Nonlocal Gravity and Structure in the Universe
Scott Dodelson, Sohyun Park
The observed acceleration of the Universe can be explained by modifying general relativity. One such attempt is the nonlocal model of Deser and Woodard. Here we fix the background…
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…
Growth of Cosmic Structure: Probing Dark Energy Beyond Expansion
Dragan Huterer, David Kirkby, Rachel Bean +18
The quantity and quality of cosmic structure observations have greatly accelerated in recent years. Further leaps forward will be facilitated by imminent projects, which will enabl…
Neutrino Physics from the Cosmic Microwave Background and Large Scale Structure
K. N. Abazajian, K. Arnold, J. Austermann +74
This is a report on the status and prospects of the quantification of neutrino properties through the cosmological neutrino background for the Cosmic Frontier of the Division of Pa…
Inflation Physics from the Cosmic Microwave Background and Large Scale Structure
K. N. Abazajian, K. Arnold, J. Austermann +91
Fluctuations in the intensity and polarization of the cosmic microwave background (CMB) and the large-scale distribution of matter in the universe each contain clues about the natu…
Imprint of primordial non-Gaussianity on dark matter halo profiles
Azadeh Moradinezhad Dizgah, Scott Dodelson, Antonio Riotto
We study the impact of primordial non-Gaussianity on the density profile of dark matter halos by using the semi-analytical model introduced recently by Dalal {\it et al.} which rel…
