Current and Future Constraints on the Primordial Power Spectrum
Zachary Cheslog, Emily Finson, Amanda MacInnis +4
The primordial scalar power spectrum provides a powerful window onto early-universe physics, including a broad class of inflationary scenarios. These models often predict a charact…

Constraining primordial oscillations and inflationary particle production with Planck, ACT DR6, and DESI DR2
Simran K. Nerval, Renee Hlozek, Hidde T. Jense +1
Non-standard inflationary models often predict oscillatory features in the primordial power spectrum. We present constraints on general oscillatory templates for primordial power s…
