Constraints on of high energy non-thermal neutrino injections upto from CMB spectral distortions and abundance of light elements

Sandeep Kumar Acharya, Rishi Khatri

High energy neutrinos and anti-neutrinos ( 100 GeV) can inject energetic electromagnetic particles into the baryon-photon plasma in the high redshift universe through elec…

CMB and BBN constraints on evaporating primordial black holes revisited

Sandeep Kumar Acharya, Rishi Khatri

We derive new CMB anisotropy power spectrum and BBN constraints for evaporating primordial black holes by explicitly solving the electromagnetic particle cascades of emitted partic…

Detection of WHIM in the Planck data using Stack First approach

Baibhav Singari, Tuhin Ghosh, Rishi Khatri

We detect the diffuse thermal Sunyaev-Zeldovich (tSZ) effect from the gas filaments between the Luminous Red Galaxy (LRG) pairs using a new approach relying on stacking the individ…
