We use ROSAT All Sky Survey (RASS) broadband X-ray images and the optical clusters identified from SDSS DR7 to estimate the X-ray luminosities around candidate cluste…
An analytical model of the large neutral regions during the late stage of reionization
Yidong Xu, Bin Yue, Meng Su +2
In this paper we investigate the nature and distribution of large neutral regions during the late epoch of reionization. In the "bubble model" of reionization, the mass distributio…

With the largest spectroscopic galaxy survey volume drawn from the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS), we can extract cosmological constraints from the measure…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Baryon Acoustic Oscillations in the Data Release 10 and 11 galaxy samples
Lauren Anderson, Eric Aubourg, Stephen Bailey +62
We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation…
Constraints on a decomposed dark fluid with constant adiabatic sound speed by jointing the geometry test and growth rate after Planck data
Weiqiang Yang, Lixin Xu, Yuting Wang +1
In this paper, a unified dark fluid with constant adiabatic sound speed is decomposed into cold dark matter interacting with vacuum energy. Based on Markov chain Monte Carlo method…
Constraints on a CDM model from strong gravitational lensing and updated Hubble parameter measurements
Yun Chen, Chao-Qiang Geng, Shuo Cao +2
We constrain the scalar field dark energy model with an inverse power-law potential, i.e., (), from a set of recent cosmological observations by compiling…
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…
Using pulsar timing arrays and the quantum normalization condition to constrain relic gravitational waves
Ming-Lei Tong, Yang Zhang, Wen Zhao +3
In the non-standard model of relic gravitational waves (RGWs) generated in the early universe, the theoretical spectrum of is mainly described by an amplitude and a spectral in…
An estimation of local bulk flow with the maximum-likelihood method
Yin-Zhe Ma, Jun Pan
A maximum-likelihood method, tested as an unbiased estimator from numerical simulations, is used to estimate cosmic bulk flow from peculiar velocity surveys. The likelihood functio…
Supermassive black holes with high accretion rates in active galactic nuclei: I. First results from a new reverberation mapping campaign
P. Du, C. Hu, K. -X. Lu +7
We report first results from a large project to measure black hole (BH) mass in high accretion rate active galactic nuclei (AGNs). Such objects may be different from other AGNs in…
Effects of plasma on gravitational lensing

We present a new technique to measure neutrino masses using their flow field relative to dark matter. Present day streaming motions of neutrinos relative to dark matter and baryons…
Discovery of eight lensing clusters of galaxies
S. M. Liang, Z. L. Wen, J. L. Han +1
Clusters of galaxies have a huge mass which can act as gravitational lenses. Galaxies behind clusters can be distorted to form arcs in images by the lenses. Herein a search was don…
