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...

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 ...
The des view of the Eridanus supervoid and the CMB cold spot
Kovács, A.; Jeffrey, N.; Gatti, M.; Chang, C.; Whiteway, L.; Hamaus, N.; Lahav, O.; Pollina, G.; Bacon, D.; Kacprzak, T.; Mawdsley, B.; Nadathur, S.Made available in DSpace on 2022-04-29T08:41:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-02-01; The Cold Spot is a puzzling large-scale feature in the Cosmic Microwave Background temperature maps and its origin has been subject to active debate. As an important foreground structure at low redshift, the Eridanus supervoid was recently detected, but it was subsequently determined that, assuming the ...

Abbott, T. M.C.; Abdalla, F. B.; Alarcon, A.; Aleksić, J.; Allam, S.; Allen, S.; Amara, A.; Annis, J.; Asorey, J.; Avila, S.; Bacon, D.; Balbinot, E.Made available in DSpace on 2022-04-29T08:27:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-08-15; We present cosmological results from a combined analysis of galaxy clustering and weak gravitational lensing, using 1321 deg2 of griz imaging data from the first year of the Dark Energy Survey (DES Y1). We combine three two-point functions: (i) the cosmic shear correlation function of 26 million source ...
Dark Energy Survey Year 3 results: Curved-sky weak lensing mass map reconstruction
Jeffrey, N.; Gatti, M.; Chang, C.; Whiteway, L.; Demirbozan, U.; Kovacs, A.; Pollina, G.; Bacon, D.; Hamaus, N.; Kacprzak, T.; Lahav, O.; Lanusse, F.Made available in DSpace on 2022-04-29T08:30:11Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-08-01; We present reconstructed convergence maps, mass maps, from the Dark Energy Survey (DES) third year (Y3) weak gravitational lensing data set. The mass maps are weighted projections of the density field (primarily dark matter) in the foreground of the observed galaxies. We use four reconstruction methods,...
