For millennia, humans have been fascinated by the mysteries of the cosmos. From ancient civilizations such as the Babylonians, Greeks, and Egyptians to modern-day astronomers, the allure of the starry...
The dark matter assembly of the Local Group in constrained cosmological simulations of a LambdaCDM universe
galaxies:haloes cosmology:theory methods
2011/8/24
We make detailed theoretical predictions for the assembly properties of the Local Group (LG) in the standard LambdaCDM cosmological model. We use three cosmological N-body dark matter simulations from...
Dark Matter as a Relativistic Inertial Effect in Einstein Canonical Gravity?
Dark Matter Relativistic Inertial Effect Einstein Canonical Gravity
2010/11/16
After the study of non-inertial frames in special relativity with emphasis on the problem of clock synchronization (i.e. of how to define 3-space), an overview is given of Einstein canonical gravity i...
No evidence for a dark matter disk within 4 kpc from the Galactic plane
rk matter disk Galactic plane
2010/11/11
We estimated the dynamical surface mass density () at the solar Galactocentric distance between 2 and 4 kpc from the Galactic plane, as inferred from the observed kinematics of the thick disk. We fin...
