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…
CMB Temperature Anisotropy from Broken Spatial Isotropy due to an Homogeneous Cosmological Magnetic Field
Tina Kahniashvili, George Lavrelashvili, Bharat Ratra
We derive the cosmic microwave background temperature anisotropy two-point correlation function (including off-diagonal correlations) from broken spatial isotropy due to an arbitra…
Testing Lorentz Invariance Violation with WMAP Five Year Data
Tina Kahniashvili, Ruth Durrer, Yurii Maravin
We consider different renormalizable models of Lorentz invariance violation. We show that the limits on birefringence of the propagation of cosmic microwave background photons from…
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…
