Dark Matter Annihilation is for WIMPs
Today’s paper searches for signatures of annihilating dark matter in the Milky Way’s satellite dwarf galaxies.
Red Giants Have it All: Dark Matter Constraints from Stellar Evolution
How can astronomers use existing understandings of stellar evolution to better study dark matter?
Do the Milky Way’s Stellar Streams have that Fuzzy (Dark Matter) Feeling?
Stellar streams are an excellent tool for probing the nature of Dark Matter. Today’s paper tests whether Fuzzy Dark Matter is a viable theory by evaluating the thinness of streams in the Milky Way.
Particlebites reports on elastically decoupling dark matter
Today we feature a recent article from our sister site particlebites exploring new theory on dark matter interactions,
Gamma-rays from the Galactic Center, a dark matter
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.
Where are the positrons coming from?
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?
