No. of bitstreams: 0 Previous issue date: 2021-11-10; Comet C/2014 UN271 (Bernardinelli-Bernstein), incoming from the Oort cloud, is remarkable in having the brightest (and presumably largest) nucleus of any well-measured comet and having been discovered at the heliocentric distance r h ≈ 29 au, farther than any Oort cloud comet. In this work, we describe ...
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...
