Detonating white dwarfs with black holes
Dark matter, in the form of primordial black holes, can potentially trigger Type Ia supernovae in white dwarfs.
Hot Shots: How to Trigger Star Formation in the Early Universe by Supernova Blast-Waves
Stars formed in the early Universe were extremely massive and extremely low in elements heavier than helium. The transition from the first to the second generation of stars is still hidden in the shadows of the past. However, simulations of the most massive supernovae can help us to decipher the way of how the life cycle of stars came into being.
A Possible Detection of Dark Matter in a Dwarf Galaxy!
If dark matter particles can collide to release gamma-rays, the best place to see them will be in the centers of dwarf galaxies. Archival Fermi-LAT images around Reticulum 2 show the first ever detection of gamma-rays from a dwarf galaxy. Dark matter detection may be close at hand!
Just How Dark is Dark Matter?
How do you get a glimpse of dark matter? Stare really hard at the outskirts of galaxies and hope the matter isn’t totally dark.

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.
