Planck Constraints and Gravitational Wave Forecasts for Primordial Black Hole Dark Matter Seeded by Multifield Inflation
Wenzer Qin, Sarah R. Geller, Shyam Balaji +2
We perform a Markov Chain Monte Carlo (MCMC) analysis of a simple yet generic multifield inflation model characterized by two scalar fields coupled to each other and nonminimally c…
Observing nulling of primordial correlations via the 21 cm signal
Shyam Balaji, H. V. Ragavendra, Shiv K. Sethi +2
The 21cm line emitted by neutral hydrogen (HI) during the Dark Ages carries imprints of pristine primordial correlations. In models of inflation driven by a single, canonical scala…
Induced gravitational waves from slow-roll inflation after an enhancing phase
Shyam Balaji, Guillem Domenech, Joseph Silk
The primordial spectrum of fluctuations may present a large peak as a result of enhancing features during inflation. This may include, but is not limited to, bumps in the inflaton'…
Radio sky reveals primordial electron-proton interactions
Shyam Balaji, Maura E. Ramirez-Quezada, Celine Boehm
For several decades, astronomers have measured the electromagnetic emission in the universe from the lowest to the highest energies with incredible precision. The lowest end of the…
Induced gravitational waves from the cosmic coincidence
Shyam Balaji, Joseph Silk, Yi-Peng Wu
The induced gravitational wave (GW) background from enhanced primordial scalar perturbations is one of the most promising observational consequences of primordial black hole (PBH)…
