Euclid preparation. First investigation of the impact of cross-contamination on spectroscopic redshift measurements with pixel-level simulations
Euclid Collaboration, F. Passalacqua, S. Anselmi +299
We present a study on simulated data focused on understanding the performance of the spectroscopic redshift measurements with the Near-Infrared Spectrometer and Photometer (NISP) i…

Weak Lensing with the SKAO: Radio Shear Measurement
Priyamvad Tripathi, Marzia Rivi, Simon Prunet +2
Cosmic shear measurements have traditionally been dominated by optical surveys, which offer higher resolution, better sensitivity, higher galaxy number density, and wider area cove…

Diffusion models for polarimetric reconstruction of circumstellar environments
Quentin Villegas, Laurence Denneulin, Simon Prunet +5
In this paper, we propose an approach combining diffusion models and inverse problems for the reconstruction of circumstellar disk images. Our method builds upon the Rhapsodie fram…
