Free-streaming and Coupled Dark Radiation Isocurvature Perturbations: Constraints and Application to the Hubble Tension
Subhajit Ghosh, Soubhik Kumar, Yuhsin Tsai
Dark radiation (DR) appears as a new physics candidate in various scenarios beyond the Standard Model. While it is often assumed that perturbations in DR are adiabatic, they can ea…

Dark neutrino interactions make gravitational waves blue
Subhajit Ghosh, Rishi Khatri, Tuhin S. Roy
New interactions of neutrinos can stop them from free streaming in the early Universe even after the weak decoupling epoch. This results in the enhancement of the primordial gravit…
