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...

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 ...

Cosmological Constraints from Multiple Probes in the Dark Energy Survey
Abbott, T. M.C.; Alarcon, A.; Allam, S.; Andersen, P.; Andrade-Oliveira, F. [UNESP]; Annis, J.; Asorey, J.; Avila, S.; Bacon, D.; Banik, N.Made available in DSpace on 2022-04-29T08:28:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-05-01; The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Survey has measured 207 spectroscopically confirmed type Ia supernova light curves, the baryon acoustic oscillation feature, w...

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,...; Department of Physics and Astronomy University College London, Gower Street
