Non-Gaussianity from Step Features in the Inflationary Potential
Peter Adshead, Cora Dvorkin, Wayne Hu +1
We provide analytic solutions for the power spectrum and bispectrum of curvature fluctuations produced by a step feature in the inflaton potential, valid in the limit that the step…
Probing Cosmology with Weak Lensing Minkowski Functionals
Jan M. Kratochvil, Eugene A. Lim, Sheng Wang +3
In this paper, we show that Minkowski Functionals (MFs) of weak gravitational lensing (WL) convergence maps contain significant non-Gaussian, cosmology-dependent information. To do…
Cosmological Information in Weak Lensing Peaks
Xiuyuan Yang, Jan M. Kratochvil, Sheng Wang +3
Recent studies have shown that the number counts of convergence peaks N(kappa) in weak lensing (WL) maps, expected from large forthcoming surveys, can be a useful probe of cosmolog…
Can we detect Hot or Cold spots in the CMB with Minkowski Functionals?
Eugene A. Lim, Dennis Simon
In this paper, we investigate the utility of Minkowski Functionals as a probe of cold/hot disk-like structures in the CMB. In order to construct an accurate estimator, we resolve a…
Modified Gravity Makes Galaxies Brighter
Anne-Christine Davis, Eugene A. Lim, Jeremy Sakstein +1
We investigate the effect of modifed gravity with screening mechanisms, such as the chameleon or symmetron models, upon the structure of main sequence stars. We find that unscreene…
