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 ...

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 ...
Cosmological Constraints from Multiple Probes in the Dark Energy Survey

Muir, J.; Baxter, E.; Miranda, V.; Doux, C.; Ferté, A.; Leonard, C. D.; Huterer, D.; Jain, B.; Lemos, P.; Raveri, M.; Nadathur, S.; Campos, A. [UNESP]Made available in DSpace on 2022-04-29T08:29:09Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-21; We analyze Dark Energy Survey (DES) data to constrain a cosmological model where a subset of parameters - focusing on ωm - are split into versions associated with structure growth (e.g., ωmgrow) and expansion history (e.g., ωmgeo). Once the parameters have been specified for the ΛCDM cosmological model,...

No. of bitstreams: 0 Previous issue date: 2021-06-15; We study a phenomenological class of models where dark matter converts to dark radiation in the low redshift epoch. This class of models, dubbed DMDR, characterizes the evolution of comoving dark-matter density with two extra parameters, and may be able to help alleviate the observed discrepancies betwe...
