Galaxy clustering in harmonic space from the dark energy survey year 1 data: co...
Andrade-Oliveira, F. [UNESP]; Camacho, H. [UNESP]; Faga, L.; Gomes, R.; Rosenfeld, R. [UNESP]; Troja, A. [UNESP]; Alves, O. [UNESP]; Doux, C.Made available in DSpace on 2022-04-29T08:31:46Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-08-01; We perform an analysis in harmonic space of the Dark Energy Survey Year 1 Data (DES-Y1) galaxy clustering photometric data using products obtained for the real-space analysis. We test our pipeline with a suite of lognormal simulations, which are used to validate scale cuts in harmonic space as well as t...

Abbott, T. M.C.; Aguena, M.; Allam, S.; Amon, A.; Andrade-Oliveira, F. [UNESP]; Asorey, J.; Avila, S.; Bernstein, G. M.; Bertin, E.; Brandao-Souza, A.Made available in DSpace on 2022-04-29T08:40:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-02-15; We present angular diameter measurements obtained by measuring the position of baryon acoustic oscillations (BAO) in an optimized sample of galaxies from the first three years of Dark Energy Survey data (DES Y3). The sample consists of 7 million galaxies distributed over a footprint of 4100 deg2 with 0....

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 ...
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...
