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...

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...

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...
