Cosmology with galaxy cluster weak lensing: statistical limits and experimental design
Hao-Yi Wu, David H. Weinberg, Andrés N. Salcedo +1
We forecast constraints on the amplitude of matter clustering sigma_8(z) achievable with the combination of cluster weak lensing and number counts, in current and next-generation w…
Covariance matrices for galaxy cluster weak lensing: from virial regime to uncorrelated large-scale structure
Hao-Yi Wu, David H. Weinberg, Andrés N. Salcedo +2
Next-generation optical imaging surveys will revolutionise the observations of weak gravitational lensing by galaxy clusters and provide stringent constraints on growth of structur…
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…
Cosmology with Stacked Cluster Weak Lensing and Cluster-Galaxy Cross-Correlations
Andrés N. Salcedo, Benjamin D. Wibking, David H. Weinberg +4
Cluster weak lensing is a sensitive probe of cosmology, particularly the amplitude of matter clustering and matter density parameter . The main nuisance parameter in a c…
Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020
Tianshu Wang, Wei Zhu, Shude Mao +83
We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…
Spitzer Observations of OGLE-2015-BLG-1212 Reveal a New Path to Breaking Strong Microlens Degeneracies
V. Bozza, Y. Shvartzvald, A. Udalski +98
Spitzer microlensing parallax observations of OGLE-2015-BLG-1212 decisively breaks a degeneracy between planetary and binary solutions that is somewhat ambiguous when only ground-b…
