Alleviating the Tension in the Cosmic Microwave Background using Planck-Scale Physics
Abhay Ashtekar, Brajesh Gupt, Donghui Jeong +1
Certain anomalies in the CMB bring out a tension between the six-parameter flat CDM model and the CMB data. We revisit the PLANCK analysis with loop quantum cosmology (LQC) pred…

Constraining Planck scale physics with CMB and Reionization Optical Depth
Brajesh Gupt
We present proof of principle for a two way interplay between physics at very early Universe and late time observations. We find a relation between primordial mechanisms responsibl…

Tensor perturbations during inflation in a spatially closed Universe
Béatrice Bonga, Brajesh Gupt, Nelson Yokomizo
In a recent paper [17], we studied the evolution of the background geometry and scalar perturbations in an inflationary, spatially closed Friedmann-Lemaître-Robertson-Walker (FLRW)…
