Stasis Combs: Gravitational-Wave Signatures of Recurrent Cosmological Stasis
Gabriela Barenboim, Anne-Katherine Burns
Cosmological stasis can recur multiple times, and each occurrence imprints a characteristic feature on the inflationary gravitational wave background (IGWB). We extend the single-e…
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…
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…
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…
Seafloor Topography Enhances KM3NeT Sensitivity to ANITA-like Events
Carlos A. Argüelles, Toni Bertólez-Martínez, Alba Burgos-Mondéjar +3
In this article, we introduce the concept of topographic enhancement in the context of ultra-high-energy neutrino detection by underwater neutrino telescopes. We demonstrate that t…
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…
PRyMordial: The First Three Minutes, Within and Beyond the Standard Model
Anne-Katherine Burns, Tim M. P. Tait, Mauro Valli
In this work we present PRyMordial: A package dedicated to efficient computations of observables in the Early Universe with the focus on the cosmological era of Big Bang Nucleosynt…
Indications for a Nonzero Lepton Asymmetry from Extremely Metal-Poor Galaxies
Anne-Katherine Burns, Tim M. P. Tait, Mauro Valli
The recent measurement of helium-4 from the near-infrared spectroscopy of extremely metal-poor galaxies (EMPGs) by the Subaru Survey may point to a new puzzle in the Early Universe…
Time Evolution in Quantum Cosmology
Anne-Katherine Burns, David E. Kaplan, Tom Melia +1
The quantum description of time evolution in non-linear gravitational systems such as cosmological space-times is not well understood. We show, in the simplified setting of mini-su…
Dark Matter Interpretation of the Fermi-LAT Observations Toward the Outer Halo of M31
Chris Karwin, Simona Murgia, Igor Moskalenko +3
An excess -ray signal toward the outer halo of M31 has recently been reported. Although other explanations are plausible, the possibility that it arises from dark matter (DM) is…
On Dark Matter Explanations of the Gamma-Ray Excesses from the Galactic Center and M31
Anne-Katherine Burns, Max Fieg, Christopher M. Karwin +1
The presence of an excess gamma-ray signal toward the Galactic center (GC) has now been well established, and is known as the GC excess. Leading explanations for the signal include…
