Revisiting dark energy models using differential ages of galaxies
Nisha Rani, Deepak Jain, Shobhit Mahajan +2
In this work, we use a test based on the differential ages of galaxies for distinguishing the dark energy models. As proposed by Jimenez and Loeb, relative ages of galaxies can be…
Constraining cosmic curvature by using age of galaxies and gravitational lenses
Akshay Rana, Deepak Jain, Shobhit Mahajan +1
We use two model-independent methods to constrain the curvature of the universe. In the first method, we study the evolution of the curvature parameter () with redshift by u…
Reheating constraints on Kähler Moduli Inflation
R. Kabir, A. Mukherjee, D. Lohiya
The end of inflation is connected to the standard cosmological scenario through reheating. During reheating, the inflaton oscillates around the minimum of the potential and thus de…
Reanalyzing the upper limit on the tensor-to-scalar perturbation ratio r_T in a quartic potential inflationary model
R. Kabir, A. Mukherjee, D. Lohiya
We study the polynomial chaotic inflation model with a single scalar field in a double well quartic potential which has recently been shown to be consistent with Planck data. In pa…
