GCG Parametrization for Growth Function and Current Constraints
Gaveshna Gupta, Somasri Sen, Anjan A. Sen
We study the linear growth function for large scale structures in a cosmological scenario where Generalised Chaplygin Gas (GCG) serves as dark energy candidate. We parametrize…
Constraining Thawing Quintessence
Gaveshna Gupta, Subhabrata Majumdar, Anjan A Sen
We look at observational constraints on the thawing class of scalar field models proposed to explain the late time acceleration of the universe. Using the recently introduced `Stat…
Observational Constraints on Axions as Quintessence in String Theory
Gaveshna Gupta, Sudhakar Panda, Anjan A Sen
We study the observational constraints for the axion models in string theory which can successfully act as quintessence. The evolution of the universe in this model is sensitive to…
