Particlebites Reports on Monojet Dark Matter Searches at the LHC
In a special particlebites cross-post, we cover the latest results in the search for a direct detection of dark matter from the LHC.
Looking for Dwarf Galaxies with Cepheids: A Cautionary Tale
Today we use a new paper to revisit the possible dwarf galaxy discovered 90 kpc from the Milky Way.
From Large to Small: Astrophysical Signs of Dark Matter Particle Interactions
The dark matter halos of galaxies and clusters of galaxies—objects of literally astronomical dimensions—have lots to say about the mysterious, likely subatomic, dark matter particle.
Digging into the Core: Dark Matter and Dwarf Galaxies
Dark matter dominated dwarf spheroidal galaxies are some of the best places to test predictions on how dark matter behaves in the Universe. Predictions for how the dark matter should be distributed in these galaxies disagrees with what is actually observed, however. The authors of today’s Astrobite investigate how the dark matter profiles may evolve over time from what is predicted to what we see today.
The Labor of Outflows against Dark Matter Halo
Dark matter permeates the Universe and surrounds every galaxies in the form of dark matter halos. We don’t really know dark matter works, as predictions of standard cosmology, Lambda Cold Dark Matter (ΛCDM), are way off from observations. Is this the death of Cold Dark Matter, or there are something more to it?
Detonating white dwarfs with black holes
Dark matter, in the form of primordial black holes, can potentially trigger Type Ia supernovae in white dwarfs.
