Constraining Thawing Dark Energy using Galaxy Cluster Number Counts
N. Chandrachani Devi, T. Roy Choudhury, Anjan A. Sen
We study the formation of galaxy clusters in the presence of thawing class of scalar field dark energy. We consider cases where the scalar field has canonical as well non canonical…
WMAP Constraints On K-Inflation
N. Chandrachani Devi, Akhilesh Nautiyal, Anjan A Sen
We study the K-Inflation models where the inflaton field has non-canonical kinetic term. In particular, we consider the Dirac-Born-Infeld (DBI) form for the kinetic energy of the i…
Solar System Constraints on Scalar Tensor Theories with Non-Standard Action
N. Chandrachani Devi, Sudhakar Panda, Anjan A Sen
We compute the Post-Newtonian parameter (PPN),, for scalar-tensor gravity theory when the action functional for the scalar field is a non-standard one, namely the Dirac-Born-Inf…
