Dark Energy Survey Year 1 Results: A Precise H-0 Estimate from DES Y1, BAO, and D/H Data

Juan Andrei Villarroel Fernandez, Eduardo Sanchez, Craig Matthew Smith, Aaron James Rossini, Augusto Martins Lima, Jonathan Andrew Blazek

We combine Dark Energy Survey Year 1 clustering and weak lensing data with baryon acoustic oscillations and Big Bang nucleosynthesis experiments to constrain the Hubble constant. Assuming a flat Lambda CDM model with minimal neutrino mass (Sigma m(v), = 0. ...

DES Y1 Results: validating cosmological parameter estimation using simulated Dark Energy Surveys

Eduardo Sanchez, Mingkui Wang, Craig Matthew Smith, Augusto Martins Lima, Jonathan Andrew Blazek

We use mock galaxy survey simulations designed to resemble the Dark Energy Survey Year 1 (DES Y1) data to validate and inform cosmological parameter estimation. When similar analysis tools are applied to both simulations and real survey data, they provide ...

Cosmological constraints from the convergence 1-point probability distribution

Jonathan Andrew Blazek

We examine the cosmological information available from the 1-point probability density function (PDF) of the weak-lensing convergence field, utilizing fast L-PICOLA simulations and a Fisher analysis. We find competitive constraints in the Omega(m)-sigma(8) ...
