Non-thermal Sunyaev-Zeldovich signal from radio galaxy lobes
Sandeep Kumar Acharya, Subhabrata Majumdar, Biman B. Nath
Energetic electrons in the lobes of radio galaxies make them potential sources for not only radio and X-rays but also Sunyaev-Zeldovich (SZ) distortions in the cosmic microwave bac…
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…
Thermalization of large energy release in the early Universe
Jens Chluba, Andrea Ravenni, Sandeep Kumar Acharya
Spectral distortions of the cosmic microwave background (CMB) provide a unique tool for learning about the early phases of cosmic history, reaching deep into the primordial Univers…
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…
