Searching for primordial localized features with CMB and LSS spectra
Bin Hu, Jesús Torrado
Inspired by the study of mild transient reductions in the speed of sound of the adiabatic mode during inflation, we search for a primordial localized feature imprinted in cosmic mi…

Inflation with moderately sharp features in the speed of sound: GSR and in-in formalism for power spectrum and bispectrum
Ana Achucarro, Vicente Atal, Bin Hu +2
We continue the study of mild transient reductions in the speed of sound of the adiabatic mode during inflation, of their effect on the primordial power spectrum and bispectrum, an…
