High mass and halo resolution from fast low resolution simulations
Biwei Dai, Yu Feng, Uros Seljak +1
Generating mocks for future sky surveys requires large volumes and high resolutions, which is computationally expensive even for fast simulations. In this work we try to develop nu…
Cosmology with galaxy-galaxy lensing on non-perturbative scales: Emulation method and application to BOSS LOWZ
Benjamin D. Wibking, David H. Weinberg, Andrés N. Salcedo +5
We describe our nonlinear emulation (i.e., interpolation) framework that combines the halo occupation distribution (HOD) galaxy bias model with -body simulations of nonlinear st…
Deep+Wide Lensing Surveys will Provide Exquisite Measurements of the Dark Matter Halos of Dwarf Galaxies
Alexie Leauthaud, Sukhdeep Singh, Yifei Luo +5
The advent of new deep+wide photometric lensing surveys will open up the possibility of direct measurements of the dark matter halos of dwarf galaxies. The HSC wide survey will be…
Deep Multi-object Spectroscopy to Enhance Dark Energy Science from LSST
Jeffrey A. Newman, Jonathan Blazek, Nora Elisa Chisari +14
Community access to deep (i ~ 25), highly-multiplexed optical and near-infrared multi-object spectroscopy (MOS) on 8-40m telescopes would greatly improve measurements of cosmologic…
Wide-field Multi-object Spectroscopy to Enhance Dark Energy Science from LSST
Rachel Mandelbaum, Jonathan Blazek, Nora Elisa Chisari +12
LSST will open new vistas for cosmology in the next decade, but it cannot reach its full potential without data from other telescopes. Cosmological constraints can be greatly enhan…
Cosmological constraints from galaxy-lensing cross correlations using BOSS galaxies with SDSS and CMB lensing
Sukhdeep Singh, Rachel Mandelbaum, Uroš Seljak +2
We present cosmological parameter constraints based on a joint modeling of galaxy-lensing cross correlations and galaxy clustering measurements in the SDSS, marginalizing over smal…
