Filtering out large-scale noise for cluster weak-lensing mass estimation
C. Murray, C. Combet, C. Payerne +1
We present a new method for estimating galaxy cluster masses using weak-lensing magnification. The effect of weak-lensing magnification introduces a correlation between the positio…

Multipole analysis of cluster weak lensing shear in The Three Hundred project
Constantin Payerne, Corentin Hanser, Calum Murray +2
Weak gravitational lensing is an important tool to estimate the masses of galaxy clusters, as it allows us to directly access their projected surface mass density along the line-of…

The effects of lensing by local structures on the dipole of radio source counts
Calum Murray
Our peculiar motion in a homogeneous and isotropic universe imprints a dipole in the cosmic microwave background (CMB) temperature field and similarly imprints a dipole in the dist…
