The Impact of Peculiar Velocities on the Estimation of the Hubble Constant from Gravitational Wave Standard Sirens
Constantina Nicolaou, Ofer Lahav, Pablo Lemos +2
In this work we investigate the systematic uncertainties that arise from the calculation of the peculiar velocity when estimating the Hubble constant () from gravitational wav…

Target Neutrino Mass Precision for Determining the Neutrino Hierarchy
Constance Mahony, Boris Leistedt, Hiranya V. Peiris +5
Recent works combining neutrino oscillation and cosmological data to determine the neutrino hierarchy found a range of odds in favour of the normal hierarchy. These results arise f…

Nonlinear Dynamics of the Cold Atom Analog False Vacuum
Jonathan Braden, Matthew C. Johnson, Hiranya V. Peiris +2
We investigate the nonlinear dynamics of cold atom systems that can in principle serve as quantum simulators of false vacuum decay. The analog false vacuum manifests as a metastabl…
