Testing LCDM with the Growth Function δ(a): Current Constraints
S. Nesseris, L. Perivolaropoulos
We have compiled a dataset consisting of 22 datapoints at a redshift range (0.15,3.8) which can be used to constrain the linear perturbation growth rate f=\frac{d\lnδ}{d\ln a}. Fiv…

Cosmic Acceleration Data and Bulk-Brane Energy Exchange
C. Bogdanos, S. Nesseris, L. Perivolaropoulos +1
We consider a braneworld model with bulk-brane energy exchange. This allows for crossing of the w=-1 phantom divide line without introducing phantom energy with quantum instabiliti…

Can f(R) Modified Gravity Theories Mimic a LCDM Cosmology?
S. Fay, S. Nesseris, L. Perivolaropoulos
We consider f(R) modified gravity theories in the metric variation formalism and attempt to reconstruct the function f(R) by demanding a background LCDM cosmology. In particular we…
