Generalized Slow Roll for Non-Canonical Kinetic Terms
Wayne Hu
We show that the generalized slow-roll approach for calculating the power spectrum where the inflationary slow roll parameters are neither small nor slowly varying can be readily e…
Simultaneous Falsification of LCDM and Quintessence with Massive, Distant Clusters
Michael J. Mortonson, Wayne Hu, Dragan Huterer
Observation of even a single massive cluster, especially at high redshift, can falsify the standard cosmological framework consisting of a cosmological constant and cold dark matte…
Cluster Constraints on f(R) Gravity
Fabian Schmidt, Alexey Vikhlinin, Wayne Hu
Modified gravitational forces in models that seek to explain cosmic acceleration without dark energy typically predict deviations in the abundance of massive dark matter halos. We…
Evidence for horizon-scale power from CMB polarization
Michael J. Mortonson, Wayne Hu
The CMB temperature power spectrum offers ambiguous evidence for the existence of horizon-scale power in the primordial power spectrum due to uncertainties in spatial curvature and…
Acceleration from Modified Gravity: Lessons from Worked Examples
Wayne Hu
I examine how two specific examples of modified gravity explanations of cosmic acceleration help us understand some general problems confronting cosmological tests of gravity: how…
The existence of relativistic stars in f(R) gravity
Amol Upadhye, Wayne Hu
We refute recent claims in the literature that stars with relativistically deep potentials cannot exist in gravity. Numerical examples of stable stars, including relativisti…
