Inflationary Steps in the Planck Data
V Miranda, Wayne Hu
We extend and improve the modeling and analysis of large-amplitude, sharp inflationary steps for second order corrections required by the precision of the Planck CMB power spectrum…
Novel Probes of Gravity and Dark Energy
Bhuvnesh Jain, Austin Joyce, Rodger Thompson +29
The discovery of cosmic acceleration has stimulated theorists to consider dark energy or modifications to Einstein's General Relativity as possible explanations. The last decade ha…
CDM: Neutrinos help reconcile Planck with the Local Universe
Mark Wyman, Douglas H. Rudd, R. Ali Vanderveld +1
Current measurements of the low and high redshift Universe are in tension if we restrict ourselves to the standard six parameter model of flat CDM. This tension has two parts. F…
The abundance of voids and the excursion set formalism
Elise Jennings, Yin Li, Wayne Hu
We present measurements of the number density of voids in the dark matter distribution from a series of N-body simulations of a ΛCDM cosmology. We define voids as spherical regions…
Bispectrum in Single-Field Inflation Beyond Slow-Roll
Peter Adshead, Wayne Hu, V Miranda
We develop an integral form for the bispectrum in general single-field inflation whose domain of validity includes models of inflation where the background evolution is not constra…
Power Spectrum Super-Sample Covariance
Masahiro Takada, Wayne Hu
We provide a simple, unified approach to describing the impact of super-sample covariance, or beat coupling, on power spectrum estimation in a finite-volume survey. For a wide rang…
