Measuring the Dark Matter Self-Interaction Cross-Section with Deep Compact Clustering for Robust Machine Learning Inference
Ethan Tregidga, David Harvey, Luca Biggio +1
We have developed a machine learning algorithm capable of detecting ``out-of-domain data'' for trustworthy cosmological inference. By using data from two separate suites of cosmolo…
DARKSKIES: A suite of super-sampled zoom-in simulations of galaxy clusters with self-interacting dark matter
David Harvey, Yves Revaz, Matthieu Schaller +3
We present the "DARKSKIES" suite of one hundred, zoom-in hydrodynamic simulations of massive ( galaxy clusters with self-interacting dark matt…
Radiation damage to the Hubble Space Telescope during two Solar cycles, and correction of Charge Transfer Inefficiency using ArCTIc
Richard Massey, Jacob A. Kegerreis, Juan Paolo Lorenzo Gerardo Barrios +8
From 2002 to 2025, the Hubble Space Telescope's Advanced Camera for Surveys has suffered in the harsh radiation environment above the protection of the Earth's atmosphere. We track…
Multiscale Turbulence Synthesis: Validation in 2D Hydrodynamics
Pierre Lesaffre, Jean-Baptiste Durrive, Jean Goossaert +5
Numerical simulations can follow the evolution of fluid motions through the intricacies of developed turbulence. However, they are rather costly to run, especially in 3D. In the pa…
Full non-LTE multi-level radiative transfer I. An atom with three bound infinitely sharp levels
Tristan Lagache, Frédéric Paletou, Malali Sampoorna
The standard nonlocal thermodynamic equilibrium (non-LTE) multi-level radiative transfer problem only takes into account the deviation of the radiation field and atomic populations…
