Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021

Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang +118

Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probe…

Comparing multi-field primordial feature models with the Planck data

Matteo Braglia, Xingang Chen, Dhiraj Kumar Hazra

In this paper, we use a complete model of classical primordial standard clocks as an example to develop a methodology of directly comparing numerical predictions from complicated m…

Probing Primordial Features with the Stochastic Gravitational Wave Background

Matteo Braglia, Xingang Chen, Dhiraj Kumar Hazra

The stochastic gravitational wave background (SGWB) offers a new opportunity to observe signals of primordial features from inflationary models. We study their detectability with f…

Inflation Wars: A New Hope

Ryan E. Keeley, Arman Shafieloo, Dhiraj Kumar Hazra +1

We explore a class of primordial power spectra that can fit the observed anisotropies in the cosmic microwave background well and that predicts a value for the Hubble parameter con…

Extended reionization in models beyond CDM with Planck 2018 data

Daniela Paoletti, Dhiraj Kumar Hazra, Fabio Finelli +1

We provide an update on the constraints on extended reionization histories with the Planck 2018 cosmic microwave background anisotropy data. The Planck 2018 data on large angular s…
