The DESI Experiment Part II: Instrument Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift…
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through…
Power law cosmology model comparison with CMB scale information
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +14
Despite the ability of the cosmological concordance model (CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(…
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: cosmological analysis of the DR12 galaxy sample
Shadab Alam, Metin Ata, Stephen Bailey +69
We present cosmological results from the final galaxy clustering data set of the Baryon Oscillation Spectroscopic Survey, part of the Sloan Digital Sky Survey III. Our combined gal…
Jackknife resampling technique on mocks: an alternative method for covariance matrix estimation
S. Escoffier, M. -C. Cousinou, A. Tilquin +6
We present a fast and robust alternative method to compute covariance matrix in case of cosmology studies. Our method is based on the jackknife resampling applied on simulation moc…
Constraints on Cosmology and Gravity from the Dynamics of Voids
Nico Hamaus, Alice Pisani, Paul M. Sutter +4
The Universe is mostly composed of large and relatively empty domains known as cosmic voids, whereas its matter content is predominantly distributed along their boundaries. The rem…
