M.; Aguena, M.Made available in DSpace on 2022-04-29T08:35:22Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-11-01; European Research Council; National Science Foundation; Reverberation mapping is a robust method to measure the masses of supermassive black holes outside of the local Universe. Measurements of the radius-luminosity (R-L) relation using the Mg ii emission line are critical for determining these masses n...
Dark Energy Survey Year 3 Results: Galaxy mock catalogs for BAO analysis
Ferrero, I.; Crocce, M.; Tutusaus, I.; Porredon, A.; Blot, L.; Fosalba, P.; Carnero Rosell, A.; Avila, S.; Izard, A.; Elvin-Poole, J.; Chan, K. C.Made available in DSpace on 2022-04-29T08:37:23Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-12-01; The calibration and validation of scientific analysis in simulations is a fundamental tool to ensure unbiased and robust results in observational cosmology. In particular, mock galaxy catalogs are a crucial resource to achieve these goals in the measurement of baryon acoustic oscillation (BAO) in the cl...

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,...
