Constraining ALPs with linear and circular polarisation measurements of quasar light
Alexandre Payez
We discuss the constraints derived on the mixing of photons with light pseudoscalars using the distributions of good-quality linear and circular polarisation measurements of light…
Large-scale alignments of quasar polarisations: a detailed study of the spinless-particle scenario
A. Payez
The main motivation for our work has been a puzzling observation concerning quasars. No one expected the existence of correlations in the polarisation of visible light coming from…
New constraints on very light pseudoscalars
A. Payez, J. R. Cudell, D. Hutsemékers
Nearly massless axion-like particles are of interest for astrophysical observations, and some constraints on their parameter space do exist in the literature. Here, we propose to p…
New polarimetric constraints on axion-like particles
A. Payez, J. R. Cudell, D. Hutsemékers
We show that the parameter space of axion-like particles can be severly constrained using high-precision measurements of quasar polarisations. Robust limits are derived from the me…
Cornering the axion-like particle explanation of quasar polarisations
A. Payez
In a series of paper, it has been shown that the distribution of polarisation position angles for visible light from quasars is not random in extremely large regions of the sky. As…
Can axion-like particles explain the alignments of the polarisations of light from quasars?
A. Payez, J. R. Cudell, D. Hutsemékers
The standard axion-like particle explanation of the observed large-scale coherent orientations of quasar polarisation vectors is ruled out by the recent measurements of vanishing o…
