The Clustering of Galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS): measuring growth rate and geometry with anisotropic clustering
Lado Samushia, Beth A. Reid, Martin White +27
We use the observed anisotropic clustering of galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 11 CMASS sample to measure the linear growth rate of struc…
Modeling the nonlinear clustering in modified gravity models I: A fitting formula for matter power spectrum of f(R) gravity
Gong-Bo Zhao
Based on a suite of N-body simulations of the Hu-Sawicki model of f(R) gravity with different sets of model and cosmological parameters, we develop a new fitting formula with a num…
Growth of Cosmic Structure: Probing Dark Energy Beyond Expansion
Dragan Huterer, David Kirkby, Rachel Bean +18
The quantity and quality of cosmic structure observations have greatly accelerated in recent years. Further leaps forward will be facilitated by imminent projects, which will enabl…
Reconstructing primordial power spectrum using Planck and SDSS-III measurements
Xin Wang, Gong-Bo Zhao
We develop an accurate and efficient Bayesian method to reconstruct the primordial power spectrum in a model-independent way, and apply it to the latest cosmic microwave background…
Dark energy imprints on the kinematic Sunyaev-Zel'dovich signal
Yin-Zhe Ma, Gong-Bo Zhao
We investigate the imprint of dark energy on the kinetic Sunyaev-Zel'dovich (kSZ) angular power spectrum on scales of to , and find that the kSZ signal is sensit…
Simulating the quartic Galileon gravity model on adaptively refined meshes
Baojiu Li, Alexandre Barreira, Carlton M. Baugh +4
We develop a numerical algorithm to solve the high-order nonlinear derivative-coupling equation associated with the quartic Galileon model, and implement it in a modified version o…
Principal Component Analysis of Modified Gravity using Weak Lensing and Peculiar Velocity Measurements
Shinsuke Asaba, Chiaki Hikage, Kazuya Koyama +3
We perform a principal component analysis to assess ability of future observations to measure departures from General Relativity in predictions of the Poisson and anisotropy equati…
Systematic simulations of modified gravity: chameleon models
Philippe Brax, Anne-C. Davis, Baojiu Li +2
In this work we systematically study the linear and nonlinear structure formation in chameleon theories of modified gravity, using a generic parameterisation which describes a larg…
Modeling halo mass functions in chameleon f(R) gravity
Lucas Lombriser, Baojiu Li, Kazuya Koyama +1
On cosmological scales, observations of the cluster abundance currently place the strongest constraints on f(R) gravity. These constraints lie in the large-field limit, where the m…
The SDSS-III Baryonic Oscillation Spectroscopic Survey: Constraints on the Integrated Sachs Wolfe effect
Carlos Hernandez-Monteagudo, Ashley Ross, Antonio Cuesta +13
In the context of the study of the Integrated Sachs Wolfe effect (ISW), we construct a template of the projected density distribution up to by using the Luminous Gala…
Exploring Vainshtein mechanism on adaptively refined meshes
Baojiu Li, Gong-Bo Zhao, Kazuya Koyama
There has been a lot of research interest in modified gravity theories which utilise the Vainshtein mechanism to recover standard general relativity in regions with high matter den…
