No. of bitstreams: 0 Previous issue date: 2022-01-15; This work and its companion paper, Amon et al. [Phys. Rev. D 105, 023514 (2022)PRVDAQ2470-001010.1103/PhysRevD.105.023514], present cosmic shear measurements and cosmological constraints from over 100 million source galaxies in the Dark Energy Survey (DES) Year 3 data. We constrain the lensing amplitude...
Dark energy survey year 3 results: Cosmology with peaks using an emulator approach
Zürcher, D.; Fluri, J.; Sgier, R.; Kacprzak, T.; Gatti, M.; Doux, C.; Whiteway, L.; Réfrégier, A.; Chang, C.; Jeffrey, N.; Jain, B.; Lemos, P.Made available in DSpace on 2022-04-29T08:40:07Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-04-01; We constrain the matter density ωm and the amplitude of density fluctuations σ8 within the ΛCDM cosmological model with shear peak statistics and angular convergence power spectra using mass maps constructed from the first three years of data of the Dark Energy Survey (DES Y3). We use tomographic shear ...
