Signatures of the Baryon Acoustic Oscillations on the Convergence Power Spectrum of Weak lensing by Large Scale Structure
Tong-Jie Zhang, Qiang Yuan, Tian Lan
We employ an analytical approach to investigate the signatures of Baryon Acoustic Oscillations (BAOs) on the convergence power spectrum of weak lensing by large scale structure. It…
Discriminating different scenarios to account for the cosmic excess by synchrotron and inverse Compton radiation
Juan Zhang, Xiao-jun Bi, Jia Liu +4
The excesses of the cosmic positron fraction recently measured by PAMELA and the electron spectra by ATIC, PPB-BETS, Fermi and H.E.S.S. indicate the existence of primary electron a…
Scaling Relation between Sunyaev-Zel'dovich Effect and X-ray Luminosity and Scale-Free Evolution of Cosmic Baryon Field
Qiang Yuan, Hao-Yi Wan, Tong-Jie Zhang +3
It has been revealed recently that, in the scale free range, i.e. from the scale of the onset of nonlinear evolution to the scale of dissipation, the velocity and mass density fiel…
Constraints on the Dark Matter Annihilations by Neutrinos with Substructure Effects Included
Peng-fei Yin, Jia Liu, Qiang Yuan +2
Dark matter (DM) annihilations in the Galaxy may produce high energy neutrinos, which can be detected by the neutrino telescopes, for example IceCube, ANTARES and Super-Kamiokande.…
An Updated Search of Steady TeV Ray Point Sources in Northern Hemisphere Using the Tibet Air Shower Array
Y. Wang, X. J. Bi, S. W. Cui +45
Using the data taken from Tibet II High Density (HD) Array (1997 February-1999 September) and Tibet-III array (1999 November-2005 November), our previous northern sky survey for Te…
Cosmological Constraints from Hubble parameter and SN Ia observations
Hui Lin, Cheng Hao, Xiao Wang +4
In this paper, we use a set of observational data (OHD) to constrain the CDM cosmology. This data set can be derived from the differential ages of the passively evolving…
