No. of bitstreams: 0 Previous issue date: 2019-06-07; We present constraints on extensions of the minimal cosmological models dominated by dark matter and dark energy, ΛCDM and wCDM, by using a combined analysis of galaxy clustering and weak gravitational lensing from the first-year data of the Dark Energy Survey (DES Y1) in combination with external data....
DES Y1 results: Splitting growth and geometry to test ΛcDM
Muir, J.; Baxter, E.; Miranda, V.; Doux, C.; Ferté, A.; Leonard, C. D.; Huterer, D.; Jain, B.; Lemos, P.; Raveri, M.; Nadathur, S.; Campos, A. [UNESP]Made available in DSpace on 2022-04-29T08:29:09Z (GMT). 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,...

Chen, A.; Huterer, D.; Lee, S.; Ferté, A.; Weaverdyck, N.; Alves, O. [UNESP]; Leonard, C. D.; Maccrann, N.; Raveri, M.; Porredon, A.; Di Valentino, E.Made available in DSpace on 2022-04-29T08:29:42Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-06-15; We study a phenomenological class of models where dark matter converts to dark radiation in the low redshift epoch. This class of models, dubbed DMDR, characterizes the evolution of comoving dark-matter density with two extra parameters, and may be able to help alleviate the observed discrepancies betwe...

Science with e-ASTROGAM (a space mission for MeV-GeV gamma-ray astrophysics)
De Angelis, A.; Tatischeff, V.; Grenier, I. A.; McEnery, J.; Mallamaci, M.; Tavani, M.; Oberlack, U.; Hanlon, L.; Walter, R.; Argan, A.e-ASTROGAM (enhanced ASTROGAM) is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated to the study of the non-thermal Universe in the photon energy range from 0.3 MeV to 3 GeV - the lower energy limit can be pushed to energies as low as 150 keV for the tracker, and to 30 keV for calorimetric detection. The mission is ba...
