Yu, Zhefu; Martini, Paul; Penton, A.; Davis, T. M.; Malik, U.; Lidman, C.; Tucker, B. E.; Sharp, R.; Kochanek, C. S.; Peterson, B. 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...

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,...

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...
