Gravitational Waves as a Source of Large-Scale White Noise: New Constraints
Gabriela Barenboim, Albert Stebbins
The paper shows how a stochastic gravitational‑wave background can generate large‑scale white noise in the cosmic density field and uses the lack of observed white noise to place l…
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…
When CPT Violation Hides in Plain Sight: How CP Measurements Are Compromised and How to Fix Them
Miaochen Jin, Gabriela Barenboim, Carlos A. Argüelles +2
The extraction of the leptonic charge-parity (CP)-violating phase from long-baseline neutrino oscillation experiments rests on the assumption of charge-parity-time (C…
Are neutrinos Majorana? Fixed-target and high-energy astrophysical searches decide
Gabriela Barenboim, Mauricio Bustamante, Qinrui Liu
Determining whether the neutrino is a Dirac or Majorana fermion remains a fundamental open question. Conventional searches rely on neutrinoless double beta decay, but this electron…
Large Scale White Noise and Cosmology
Gabriela Barenboim, Aurora Ireland, Albert Stebbins
The generation of white noise on large scales is a generic property of the dynamics of physical systems described by local non-linear partial differential equations. Non-linearitie…
