CMBPol Mission Concept Study Probing Ination with CMB Polarization
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of ination. We focus on the prospects for using CMB measurements

TASI Lectures on Inflation
This series of lectures gives a pedagogical review of the subject of cosmological inflation. I discuss Friedmann-Robertson-Walker cosmology and the horizon and flatness problems of the standard hot…

Inflation: Flow, fixed points and observables to arbitrary order in slow roll
I generalize the inflationary flow equations of Hoffman and Turner to arbitrary order in slow roll. This makes it possible to study the predictions of slow roll inflation in the full observable…

The Phantom Bounce: A New Proposal for an Oscillating Cosmology
An oscillating universe cycles through a series of expansions and contractions. We propose a model in which phantom energy with a supernegative pressure (p) grows rapidly and dominates the late-time…

Measuring the cosmological bulk flow using the peculiar velocities of supernovae
We study large-scale coherent motion in our universe using the existing Type IA supernovae data. If the recently observed bulk flow is real, then some imprint must be left on supernovae motion. We…

TLDR
It is shown that eternal inflation is marginally consistent with the refined de Sitter swampland conjecture, and if the refined conjecture is correct, the existence of a landscape-based "multiverse" inString theory is not incompatible with a self-consistent ultraviolet completion, with significant consequences for model building in string theory.

Inflation model constraints from the Wilkinson Microwave Anisotropy Probe three-year data
We extract parameters relevant for distinguishing among single-field inflation models from the Wilkinson Microwave Anisotropy Probe (WMAP) three-year data set, and also from WMAP in combination with…

The zoo plot meets the swampland: mutual (in)consistency of single-field inflation, string conjectures, and cosmological data
We consider single-field inflation in light of string-motivated "swampland" conjectures suggesting that effective scalar field theories with a consistent UV completion must have field excursion…

Horizon crossing and inflation with large η
I examine the standard formalism of calculating curvature perturbations in inflation at horizon crossing, and derive a general relation which must be satisfied for the horizon-crossing formalism to…
