Precision cosmology with voids in the final BOSS data
Nico Hamaus, Alice Pisani, Jin-Ah Choi +3
We report novel cosmological constraints obtained from cosmic voids in the final BOSS DR12 dataset. They arise from the joint analysis of geometric and dynamic distortions of avera…
Inferring the Age of the Universe with Globular Clusters
David Valcin, José Luis Bernal, Raul Jimenez +2
We present an estimate of the absolute age of 68 galactic globular clusters obtained by exploiting the distribution of stars in the full color-magnitude diagram. In particular, we…
Accurate precision Cosmology with redshift unknown gravitational wave sources
Suvodip Mukherjee, Benjamin D. Wandelt, Samaya M. Nissanke +1
Gravitational waves can provide an accurate measurement of the luminosity distance to the source, but cannot provide the source redshift unless the degeneracy between mass and reds…
Inferring the lensing rate of LIGO-Virgo sources from the stochastic gravitational wave background
Suvodip Mukherjee, Tom Broadhurst, Jose M. Diego +2
Strong lensing of gravitational waves is more likely for distant sources but predicted event rates are highly uncertain with many astrophysical origins proposed. Here we open a new…
Inevitable imprints of patchy reionization on the cosmic microwave background anisotropy
Sourabh Paul, Suvodip Mukherjee, Tirthankar Roy Choudhury
Reionization of the cosmic neutral hydrogen by the first stars in the Universe is an inhomogeneous process which produces spatial fluctuations in free electron density. These fluct…
Perfectly parallel cosmological simulations using spatial comoving Lagrangian acceleration
Florent Leclercq, Baptiste Faure, Guilhem Lavaux +5
Existing cosmological simulation methods lack a high degree of parallelism due to the long-range nature of the gravitational force, which limits the size of simulations that can be…
