Accuracy of slow-roll formulae for inflationary perturbations: implications for primordial black hole formation
Sirichai Chongchitnan, George Efstathiou
We investigate the accuracy of the slow-roll approximation for calculating perturbation spectra generated during inflation. The Hamilton-Jacobi formalism is used to evolve inflatio…
The Search For Primordial Tensor Modes
George Efstathiou, Sirichai Chongchitnan
We review the prospects for detecting tensor modes generated during inflation by CMB polarization experiments and by searching for a stochastic gravitational wave background with l…
Prospects for direct detection of primordial gravitational waves
Sirichai Chongchitnan, George Efstathiou
We study the primordial gravitational wave background produced in models of single field inflation. Using the inflationary flow approach, we investigate the amplitude of gravitatio…
