Cosmic Expansion in Extended Quasidilaton Massive Gravity
Tina Kahniashvili, Arjun Kar, George Lavrelashvili +3
Quasidilaton massive gravity offers a physically well-defined gravitational theory with non-zero graviton mass. We present the full set of dynamical equations governing the expansi…
Cosmological implications of baryon acoustic oscillation (BAO) measurements
Éric Aubourg, Stephen Bailey, Julian E. Bautista +90
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave backgr…
The Clustering of the SDSS DR7 Main Galaxy Sample I: A 4 per cent Distance Measure at z=0.15
Ashley J. Ross, Lado Samushia, Cullan Howlett +3
We create a sample of spectroscopically identified galaxies with from the Sloan Digital Sky Survey (SDSS) Data Release 7, covering 6813 deg. Galaxies are chosen to sa…
The Clustering of the SDSS Main Galaxy Sample II: Mock galaxy catalogues and a measurement of the growth of structure from Redshift Space Distortions at
Cullan Howlett, Ashley J. Ross, Lado Samushia +2
We measure Redshift-Space Distortions (RSD) in the two-point correlation function of a sample of spectroscopically identified galaxies with , an epoch where there…
Tests of redshift-space distortions models in configuration space for the analysis of the BOSS final data release
Martin White, Beth Reid, Chia-Hsun Chuang +4
Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure, which depends both on th…
Primordial Magnetic Helicity Constraints from WMAP Nine-Year Data
Tina Kahniashvili, Yurii Maravin, George Lavrelashvili +1
If a primordial magnetic field in the universe has non-zero helicity, the violation of parity symmetry results in non-zero correlations between cosmic microwave background temperat…
Growth Rate in the Dynamical Dark Energy Models
Olga Avsajanishvili, Natalia A. Arkhipova, Lado Samushia +1
Dark Energy models with slowly-rolling cosmological scalar field provide a popular alternative to the standard, time-independent cosmological constant model. We study simultaneous…
Nonhelical inverse transfer of a decaying turbulent magnetic field
Axel Brandenburg, Tina Kahniashvili, Alexander G. Tevzadze
In the presence of magnetic helicity, inverse transfer from small to large scales is well known in magnetohydrodynamic (MHD) turbulence and has applications in astrophysics, cosmol…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: mock galaxy catalogues for the low-redshift sample
Marc Manera, Lado Samushia, Rita Tojeiro +7
We present one thousand mock galaxy catalogues for the analysis of the Low Redshift Sample (LOWZ, effective redshift z ~ 10.32) of the Baryon Oscillation Spectroscopic Survey Data…
