Tension and Systematics in the Gold06 SnIa Dataset
S. Nesseris, L. Perivolaropoulos
The Gold06 SnIa dataset recently released in astro-ph/0611572 consists of five distinct subsets defined by the group or instrument that discovered and analyzed the corresponding da…
Evolving Newton's Constant, Extended Gravity Theories and SnIa Data Analysis
S. Nesseris, L. Perivolaropoulos
If Newton's constant G evolves on cosmological timescales as predicted by extended gravity theories then Type Ia supernovae (SnIa) can not be treated as standard candles. The magni…
Comparison of the Legacy and Gold SnIa Dataset Constraints on Dark Energy Models
S. Nesseris, L. Perivolaropoulos
We have performed a comparative analysis of three recent and reliable SnIa datasets available in the literature: the Full Gold (FG) dataset (157 data points ), a Truncate…
The Fate of Bound Systems in Phantom and Quintessence Cosmologies
S. Nesseris, L. Perivolaropoulos
We study analytically and numerically the evolution of bound systems in universes with accelerating expansion where the acceleration either increases with time towards a Big Rip si…
