Abbott, T. M.C.; Aguena, M.; Allam, S.; Amon, A.; Andrade-Oliveira, F. [UNESP]; Asorey, J.; Avila, S.; Bernstein, G. M.; Bertin, E.; Brandao-Souza, A.Made available in DSpace on 2022-04-29T08:40:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-02-15; We present angular diameter measurements obtained by measuring the position of baryon acoustic oscillations (BAO) in an optimized sample of galaxies from the first three years of Dark Energy Survey data (DES Y3). The sample consists of 7 million galaxies distributed over a footprint of 4100 deg2 with 0....
Dark energy survey year 3 results: Cosmology with peaks using an emulator approach
Zürcher, D.; Fluri, J.; Sgier, R.; Kacprzak, T.; Gatti, M.; Doux, C.; Whiteway, L.; Réfrégier, A.; Chang, C.; Jeffrey, N.; Jain, B.; Lemos, P.Made available in DSpace on 2022-04-29T08:40:07Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-04-01; We constrain the matter density ωm and the amplitude of density fluctuations σ8 within the ΛCDM cosmological model with shear peak statistics and angular convergence power spectra using mass maps constructed from the first three years of data of the Dark Energy Survey (DES Y3). We use tomographic shear ...
The Evolution of AGN Activity in Brightest Cluster Galaxies

B.; Bertin, E.Made available in DSpace on 2022-04-29T08:41:07Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-04-01; We present the results of an analysis of Wide-field Infrared Survey Explorer (WISE) observations of the full 2500 deg2 South Pole Telescope (SPT)-Sunyaev-Zel'dovich cluster sample. We describe a process for identifying active galactic nuclei (AGN) in brightest cluster galaxies (BCGs) based on WISE mid-I...
