Today we feature a recent article from our sister site particlebites exploring new theory on dark matter interactions,
For a few years now, excess emission of gamma-rays in the direction of the Galactic Center has puzzled scientists. In the paper we discuss today, the authors re-analyze data from the Fermi telescope to get new insights into the origin of this excess emission. They make the case for the signal being described by dark matter particles annihilating in the center of our Galaxy.
In today’s astrobite, we discuss the puzzling results from the AMS-02 experiment, which has detected an excess of positrons in cosmic rays with respect to what we expect from known physical sources. Where are those positrons coming from?
The Cryogenic Dark Matter Search experiment has found signatures in its data consistent with a dark matter Weakly Interacting Massive Particle. While not confident enough to declare a dark matter discovery, they estimate that there is only a 0.2% chance that these signatures are caused by random chance.
The quest for identifying the dark matter particle is well underway. Today, we discuss the work of the ANTARES collaboration, which is using a neutrino telescope to search for signals of dark matter annihilation in the Sun.
If WIMPs are the solution to the dark matter problem, it’s reasonable to ask what sort of impact they would have on human beings. This paper answers that question.
