Generation of Circular Polarization of the Cosmic Microwave Background
Stephon Alexander, Joseph Ochoa, Arthur Kosowsky
The standard cosmological model, which includes only Compton scattering photon interactions at energy scales near recombination, results in zero primordial circular polarization of…
Local Void vs Dark Energy: Confrontation with WMAP and Type Ia Supernovae
Stephon Alexander, Tirthabir Biswas, Alessio Notari +1
It is now a known fact that if we happen to be living in the middle of a large underdense region, then we will observe an "apparent acceleration", even when any form of dark energy…
Quintessence and variation of the fine structure constant in the CMBR
Greg Huey, Stephon Alexander, Levon Pogosian
We study dependence of the CMB temperature anisotropy spectrum on the value of the fine structure constant and the equation of state of the dark energy component of the total d…
