PublicaciónEstimate of the Accretion Disk Size in the Gravitationally Lensed Quasar HE 0435–1223 Using Microlensing Magnification Statistics
We present a measurement of the accretion disk size of the quadruple lensed quasar HE 0435–1223 from well-sampled 13-year COSMOGRAIL optical light curves. Using...

PublicaciónEuclid preparation. XXVIII. Forecasts for ten different higher-order weak lensing statistics
Recent cosmic shear studies have shown that higher-order statistics (HOS) developed by independent teams now outperform standard two-point estimators in terms...

PublicaciónEuclid preparation. XXXVI. Modelling the weak lensing angular power spectrum
This work considers which higher order modeling effects on the cosmic shear angular power spectra must be taken into account for Euclid. We identified the...
