Back in 2009, scientists first discovered that our galaxy has got a source of extra gamma rays right in its center. However, at the time, there was no explanation of the excess gamma rays. And now, scientists finally think that they have finally understood the source of the excess gamma rays.
Since the discovery, the group of scientists has been using Fermi Large Area Telescope to observe the gamma rays. After creating a model, scientists have come up with the idea that Pulsars, incredibly dense, rapidly-spinning cores of ancient stars might be causing the phenomenon.
In order to explain the source, the researchers had made list of possible objects that could be contributing towards the excess gamma rays and cut the list down to 66 possible sources. Afterwards, they put the updated data back to the simulation and the simulation seemingly confirmed pulsars as the source of the excess radiation.
Prior to this, researchers testes dark matter particle as they were also thought to be the source of radiation as dark matter account for nearly 80 percent of the gravitational force. While the new research seemingly disproved the theory, we’ll need to wait and see to find out more about the results. This is largely due to the fact that the paper was posted on arXiv as a preprint and will need to get input from other researchers before the source can be confirmed. Whatever the cause is, it’s true that we might get definite result in the coming months.
