CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
Eddington-Born-Infeld gravity and the large scale structure of the Universe
Máximo Bañados, Pedro G. Ferreira, Constantinos Skordis
It has been argued that a Universe governed by Eddington-Born-Infeld gravity can be compatible with current cosmological constraints. The extra fields introduced in this theory can…
Extended Limber Approximation
Marilena LoVerde, Niayesh Afshordi
We develop a systematic derivation for the Limber approximation to the angular cross-power spectrum of two random fields, as a series expansion in 1/(\ell+1/2). This extended Limbe…
Can the Copernican principle be tested by cosmic neutrino background?
Junji Jia, Hongbao Zhang
The Copernican principle, stating that we do not occupy any special place in our universe, is usually taken for granted in modern cosmology. However recent observational data of su…
Pseudoscalar perturbations and polarization of the cosmic microwave background
Maxim Pospelov, Adam Ritz, Constantinos Skordis
We show that models of new particle physics containing massless pseudoscalar fields super-weakly coupled to photons can be very efficiently probed with CMB polarization anisotropie…
Gravitational Aether and the thermodynamic solution to the cosmological constant problem
Niayesh Afshordi
Cosmological constant problem (in its various versions) is arguably the deepest gap in our understanding of theoretical physics, the solution to which may very likely require revis…
