Abbott, T. M.C.; Aguena, M.; Alarcon, A.; Allam, S.; Alves, O. [UNESP]; Amon, A.; Andrade-Oliveira, F. [UNESP]; Annis, J.; Avila, S.; Bacon, D.Made available in DSpace on 2022-04-29T08:39:14Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-15; We present the first cosmology results from large-scale structure using the full 5000 deg2 of imaging data from the Dark Energy Survey (DES) Data Release 1. We perform an analysis of large-scale structure combining three two-point correlation functions (3×2pt): (i) cosmic shear using 100 million source ...
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 ...

Cordero, Juan P.; Harrison, Ian; Rollins, Richard P.; Bernstein, G. M.; Bridle, S. L.; Alarcon, A.; Alves, O. [UNESP]; Amon, A.Made available in DSpace on 2022-04-29T08:40:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-04-01; Cosmological information from weak lensing surveys is maximized by sorting source galaxies into tomographic redshift subsamples. Any uncertainties on these redshift distributions must be correctly propagated into the cosmological results. We present hyperrank, a new method for marginalizing over redshif...
