Observational constraints on quintessence models of dark energy
Archana Sangwan, Ashutosh Tripathi, H. K. Jassal
Scalar fields aptly describe equation of state of dark energy. The scalar field models were initially proposed to circumvent the fine tuning problem of cosmological constant. Howev…

Dark energy equation of state parameter and its variation at low redshifts
Ashutosh Tripathi, Archana Sangwan, H. K. Jassal
In this paper, we constrain dark energy models using a compendium of observations at low redshifts. We consider the dark energy as a barotropic fluid, with the equation of state a…
