Constraining Cosmology with High Convergence Regions in Weak Lensing Surveys
Sheng Wang, Zoltán Haiman, Morgan May
We propose to use a simple observable, the fractional area of "hot spots" in weak gravitational lensing mass maps which are detected with high significance, to determine background…
Challenges to the DGP Model from Horizon-Scale Growth and Geometry
Wenjuan Fang, Sheng Wang, Wayne Hu +3
We conduct a Markov Chain Monte Carlo study of the Dvali-Gabadadze-Porrati (DGP) self-accelerating braneworld scenario given the cosmic microwave background (CMB) anisotropy, super…
LSST: from Science Drivers to Reference Design and Anticipated Data Products
Željko Ivezić, Steven M. Kahn, J. Anthony Tyson +310
(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a sin…
Is Modified Gravity Required by Observations? An Empirical Consistency Test of Dark Energy Models
Sheng Wang, Lam Hui, Morgan May +1
We apply the technique of parameter-splitting to existing cosmological data sets, to check for a generic failure of dark energy models. Given a dark energy parameter, such as the e…
High Shear Regions in Weak Lensing Surveys Determine Cosmology
Sheng Wang, Zoltan Haiman, Morgan May +1
We propose to use a simple observable, the fractional area of "hot spots" in weak lensing mass maps which are detected with high significance, to determine background cosmological…
Weighing Neutrinos with Galaxy Cluster Surveys
Sheng Wang, Zoltan Haiman, Wayne Hu +2
Large future galaxy cluster surveys, combined with cosmic microwave background observations, can achieve a high sensitivity to the masses of cosmologically important neutrinos. We…
Constraining the Evolution of Dark Energy with a Combination of Galaxy Cluster Observables
Sheng Wang, Justin Khoury, Zoltan Haiman +1
We show that the abundance and redshift distribution () of galaxy clusters in future high--yield cluster surveys, combined with the spatial power spectrum () of the…
