Non-Gaussian Structure of B-mode Polarization after Delensing [Replacement]
The B-mode polarization of the cosmic microwave background on large scales has been considered as a probe of gravitational waves from the cosmic inflation. Ongoing and future experiments will, however,...

View ArticleA Constrained-Gradient Method to Control Divergence Errors in Numerical MHD
In numerical magnetohydrodynamics (MHD), a major challenge is maintaining zero magnetic field-divergence (div-B). Constrained transport (CT) schemes can achieve this at high accuracy, but have...
View ArticleLens Masses and Distances from Microlens Parallax and Flux [Replacement]
I present a novel method for measuring lens masses for microlensing events. By combining a measured lens flux with the microlens parallax vector pi_E, it is possible to derive the mass of the lens...
