Impact of Relativistic Effects on the Primordial Non-Gaussianity Signature in the Large-Scale Clustering of Quasars

1 code implementation3 Jul 2020 Mike Shengbo Wang, Florian Beutler, David Bacon

Although one could mitigate the impact on the $f_\textrm{NL}$ signature by adjusting the redshift range or the luminosity threshold of the tracer sample being considered, we suggest that, for future surveys probing large cosmic volumes, relativistic corrections should be forward modelled from the tracer luminosity function including its uncertainties.

Ensemble Slice Sampling: Parallel, black-box and gradient-free inference for correlated & multimodal distributions

2 code implementations14 Feb 2020 Minas Karamanis, Florian Beutler

Slice Sampling has emerged as a powerful Markov Chain Monte Carlo algorithm that adapts to the characteristics of the target distribution with minimal hand-tuning.

Efficient Cosmological Analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure

2 code implementations17 Sep 2019 Thomas Colas, Guido D'Amico, Leonardo Senatore, Pierre Zhang, Florian Beutler

The precision of the cosmological data allows us to accurately approximate the predictions for cosmological observables by Taylor expanding up to a low order the dependence on the cosmological parameters around a reference cosmology.

The Cosmological Analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure

2 code implementations11 Sep 2019 Guido D'Amico, Jérôme Gleyzes, Nickolas Kokron, Dida Markovic, Leonardo Senatore, Pierre Zhang, Florian Beutler, Héctor Gil-Marín

The Effective Field Theory of Large-Scale Structure (EFTofLSS) is a formalism that allows us to predict the clustering of Cosmological Large-Scale Structure in the mildly non-linear regime in an accurate and reliable way.

When combined with supernova Ia data, we find H0 = 67. 3+/-1. 0 km/s/Mpc even for our most general dark energy model, in tension with some direct measurements.

The baryonic acoustic feature is used to obtain model independent constraints cz/H/r_s = 12. 28 +- 0. 82 (6. 7 per-cent accuracy) and D_A/r_s = 9. 05 +- 0. 27 (3. 0 per-cent) with a correlation coefficient of -0. 5, where r_s is the sound horizon scale at the end of the baryonic drag era.
