High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization
Rennan Barkana, Oliver Basquette, Ankita Bera +22
In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…
Minkowski Functionals of the 21 cm Signal as a Probe of Primordial Features
Kanan Virkar, Suvedha Suresh Naik, Pravabati Chingangbam
The redshifted 21 cm signal from the cosmic dawn and Epoch of Reionization (EoR) encodes important information about both astrophysical processes and primordial physics, such as in…
Global 21 cm signal: a promising probe of primordial features
Suvedha Suresh Naik, Pravabati Chingangbam, Saurabh Singh +2
Inflationary models that involve bursts of particle production generate bump-like features in the primordial power spectrum of density perturbations. These features influence the e…
Extra-Natural Inflation (De)constructed
Kazuyuki Furuuchi, Noel Jonathan Jobu, Suvedha Suresh Naik
Extra-natural inflation is (de)constructed. Explicit models are compared with cosmological observations. The models successfully achieve trans-Planckian inflaton field excursions.
Large Field Excursions from Dimensional (De)construction
Kazuyuki Furuuchi, Suvedha Suresh Naik, Noel Jonathan Jobu
An inflation model based on dimensional (de)construction of a massive gauge theory is proposed. The inflaton in this model is the "zero-mode" of a component of the massive gauge fi…
