Fables of reconstruction: controlling bias in the dark energy equation of state
Robert G. Crittenden, Gong-Bo Zhao, Levon Pogosian +2
We develop an efficient, non-parametric Bayesian method for reconstructing the time evolution of the dark energy equation of state w(z) from observational data. Of particular impor…
Halos and Voids in f(R) Gravity
Baojiu Li, Gong-Bo Zhao, Kazuya Koyama
In this paper, we study the distribution of dark matter halos and voids using high resolution simulations in f(R) gravity models with the chameleon mechanism to screen the fifth fo…
Cosmological tests of General Relativity: a principal component analysis
Alireza Hojjati, Gong-Bo Zhao, Levon Pogosian +3
The next generation of weak lensing surveys will trace the evolution of matter perturbations and gravitational potentials from the matter dominated epoch until today. Along with co…
Interacting Dark Energy -- constraints and degeneracies
Timothy Clemson, Kazuya Koyama, Gong-Bo Zhao +2
In standard cosmologies, dark energy interacts only gravitationally with dark matter. There could be a non-gravitational interaction in the dark sector, leading to changes in the e…
Cosmological Measurements with Forthcoming Radio Continuum Surveys
Alvise Raccanelli, Gong-Bo Zhao, David J. Bacon +11
We present forecasts for constraints on cosmological models which can be obtained by forthcoming radio continuum surveys: the wide surveys with the LOw Frequency ARray (LOFAR), Aus…
Cosmic Mach Number: A Sensitive Probe for the Growth of Structure
Yin-Zhe Ma, Jeremiah P. Ostriker, Gong-Bo Zhao
In this Letter, we investigate the potential power of the Cosmic Mach Number (CMN), which is the ratio between the mean velocity and the velocity dispersion of galaxies as a functi…
