Is the dark matter halo of the Milky Way flattened ?
We performed an extended analysis of the parameter space for the interaction of the Magellanic System with the Milky Way (MW). The varied parameters cover the phase space parameters, the masses, the structure, and the orientation of both Magellanic Clouds, as well as the flattening of the dark matter halo of the MW. The analysis was done by a specially adopted optimization code searching for th...
متن کاملThe Distribution of Dark Matter in the Milky Way Galaxy
A wealth of recent observational studies shows the dark matter in the Milky Way to have the following fundamental properties: 1) there is no detectable dark matter associated with the Galactic disk – the dark matter is distributed in a purely halo distribution with local volume density near the Earth ≈ 0.3GeV/cc ≡ 0.01M⊙pc; 2) The stellar mass function is both universal and convergent at low ma...

متن کاملThe Milky Way Dark Halo and the Lmc Disk
Stars and their kinematics provide one of the tools available for studies of the shapes of galaxies and their halos. In this review I focus on two specific applications: the shape of the Milky Way dark halo and the shape of the LMC disk. The former is constrained by a variety of observations, but an accurate determination of the axial ratio qDH remains elusive. A very flattened Milky Way dark h...
متن کاملEvidence for dark matter in Milky Way
There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnet...
