The Impact of the Fiducial Cosmology Assumption on BAO Cosmological Parameter Inference
Paul Carter, Florian Beutler, Will J. Percival +3
Standard analysis pipelines for measurements of Baryon Acoustic Oscillations (BAO) in galaxy surveys make use of a fiducial cosmological model to guide the data compression require…
Beyond BAO: improving cosmological constraints from BOSS with measurement of the void-galaxy cross-correlation
Seshadri Nadathur, Paul M. Carter, Will J. Percival +2
We present a measurement of the anisotropic void-galaxy cross-correlation function in the CMASS galaxy sample of the BOSS DR12 data release. We perform a joint fit to the data for…
A Zeldovich reconstruction method for measuring redshift space distortions using cosmic voids
Seshadri Nadathur, Paul Carter, Will Percival
Redshift space distortions (RSD) in the void-galaxy correlation provide information on the linear growth rate of structure in low density environments. Accurate modelling of…
Low Redshift Baryon Acoustic Oscillation Measurement from the Reconstructed 6-degree Field Galaxy Survey
Paul Carter, Florian Beutler, Will J. Percival +3
Low redshift measurements of Baryon Acoustic Oscillations (BAO) test the late time evolution of the Universe and are a vital probe of Dark Energy. Over the past decade both the 6-d…
Power spectrum multipoles on the curved sky: an application to the 6-degree Field Galaxy Survey
Chris Blake, Paul Carter, Jun Koda
The peculiar velocities of galaxies cause their redshift-space clustering to depend on the angle to the line-of-sight, providing a key test of gravitational physics on cosmological…
Consistency of the growth rate in different environments with the 6dF Galaxy Survey: measurement of the void-galaxy and galaxy-galaxy correlation functions
Ixandra Achitouv, Chris Blake, Paul Carter +2
We present a new test of gravitational physics by comparing the growth rate of cosmic structure measured around voids with that measured around galaxies in the same large-scale str…
