The Mira-Titan Universe: Precision Predictions for Dark Energy Surveys

Katrin Heitmann, Derek Bingham, Earl Lawrence +8

Ground and space-based sky surveys enable powerful cosmological probes based on measurements of galaxy properties and the distribution of galaxies in the Universe. These probes inc…

The Q Continuum Simulation: Harnessing the Power of GPU Accelerated Supercomputers

Katrin Heitmann, Nicholas Frontiere, Chris Sewell +6

Modeling large-scale sky survey observations is a key driver for the continuing development of high resolution, large-volume, cosmological simulations. We report the first results…

CMB Lensing Power Spectrum Biases from Galaxies and Clusters using High-angular Resolution Temperature Maps

A. van Engelen, S. Bhattacharya, N. Sehgal +3

The lensing power spectrum from cosmic microwave background (CMB) temperature maps will be measured with unprecedented precision with upcoming experiments, including upgrades to AC…

A direct measurement of the linear bias of mid-infrared-selected quasars at z~1 using cosmic microwave background lensing

J. E. Geach, R. C. Hickox, L. E. Bleem +52

We measure the cross-power spectrum of the projected mass density as traced by the convergence of the cosmic microwave background lensing field from the South Pole Telescope (SPT)…

Cosmic Emulation: The Concentration-Mass Relation for wCDM Universes

Juliana Kwan, Suman Bhattacharya, Katrin Heitmann +1

The concentration-mass relation for dark matter-dominated halos is one of the essential results expected from a theory of structure formation. We present a simple prediction scheme…

Bispectrum of the Sunyaev-Zel'dovich Effect

Suman Bhattacharya, Daisuke Nagai, Laurie Shaw +2

We perform a detailed study of the bispectrum of the Sunyaev-Zel'dovich effect. Using an analytical model for the pressure profiles of the intracluster medium, we demonstrate the S…
