PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to ESA in May 2013 as a large-class mission for investigating within the framework of the ESA Cosmic Vision program a set of important scientific questions that require high resolution, high sensi...

Comment: 16 pages, 2 figures, small changes to match journal accepted version

Comment: 52 pages, 23 figures. A four page summary of methods and results follows the introduction. Version 2 contains minor clarifications and edits to match the version accepted for publication by JCAP. Version 3 fixes a typo in Eq. 3.10 and a typo in the paragraph af...

We use cosmic microwave background (CMB) data from the 9-year WMAP release to derive constraints on monodromy inflation, which is characterized by a linear inflaton potential with a periodic modulation. We identify two possible periodic modulations that significantly im...

Comment: 31 pages, 17 figures. Revised to match published version. Minor clarifications, conclusions unchanged

Comment: 17 pages, 7 figures. v3: replaced with version published in JCAP (typo fixes, including Figure 1 units)

Comment: 28 pages, 10 figures, accepted to JCAP with minor changes

Weak gravitational lensing alters the apparent separations between observed sources, potentially affecting clustering statistics. We derive a general expression for the lensing deflection which is valid for any three-point statistic, and investigate its effect on the th...

We study collisions between nearly planar domain walls including the effects of small initial nonplanar fluctuations. These perturbations represent the small fluctuations that must exist in a quantum treatment of the problem. In a previous paper, we demonstrated that at...
