Hubble Space Telescope observations from December 11 2015 detected the expected fifth counter image of SN Refsdal at . In this letter, we compare the time delay predictio…
Dark Energy Survey Year 1 Results: Constraints on Extended Cosmological Models from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, F. B. Abdalla +112
We present constraints on extensions of the minimal cosmological models dominated by dark matter and dark energy, CDM and CDM, by using a combined analysis of galaxy cluster…
Galaxy Clustering in Harmonic Space from the Dark Energy Survey Year 1 Data: Compatibility with Real-Space Results
F. Andrade-Oliveira, H. Camacho, L. Faga +70
We perform an analysis in harmonic space of the Dark Energy Survey Year 1 Data (DES-Y1) galaxy clustering data using products obtained for the real-space analysis. We test our pipe…
DES Y1 results: Splitting growth and geometry to test CDM
J. Muir, E. Baxter, V. Miranda +100
We analyze Dark Energy Survey (DES) data to constrain a cosmological model where a subset of parameters -- focusing on -- are split into versions associated with structure g…
Simulations of the WFIRST Supernova Survey and Forecasts of Cosmological Constraints
