Luminosity distance in "Swiss cheese" cosmology with randomized voids: I. Single void size
R. Ali Vanderveld, Eanna E. Flanagan, Ira Wasserman
Recently there have been suggestions that the Type Ia supernova data can be explained using only general relativity and cold dark matter with no dark energy. In "Swiss cheese" mode…
Quantifying parameter errors due to the peculiar velocities of type Ia supernovae
R. Ali Vanderveld
The fitting of the observed redshifts and magnitudes of type Ia supernovae to what we would see in homogeneous cosmological models has led to constraints on cosmological parameters…
Systematic corrections to the measured cosmological constant as a result of local inhomogeneity
R. Ali Vanderveld, Eanna E. Flanagan, Ira Wasserman
We calculate the systematic inhomogeneity-induced correction to the cosmological constant that one would infer from an analysis of the luminosities and redshifts of Type Ia superno…
Mimicking Dark Energy with Lemaitre-Tolman-Bondi Models: Weak Central Singularities and Critical Points
R. Ali Vanderveld, Eanna E. Flanagan, Ira Wasserman
There has been much debate over whether or not one could explain the observed acceleration of the Universe with inhomogeneous cosmological models, such as the spherically-symmetric…
Spherical Gravitational Collapse of Annihilating Dark Matter and the Minimum Mass of CDM Black Holes
R. Ali Vanderveld, Ira Wasserman
Spherical gravitational collapse of a cold gas of annihilating particles involves a competition between the free-fall rate and the (s-wave) annihilation rate $\prop…
