Cosmological parameter constraints for Horndeski scalar-tensor gravity
Johannes Noller, Andrina Nicola
We present new cosmological parameter constraints for general Horndeski scalar-tensor theories, using CMB, redshift space distortion, matter power spectrum and BAO measurements fro…
Radiative stability and observational constraints on dark energy and modified gravity
Johannes Noller, Andrina Nicola
We investigate the radiative stability of Horndeski scalar-tensor theories with luminally propagating gravitational waves (as extensively discussed in the wake of GW170817) and sho…
Dark Energy Survey Year 1 Results: Joint Analysis of Galaxy Clustering, Galaxy Lensing, and CMB Lensing Two-point Functions
T. M. C. Abbott, F. B. Abdalla, A. Alarcon +164
We perform a joint analysis of the auto and cross-correlations between three cosmic fields: the galaxy density field, the galaxy weak lensing shear field, and the cosmic microwave…
Cosmological lensing ratios with DES Y1, SPT and Planck
J. Prat, E. J. Baxter, T. Shin +131
Correlations between tracers of the matter density field and gravitational lensing are sensitive to the evolution of the matter power spectrum and the expansion rate across cosmic…
Consistency tests in cosmology using relative entropy
Andrina Nicola, Adam Amara, Alexandre Refregier
With the high-precision data from current and upcoming experiments, it becomes increasingly important to perform consistency tests of the standard cosmological model. In this work,…
Forward Modeling of Spectroscopic Galaxy Surveys: Application to SDSS
Martina Fagioli, Julian Riebartsch, Andrina Nicola +6
Galaxy spectra are essential to probe the spatial distribution of galaxies in our Universe. To better interpret current and future spectroscopic galaxy redshift surveys, it is impo…
Dark Energy Survey Year 1 Results: Methodology and Projections for Joint Analysis of Galaxy Clustering, Galaxy Lensing, and CMB Lensing Two-point Functions
E. J. Baxter, Y. Omori, C. Chang +91
Optical imaging surveys measure both the galaxy density and the gravitational lensing-induced shear fields across the sky. Recently, the Dark Energy Survey (DES) collaboration used…
