Counting voids to probe dark energy
Alice Pisani, P. M. Sutter, Nico Hamaus +4
We show that the number of observed voids in galaxy redshift surveys is a sensitive function of the equation of state of dark energy. Using the Fisher matrix formalism we find the…
How to detect gravitational waves through the cross-correlation of the galaxy distribution with the CMB polarization
Esfandiar Alizadeh, Christopher M. Hirata
Thompson scattering of cosmic microwave background (CMB) photons off of free electrons during the reionization epoch induces a correlation between the distribution of galaxies and…
Molecular hydrogen in the cosmic recombination epoch
Esfandiar Alizadeh, Christopher M. Hirata
The advent of precise measurements of the cosmic microwave background (CMB) anisotropies has motivated correspondingly precise calculations of the cosmic recombination history. Cos…
Voids as a Precision Probe of Dark Energy
Rahul Biswas, Esfandiar Alizadeh, Benjamin D. Wandelt
A signature of the dark energy equation of state may be observed in the shape of voids. We estimate the constraints on cosmological parameters that would be determined from the ell…
Dark matter halo merger and accretion probabilities in the excursion set formalism
Esfandiar Alizadeh, Benjamin Wandelt
The merger and accretion probabilities of dark matter halos have so far only been calculated for an infinitesimal time interval. This means that a Monte-Carlo simulation with very…
