Efficient Mass Estimate at the Core of Strong Lensing Galaxy Clusters Using the Einstein Radius
J. D. Remolina González, K. Sharon, B. Reed +7
In the era of large surveys, yielding thousands of galaxy clusters, efficient mass proxies at all scales are necessary in order to fully utilize clusters as cosmological probes. At…
The Outer Rim Simulation: A Path to Many-Core Supercomputers
Katrin Heitmann, Hal Finkel, Adrian Pope +10
We describe the Outer Rim cosmological simulation, one of the largest high-resolution N-body simulations performed to date, aimed at promoting science to be carried out with large-…
A Physical Picture of Bispectrum Baryon Acoustic Oscillations in the Interferometric Basis
Hillary L. Child, Zachary Slepian, Masahiro Takada
We present a picture of the matter bispectrum in a novel "interferometric" basis designed to highlight interference of the baryon acoustic oscillations (BAO) in the power spectra c…
The importance of secondary halos for strong lensing in massive galaxy clusters across redshift
Nan Li, Michael D. Gladders, Katrin Heitmann +6
Cosmological cluster-scale strong gravitational lensing probes the mass distribution of the dense cores of massive dark matter halos and the structures along the line of sight from…
Bispectrum as Baryon Acoustic Oscillation Interferometer
Hillary L. Child, Masahiro Takada, Takahiro Nishimichi +4
The galaxy bispectrum, measuring excess clustering of galaxy triplets, offers a probe of dark energy via baryon acoustic oscillations (BAOs). However up to now it has been severely…
Halo Profiles and the Concentration-Mass Relation for a ΛCDM Universe
Hillary L. Child, Salman Habib, Katrin Heitmann +4
Profiles of dark matter-dominated halos at the group and cluster scales play an important role in modern cosmology. Using results from two very large cosmological -body simulati…
Preheating with Non-Minimal Kinetic Terms
Hillary L. Child, John T. Giblin, Raquel H. Ribeiro +1
We present the first 3+1-dimensional numerical simulations of scalar fields with non-minimal kinetic terms. As an example, we examine the existence and stability of preheating in t…
Gravitational Radiation from First-Order Phase Transitions
Hillary L. Child, John T. Giblin
It is believed that first-order phase transitions at or around the GUT scale will produce high-frequency gravitational radiation. This radiation is a consequence of the collisions…
