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…
Simulations of the Sunyaev-Zeldovich Effect from Quasars
Suchetana Chatterjee, Tiziana Di Matteo, Arthur Kosowsky +1
Quasar feedback has most likely a substantial but only partially understood impact on the formation of structure in the universe. A potential direct probe of this feedback mechanis…
Detectability of Gravitational Waves from Phase Transitions
Tina Kahniashvili, Arthur Kosowsky, Grigol Gogoberidze +1
Gravitational waves potentially represent our only direct probe of the universe when it was less than one second old. In particular, first-order phase transitions in the early univ…
Faraday Rotation Limits on a Primordial Magnetic Field from WMAP Five-Year Data
Tina Kahniashvili, Yurii Maravin, Arthur Kosowsky
A primordial magnetic field in the early universe will cause Faraday rotation of the linear polarization of the cosmic microwave background generated via Compton scattering at the…
Systematic Errors in Sunyaev-Zeldovich Surveys of Galaxy Cluster Velocities
Suman Bhattacharya, Arthur Kosowsky
Galaxy cluster surveys compiled via the Sunyaev-Zeldovich Effect have the potential to place strong constraints on cosmology, and in particular the nature of dark energy. Here we c…
