Fitting galactic rotation curves with conformal gravity and a global quadratic potential
galactic rotation curves conformal gravity global quadratic potential
2010/12/21
We apply the conformal gravity theory to a sample of 110 spiral galaxies whose rotation curve
data points extend well beyond the optical disk. With no free parameters other than galactic mass to ligh...

Fitting galactic rotation curves conformal gravity quadratic potential
2010/12/27
We apply the conformal gravity theory to a sample of 110 spiral galaxies whose rotation curve data points extend well beyond the optical disk. With no free parameters other than galactic mass to ligh...
This paper discusses the observed flat rotation curves of galaxies in the context of noncommutative geometry. The energy density of such a geometry is diffused throughout a region due to the uncertain...
Relativistic redshift effects and the Galactic-center stars
Relativistic redshift Galactic-center stars
2010/3/17
The high pericenter velocities (up to a few percent of light) of the S stars around the Galactic-center black hole suggest that general relativistic effects may be detectable through the time variatio...
Perspective of Galactic dark matter subhalo detection on Fermi from the EGRET observation
dark matter substructures gamma-rays Fermi telescope
2009/9/9
The perspective of the detectability of Galactic dark matter subhaloes on the Fermi satellite is investigated in this work. Under the assumptions that dark matter annihilation accounts for the ``GeV e...
