From Fluctuation to Polarization: Imprints of Curvature Perturbations in CMB B-modes from Scalar-Induced Gravitational Waves
Aurora Ireland, Kuver Sinha, Tao Xu
Probing primordial curvature perturbations on small scales, beyond those accessible using cosmic microwave background (CMB) primary anisotropies and Lyman- forest data, remains…
Supernova-Boosted Dark Matter at Large-Volume Neutrino Detectors
Badal Bhalla, Fazlollah Hajkarim, Doojin Kim +1
Core-collapse supernovae, among the universe's most energetic events, offer a novel window into the dark sector by potentially producing a flux of boosted dark matter (BDM). We exp…
Cosmological Moduli and Non-perturbative Production of Axions
Robert Wiley Deal, Leia Barrowes, John T. Giblin +3
Cosmological moduli generically come to dominate the energy density of the early universe, and thereby trigger an early matter dominated era. Such non-standard cosmological histori…
Blue Loops, Cepheids, and Forays into Axions
Kaleb Anderson, Thomas C. Gehrman, Pearl Sandick +3
The blue loop stage of intermediate mass stars has been called a "magnifying glass", where even seemingly small effects in prior stages of evolution, as well as assumptions about s…
Conversations and Deliberations: Non-Standard Cosmological Epochs and Expansion Histories
Brian Batell, Keith R. Dienes, Brooks Thomas +17
This document summarizes the discussions which took place during the PITT-PACC Workshop entitled "Non-Standard Cosmological Epochs and Expansion Histories," held in Pittsburgh, Pen…
