Dark Matter distribution in the Milky Way: microlensing and dynamical constraints
Dark Matter distribution Milky Way microlensing dynamical constraints
2011/10/20
We show that current microlensing and dynamical observations of the Galaxy allow to set interesting constraints on the Dark Matter local density and profile slope towards the galactic centre. Assuming...
The outer haloes of the Milky Way and Andromeda galaxies contain as much important information on their assembly and formation history as the properties of the discs resident in their centres. In this...

Energetic radiation pulsing from the belly of the Milky Way is the clearest signal yet of dark matter. That is according to a pair of astrophysicists in the US who reach this conclusion after scrutini...
Dark Matter in late-type galaxies。
Using X-ray observation we have obtained the deprojected gas density and temperature profiles for a sample of cluster of galaxies. We show that cool-core clusters, which are expected to be the largest...
