Leauthaud, A.; Amon, A.; Singh, S.; Gruen, D.; Lange, J. U.; Huang, S.; Robertson, N. C.; Varga, T. N.; Luo, Y.; Heymans, C.; Hildebrandt, H.; Blake, C.Made available in DSpace on 2022-04-29T08:40:02Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-01; SLAC National Accelerator Laboratory; Lensing without borders is a cross-survey collaboration created to assess the consistency of galaxy-galaxy lensing signals (Δς) across different data sets and to carry out end-to-end tests of systematic errors. We perform a blind comparison of the amplitude of Δς us...
Dark Energy Survey year 1 results: Cosmological constraints from galaxy cluster...
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 ...

Sobreira, F. [UNESP]; De Simoni, F.; Rosenfeld, R. [UNESP]; Da Costa, L. A.N.; Maia, M. A.G.; Makler, M.Made available in DSpace on 2022-04-29T02:16:56Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-11-04; We study forecasts for the accuracy of the determination of cosmological parameters from future large-scale photometric surveys obtained using the full shape of the 2-point galaxy angular correlation function. The effects of linear redshift-space distortion, photometric redshift Gaussian errors, galaxy ...
