Dark Energy Survey Year 6 Results: Redshift Calibration of the MagLim++ Lens Sample
G. Giannini, A. Alarcon, W. d'Assignies +85
In this work, we derive and calibrate the redshift distribution of the MagLim++ lens galaxy sample used in the Dark Energy Survey Year 6 (DES Y6) 3x2pt cosmology analysis. The 3x2p…

Dark Energy Survey Year 3 results: CDM cosmology from simulation-based inference with persistent homology on the sphere
J. Prat, M. Gatti, C. Doux +94
We present cosmological constraints from Dark Energy Survey Year 3 (DES Y3) weak lensing data using persistent homology, a topological data analysis technique that tracks how featu…

Homology and Cohomology of Finite Spaces
Carmona Sánchez, V., Maestro Pérez +5
We provide base change theorems, projection formulae and Verdier duality for both cohomology and homology in the context of finite topological spaces
