Primary gravitational waves at high frequencies II: Emergence of the exponential cut-off in the power spectrum
Alipriyo Hoory, Jerome Martin, Arnab Paul +1
[Abridged] In slow roll inflation, the power spectrum (PS) of primary gravitational waves (PGWs) generated from the quantum vacuum rises as over wave numbers which never…

Reconstructing inflationary features on large scales using genetic algorithm
Alipriyo Hoory, Dhiraj Kumar Hazra, L. Sriramkumar
[Abridged] A variety of model-dependent as well as model-independent approaches suggest that certain localized features in the primordial scalar power spectrum can lead to a signif…

Primary gravitational waves at high frequencies I: Origin of suppression in the power spectrum
Alipriyo Hoory, Jerome Martin, Arnab Paul +1
[Abridged] The primary gravitational waves (PGWs) are generated in the early universe from the quantum vacuum during inflation. In slow roll inflation, the power spectrum (PS) of P…
