A theoretician's analysis of the supernova data and the limitations in determining the nature of dark energy
T. Padmanabhan, T. Roy Choudhury
Current cosmological observations show a strong signature of the existence of a dark energy component with negative pressure. The most obvious candidate for this dark energy is the…

Can the clustered dark matter and the smooth dark energy arise from the same scalar field ?
T. Padmanabhan, T. Roy Choudhury
Cosmological observations suggest the existence of two different kinds of energy densities dominating at small ( Mpc) and large ( Mpc) scales. The dar…

Probing the dark ages with redshift distribution of GRBs
T. Roy Choudhury, R. Srianand
In this article, we explore the possibility of using the properties of gamma ray bursts (GRBs) to probe the physical conditions in the epochs prior to reionization. The redshift di…
