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…

Polarization-shape alignment of IllustrisTNG star-forming galaxies

Rui Zhou, Liang Dai, Junwu Huang +2

In star-forming disk galaxies, the radio continuum emission (-GHz) powered by star formation has an integrated polarization direction imperfectly aligned with the apparent…

Periodic Cosmic String Formation and Dynamics

Michael A. Fedderke, Junwu Huang, Nils Siemonsen

We study string formation and dynamics in a scalar field theory with a global symmetry. If a scalar field is initially displaced from the minimum of a wine-bottle potent…

Constraints on axions from patchy screening of the cosmic microwave background

Samuel Goldstein, Fiona McCarthy, Cristina Mondino +3

The resonant conversion of cosmic microwave background (CMB) photons into axions within large-scale structure induces an anisotropic spectral distortion in CMB temperature maps. Ap…

Dark photon limits from patchy dark screening of the cosmic microwave background

Fiona McCarthy, Dalila Pirvu, J. Colin Hill +3

Dark photons that kinetically mix with the Standard Model photon give rise to new spectral anisotropies (patchy dark screening) in the cosmic microwave background (CMB) due to conv…

Axion-Induced Patchy Screening of the Cosmic Microwave Background

Cristina Mondino, Dalila Pîrvu, Junwu Huang +1

Cosmic Microwave Background (CMB) photons can undergo resonant conversion into axions in the presence of magnetized plasma distributed inside non-linear large-scale structure (LSS)…

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…
