Rotating black hole solutions for gravity and Newman Janis Algorithm
Pankaj Chaturvedi, Utkarsh Kumar, Udaykrishna Thattarampilly +1
We show that the -gravity theories with constant Ricci scalar in the Jordan/Einstein frame can be described by Einstein or Einstein-Maxwell gravity with a cosmological term a…
Requiem to "Proof of Inflation" or Sourced Fluctuations in a Non-Singular Bounce
Ido Ben-Dayan, Udaykrishna Thattarampilly
Popular wisdom suggests that measuring the tensor to scalar ratio on CMB scales is a "proof of inflation" since one generic prediction is a scale-invariant tensor spectrum whil…
Probing The Early Universe Cosmology With NANOGrav: Possibilities and Limitations
Ido Ben-Dayan, Utkarsh Kumar, Udaykrishna Thattarampilly +1
A stochastic gravitational wave background is a prediction of a number of astrophysical and cosmological phenomena including early Universe Cosmology. Recently, the NANOGrav Collab…
