CosmoSIS: modular cosmological parameter estimation
Joe Zuntz, Marc Paterno, Elise Jennings +6
Cosmological parameter estimation is entering a new era. Large collaborations need to coordinate high-stakes analyses using multiple methods; furthermore such analyses have grown i…
Neutrinos help reconcile Planck measurements with both Early and Local Universe
Cora Dvorkin, Mark Wyman, Douglas H. Rudd +1
In light of the recent BICEP2 B-mode polarization detection, which implies a large inflationary tensor-to-scalar ratio r_{0.05}=0.2^{+0.07}_{-0.05}, we re-examine the evidence for…
Weighing Galaxy Clusters with Gas. II. On the Origin of Hydrostatic Mass Bias in LambdaCDM Galaxy Clusters
Kaylea Nelson, Erwin T. Lau, Daisuke Nagai +2
The use of galaxy clusters as cosmological probes hinges on our ability to measure their masses accurately and with high precision. Hydrostatic mass is one of the most common metho…
CDM: Neutrinos help reconcile Planck with the Local Universe
Mark Wyman, Douglas H. Rudd, R. Ali Vanderveld +1
Current measurements of the low and high redshift Universe are in tension if we restrict ourselves to the standard six parameter model of flat CDM. This tension has two parts. F…
Predicting Merger-Induced Gas Motions in Lambda-CDM Galaxy Clusters
Daisuke Nagai, Erwin T. Lau, Camille Avestruz +2
In the hierarchical structure formation model, clusters of galaxies form through a sequence of mergers and continuous mass accretion, which generate significant random gas motions…
Evolution of the Merger Induced Hydrostatic Mass Bias in Galaxy Clusters
Kaylea Nelson, Douglas H. Rudd, Laurie Shaw +1
In this work, we examine the effects of mergers on the hydrostatic mass estimate of galaxy clusters using high-resolution Eulerian cosmological simulations. We utilize merger trees…
