A plug-and-play approach with fast uncertainty quantification for weak lensing mass mapping
Hubert Leterme, Andreas Tersenov, Jalal Fadili +1
The paper presents PnPMass, a plug‑and‑play algorithm that reconstructs dark‑matter maps from weak‑lensing shear data using a single deep‑learning denoiser combined with gradient d…
Methodological Frontiers in 21-cm Intensity Mapping: the Treatment of Systematics and Foreground Contamination
Marta Spinelli, Matilde Barberi-Squarotti, José Luis Bernal +29
The distribution of neutral hydrogen (HI) in the post-reionization universe traces the cosmic large-scale structure and therefore serves as a powerful cosmological probe. An effici…
argosim: a Python package for radio interferometric simulations
Ezequiel Centofanti, Emma Ayçoberry, Samuel Farrens +4
In this paper, we present argosim, a Python package for simulating radio interferometric observations. The argosim package is modular, lightweight and compatible with all major ope…
Beyond power spectrum to unveil systematics on HI intensity maps
Pauline Gorbatchev, Jean-Luc Starck, Stefano Camera +1
HI intensity mapping is a promising technique to probe large-scale structure, traditionally analyzed via two-point statistics such as the angular power spectrum. This technique has…
Joint multiband deconvolution for Euclid and Vera C. Rubin images
Utsav Akhaury, Pascale Jablonka, Frédéric Courbin +1
With the advent of surveys like Euclid and Vera C. Rubin, astrophysicists will have access to both deep, high-resolution images and multiband images. However, these two types are n…
