How to augment cosmic shear measurements with radio polarimetry of galaxies?
Liang Dai, Junwu Huang, Weichen Winston Yin +2
The integral polarization of spiral galaxies in the radio band has been proposed as a new tracer of the intrinsic galaxy shape that augments lensing shear measurements. We revisit…
A New Probe of Cosmic Birefringence Using Galaxy Polarization and Shapes
Weichen Winston Yin, Liang Dai, Junwu Huang +2
We propose a novel statistical method to measure cosmic birefringence and demonstrate its power in probing parity violation due to axions. Exploiting an empirical correlation betwe…
Probing cosmic strings by reconstructing polarization rotation of the cosmic microwave background
Weichen Winston Yin, Liang Dai, Simone Ferraro
Cosmic birefringence -- the rotation of the polarization of the cosmic microwave background (CMB) photons as they travel to the Earth -- is a smoking gun for axion-like particles (…
Statistical Properties of Scale-Invariant Helical Magnetic Fields and Applications to Cosmology
Axel Brandenburg, Ruth Durrer, Tina Kahniashvili +2
We investigate the statistical properties of isotropic, stochastic, Gaussian distributed, helical magnetic fields characterized by different shapes of the energy spectra at large l…
