The Baryonic and Dark Matter Distributions in Abell 401
We combine spatially resolved ASCA temperature data with ROSAT imaging data to constrain the total mass distribution in the cluster A401, assuming that the cluster is in hydrostatic equilibrium, but without the assumption of gas isothermality. We obtain a total mass within the X-ray core (290 h−1 50 kpc) of 1.2 −0.5×10 h−1 50 M at the 90 % confidence level, 1.3 times larger than the isothermal ...

متن کاملNon-Baryonic Dark Matter
These lectures on non-baryonic dark matter matter are divided into two parts. In the first part, I discuss the need for non-baryonic dark matter in light of recent results in cosmology, and I present some of the most popular candidates for non-baryonic dark matter. These include neutrinos, axions, neutralinos, WIMPZILLAs, etc. In the second part, I overview several observational techniques that...
متن کاملBaryonic Dark Matter in Galaxies
Cosmological nucleosynthesis calculations imply that many of the baryons in the Universe must be dark. We discuss the likelihood that some of these dark baryons may reside in the discs or halos of galaxies. If they were in the form of compact objects, they would then be natural MACHO candidates, in which case they are likely to be the remnants of a first generation of pregalactic or protogalact...
متن کاملNon–baryonic Dark Matter Searches
The emphasise in this review about non–baryonic dark matter will be on experimental approaches to this fast evolving field of astroparticle physics, especially the direct detection method. The current status of experimental techniques will be reviewed and recent highlights as well as future plans will be introduced.
