Constraint on noncommutative spacetime from PLANCK data
Joby P. K., Pravabati Chingangbam, Subinoy Das
We constrain the energy scale of noncommutativity of spacetime using CMB data from PLANCK. We find that PLANCK data puts the lower bound on the noncommutativity energy scale to abo…

Primordial non-Gaussian signatures in CMB polarization
Vidhya Ganesan, Pravabati Chingangbam, K. P. Yogendran +1
We study the signatures of local type primordial non-Gaussianity, parametrized by $\fnl$, of scalar perturbations in CMB polarization using the probability distribution functions,…

New features in curvaton model
Pravabati Chingangbam, Qing-Guo Huang
We demonstrate novel features in the behavior of the second and third order non-linearity parameters of the curvature perturbation, namely, and , arising from non-…
