Not R Kurvature: Beating Large-Scale White Noise
Wayne Hu
Kurvature, a recently identified curvature invariant, has been argued to acquire superhorizon, or large-scale, white noise from hard-hard momentum coupling even when matter nonline…
Raising the reionization optical depth with inflationary CMB features
Tanisha Jhaveri, Wayne Hu, Vivian Miranda
Within the highly successful CDM paradigm established with cosmic microwave background (CMB) anisotropy measurements, the optical depth through reionization is the most un…
Machine Learning Assisted Parameter-Space Searches for Lensed Gravitational Waves
Giulia Campailla, Marco Raveri, Wayne Hu +1
When a gravitational wave encounters a massive object along the line of sight, repeated copies of the original signal may be produced due to gravitational lensing. In this paper, w…
Turning a negative neutrino mass into a positive optical depth
Tanisha Jhaveri, Tanvi Karwal, Wayne Hu
Under CDM, recent baryon acoustic oscillation (BAO) distance measures from DESI, which favor a low matter density , are in moderate tension with cosmic microwave…
Testing Gravity with Realistic Gravitational Waveforms in Pulsar Timing Arrays
Wayne Hu, Qiuyue Liang, Meng-Xiang Lin +1
We consider the effects of relaxing the assumption that gravitational waves composing the stochastic gravitational wave background (SGWB) are uncorrelated between frequencies in an…
