagnetic spectrum.

Gamma rays tend to be produced by some of the extreme objects found in the universe, among which we can count supernovae and pulsars.

Previous research has shown that gamma rays are found across the galactic disk, and their sources can be tracked down easily. But the galactic center excess, the glow of gamma rays found in the middle of the Milky Way, features traits that quite fascinating.

The Center Of The Milky Way Galaxy Might Present Dark Matter

Some researchers argued that the gamma rays are generated by a large number of pulsars that spin at an accelerated rate while others believed that a cloud of dark matter is responsible for the phenomenon.

In 2015, a team of researchers from MIT and Princeton University favored the pulsar theory as data collected with the help of a gamma-ray telescope inferred that pulsars were the source.

A different team of MIT researchers claims that the model used by the previous researchers could offer the wrong results. During a test, the team used Fermi data but included a fake dark matter signal that was not detected by the model, which continued to assume that the pulsars remain the are the source.

The new results are quite exciting since they open a gate that was deemed to be closed. It is also argued that the intensity of the fake signal was four times higher than the one emitted by the gamma-ray excess. A paper was published in a scientific journal.
