The Limits of Extended Quintessence
S. Nesseris, L. Perivolaropoulos
We use a low redshift expansion of the cosmological equations of extended (scalar-tensor) quintessence to divide the observable Hubble history parameter space in four sectors: A fo…

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…

Accelerating Universe: Observational Status and Theoretical Implications
L. Perivolaropoulos
This is a pedagogical review of the recent observational data obtained from type Ia supernova surveys that support the accelerating expansion of the universe. The methods for the a…
