Detecting Cosmological Stasis with Future Gravitational Wave Observatories
Gabriela Barenboim, Anne-Katherine Burns
We map the observational predictions of cosmological stasis in the inflationary gravitational wave background onto the sensitivity bands of current and planned gravitational wave d…
Gravitational Wave Signatures of Cosmological Stasis: A Unified Spectral Template
Gabriela Barenboim, Anne-Katherine Burns
Proposed in 2022 by Dienes et al., stasis is a dynamical fixed point in the early universe in which the equation of state, , is fixed at a constant value. In this study we sho…
Temperature-Dependent CPT Violation: Constraints from Big Bang Nucleosynthesis
Gabriela Barenboim, Anne-Katherine Burns
In this study, we explore temperature-dependent CPT violation during Big Bang Nucleosynthesis (BBN) through electron-positron mass asymmetries parametrized by . The…
Inside the Black Box of Big Bang Nucleosynthesis: A Comprehensive Sensitivity Atlas for the Precision Era
Anne-Katherine Burns
In this study we present a comprehensive sensitivity atlas for Big Bang Nucleosynthesis (BBN) in which we quantify the dependence of the primordial abundances of helium-4, deuteriu…
Seafloor Topography Enhances KM3NeT Sensitivity to ANITA-like Events
Carlos A. Argüelles, Toni Bertólez-MartÃnez, Alba Burgos-Mondéjar +3
In this article, we introduce the concept of \textit{topographic enhancement} in the context of ultra-high-energy neutrino detection by underwater neutrino telescopes. We demonstra…
Constraints on Variation of the Weak Scale from Big Bang Nucleosynthesis
Anne-Katherine Burns, Venus Keus, Marc Sher +1
Recently, the EMPRESS collaboration has included new data in the extraction of the primordial He abundance from Big Bang Nucleosynthesis (BBN), resulting in a determination tha…
