The Swiss Federal Institute of Technology in Lausanne issued a communique on the 15th that researchers have discovered an atypical photon emission phenomenon from cosmic X-rays, which may be evidence of the existence of dark matter. The study was conducted jointly by the college and the University of Leiden, the Netherlands. Using the European Space Agency's XMM Newtonian Telescope, the researchers analyzed X-rays from the Perseus Cluster and the Andromeda Galaxy and collected thousands of signals. After eliminating known particles and atoms, the researchers found a weak atypical photon emission signal in the X-ray spectrum that could not be attributed to any form of common matter. According to some theories, this signal comes from an extremely rare phenomenon in the universe, a photon emitted by an imaginary dark matter particle "inert neutrino" when it is annihilated. Oleg Ruchaski, a physicist at the Federal Institute of Technology in Lausanne, said: "The distribution of this signal in the galaxy is consistent with the expected dark matter, that is, the signal at the center of the object is strong and concentrated, and the edge is weak and diffuse. He said that in order to verify the results, scientists analyzed the data of the Milky Way and found this phenomenon. The researchers said that if this finding is finally confirmed, it will open a new path for particle physics and astronomy research.
