The Impact of Light Polarization Effects on Weak Lensing Systematics
Chien-Hao Lin, Brent Tan, Rachel Mandelbaum +1
A fraction of the light observed from edge-on disk galaxies is polarized due to two physical effects: selective extinction by dust grains aligned with the magnetic field, and scatt…

Non-Gaussianity in the Weak Lensing Correlation Function Likelihood -- Implications for Cosmological Parameter Biases
Chien-Hao Lin, Joachim Harnois-Déraps, Tim Eifler +4
We study the significance of non-Gaussianity in the likelihood of weak lensing shear two-point correlation functions, detecting significantly non-zero skewness and kurtosis in one-…
