LCS: A Learnlet-Based Sparse Framework for Blind Source Separation
V. Bonjean, A. Gkogkou, J. L. Starck +1
Blind source separation (BSS) plays a pivotal role in modern astrophysics by enabling the extraction of scientifically meaningful signals from multi-frequency observations. Traditi…
Foreground removal in HI 21 cm intensity mapping under frequency-dependent beam distortions
Athanasia Gkogkou, Victor Bonjean, Jean-Luc Starck +2
Neutral hydrogen (HI) intensity mapping with single-dish experiments is a powerful approach for probing cosmology in the post-reionization epoch. However, the presence of bright fo…
Challenges of standard halo models in constraining galaxy properties from CIB anisotropies
Athanasia Gkogkou, Guilaine Lagache, Matthieu Béthermin +1
The halo model, combined with halo occupation distribution (HOD) prescriptions, is widely used to interpret cosmic infrared background (CIB) anisotropies and connect star-forming g…
