Dark Matter at the Center and in the Halo of the Galaxy
Neven Bilic, Gary B. Tupper, Raoul D. Viollier
All presently known stellar-dynamical constraints on the size and mass of the supermassive compact dark object at the Galactic center are consistent with a ball of self-gravitating…
Inhomogeneous Chaplygin Gas Cosmology
Neven Bilic, Robert J. Lindebaum, Gary B. Tupper +1
The hypothesis that dark matter and dark energy are unified through the Chaplygin gas is reexamined. Using a generalization of the spherical model which incorporates effects of the…
Supermassive fermion balls and constraints from stellar dynamics near Sgr A*
Neven Bilic, Gary B Tupper, Raoul D Viollier
All presently known stellar-dynamical constraints on the size and mass of the supermassive compact dark object at the Galactic center are consistent with a ball of self-gravitating…
Comparison of the Black Hole and Fermion Ball Scenarios of the Galactic Center
Neven Bilic, Faustin Munyaneza, Gary B. Tupper +1
After discussion of the properties of degenerate fermion balls, we analyze the orbit of the star S0-1, which has a projected distance of ~5 light-days to Sgr A*, in the supermassiv…
Dark Matter, Dark Energy and the Chaplygin Gas
Neven Bilic, Gary B. Tupper, Raoul D. Viollier
We formulate a Zel'dovich-like approximation for the Chaplygin gas equation of state P = -A/rho, and sketch how this model unifies dark matter with dark energy in a geometric setti…
Does Dark Matter at the Center and in the Halo of the Galaxy Consist of the Same Particles?
Neven Bilic, Faustin Munyaneza, Gary B. Tupper +1
After a discussion of the properties od degenerate fermion balls, we analize the orbits of the star S0-1, which has the smallest projected distance to Sgr A*, in the supermassive b…
