We introduce Super-Resonant Dark Matter a model of self-interacting dark matter based on the low energy effective theory of supersymmetric QCD.

. The cuspcore problem is one of the main challenges of the cold dark matter paradigm on small scales. According to this theory the Milky Way is made up of sheets of cold collisionless dark matter particles with angular momentum that flow in and out. Vertical axis is speed of rotation about the galactic center. It is a hypothetical region that has decoupled from cosmic expansion.

The density of a dark matter halo is predicted to rise rapidly toward. Our models include an axisymmetric NFW dark matter halo whose mass and density axis ratio have been determined by fitting the kinematics of 143 GCs 91 with accurate. A dark matter halo is the halo of invisible matter that permeates and surrounds a galaxy or a cluster of galaxies. A MACHO is a body that emits little or no.

Dark matter halos play a key role in current models of galaxy formation and evolution. According to modern models of physical cosmology a dark matter halo is a basic unit of cosmological structure. A massive seed black hole that the collapse of a dark matter halo.

Simulations of the formation of dark-matter halos show that violent relaxation occurs but is never complete in the sense that the final energy of particles are correlated with their initial energy. A dark matter halo is a hypothetical component of a galaxy which extends beyond the edge of the visible galaxy and dominates the total mass. The visible part of most galaxies is embedded in a dark matter DM halo of yet unknown composition observable only through its gravitational interaction with the baryonic matter. Halos and dark matter.

A massive astrophysical compact halo object is a kind of astronomical body that might explain the apparent presence of dark matter in galaxy halos. At the locations of closest. Although dark matter has never been detected in laboratories. A recipe for discovery Shot in the dark.

This halo is invisible but its mass exerts a. What is a dark matter halo. Dark Matter Halo Mass Profiles Dan Coe I provide notes on the NFW Einasto Sersic and other mass profiles which provide good fits to simulated dark matter halos S3. According to the standard model of cosmology the vast majority of galaxies are surrounded by a halo of dark matter particles.
