Perfectly parallel cosmological simulations using spatial comoving Lagrangian acceleration

Florent Leclercq, Baptiste Faure, Guilhem Lavaux +5

Existing cosmological simulation methods lack a high degree of parallelism due to the long-range nature of the gravitational force, which limits the size of simulations that can be…

A map-based method for eliminating systematic modes from galaxy clustering power spectra with application to BOSS

B. Bahr-Kalus, W. J. Percival, D. J. Bacon +5

We develop a practical methodology to remove modes from a galaxy survey power spectrum that are associated with systematic errors. We apply this to the BOSS CMASS sample, to see if…

Dark matter and halo bispectrum in redshift space: theory and applications

Héctor Gil-Marín, Christian Wagner, Jorge Noreña +2

We present a phenomenological modification of the standard perturbation theory prediction for the bispectrum in redshift space that allows us to extend the model to mildly non-line…

Testing Gravity Using Large-Scale Redshift-Space Distortions

Alvise Raccanelli, Daniele Bertacca, Davide Pietrobon +6

We use Luminous Red Galaxies from the Sloan Digital Sky Survey II to test the cosmological structure growth in two alternatives to the standard LCDM+GR cosmological model. We compa…

Thinking Outside the Box: Effects of Modes Larger than the Survey on Matter Power Spectrum Covariance

Roland de Putter, Christian Wagner, Olga Mena +2

Considering the matter power spectrum covariance matrix, it has recently been found that there is a potentially dominant effect on mildly non-linear scales due to power in modes of…

Simulating Redshift-Space Distortions for Galaxy Pairs with Wide Angular Separation

Alvise Raccanelli, Lado Samushia, Will J. Percival

The analysis of Redshift-Space Distortions (RSD) within galaxy surveys provides constraints on the amplitude of peculiar velocities induced by structure growth, thereby allowing te…
