Primordial blackhole formation: Exploring chaotic potential with a sharp step via the GLMS perspective
Rinsy Thomas, Jobil Thomas, Minu Joy
A sharp step on a chaotic potential can enhance primordial curvature fluctuations on smaller scales to the to form primordial black holes (PBHs). The present…
Gravitational wave production after inflation for a hybrid inflationary model
Rinsy Thomas, Jobil Thomas, Supin P Surendran +1
We discuss a cosmological scenario with a stochastic background of gravitational waves sourced by the tensor perturbation due to a hybrid inflationary model with cubic potential. T…
From the Spectrum to Inflation: A Second Order Inverse Formula for the General Slow-Roll Spectrum
Minu Joy, Ewan D. Stewart
We invert the second order, single field, general slow-roll formula for the power spectrum, to obtain a second order formula for inflationary parameters in terms of the primordial…
From the Spectrum to Inflation : An Inverse Formula for the General Slow-Roll Spectrum
Minu Joy, Ewan D. Stewart, Jinn-Ouk Gong +1
We propose a general inverse formula for extracting inflationary parameters from the observed power spectrum of cosmological perturbations. Under the general slow-roll scheme, whic…
