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…
Gravitational waves from asymmetric oscillon dynamics?
Mustafa A. Amin, Jonathan Braden, Edmund J. Copeland +4
It has been recently suggested that oscillons produced in the early universe from certain asymmetric potentials continue to emit gravitational waves for a number of -folds of ex…
Constraining cosmological ultra-large scale structure using numerical relativity
Jonathan Braden, Matthew C. Johnson, Hiranya V. Peiris +1
Cosmic inflation, a period of accelerated expansion in the early universe, can give rise to large amplitude ultra-large scale inhomogeneities on distance scales comparable to or la…
Cosmic bubble and domain wall instabilities III: The role of oscillons in three-dimensional bubble collisions
J. Richard Bond, Jonathan Braden, Laura Mersini-Houghton
We study collisions between pairs of bubbles nucleated in an ambient false vacuum. For the first time, we include the effects of small initial (quantum) fluctuations around the ins…
Testing Inflation with Large Scale Structure: Connecting Hopes with Reality
Marcelo Alvarez, Tobias Baldauf, J. Richard Bond +25
The statistics of primordial curvature fluctuations are our window into the period of inflation, where these fluctuations were generated. To date, the cosmic microwave background h…
