Zacharegkas, G.; Chang, C.; Prat, J.; Pandey, S.; Ferrero, I.; Blazek, J.; Jain, B.; Crocce, M.; Derose, J.; Palmese, A.; Seitz, S.; Sheldon, E.Made available in DSpace on 2022-04-29T08:37:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-01-01; Galaxy-galaxy lensing is a powerful probe of the connection between galaxies and their host dark matter haloes, which is important both for galaxy evolution and cosmology. We extend the measurement and modelling of the galaxy-galaxy lensing signal in the recent Dark Energy Survey Year 3 cosmology analys...

No. of bitstreams: 0 Previous issue date: 2022-01-01; The DMASS sample is a photometric sample from the DES Year 1 data set designed to replicate the properties of the CMASS sample from BOSS, in support of a joint analysis of DES and BOSS beyond the small overlapping area. In this paper, we present the measurement of galaxy–galaxy lensing using the DMASS s...

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 ...

Rodríguez-Monroy, M.; Weaverdyck, N.; Elvin-Poole, J.; Crocce, M.; Carnero Rosell, A.; Andrade-Oliveira, F. [UNESP]; Avila, S.; Bechtol, K.Made available in DSpace on 2022-04-29T08:40:10Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-04-01; In this work, we present the galaxy clustering measurements of the two DES lens galaxy samples: a magnitude-limited sample optimized for the measurement of cosmological parameters, maglim, and a sample of luminous red galaxies selected with the redmagic algorithm. maglim/redmagic sample contains over 10...

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...
