Nonlinear Stochastic Biasing of Peaks and Halos: Scale-Dependence, Time-Evolution, and Redshift-Space Distortion from Cosmological N-body Simulations
A. Taruya, H. Magira, Y. P. Jing +1
We quantify the degree of nonlinearity and stochasticity of the clustering of biased objects, using cosmological N-body simulations. Adopting the peaks and the halos as representat…
VLBI, MERLIN and HST observations of the giant radio galaxy 3C236
R. T. Schilizzi, W. W. Tian, J. E. Conway +6
We present VLBI and MERLIN data at 1.66 and 4.99 GHz on the central component coincident with the nucleus of the giant radio galaxy, 3C236. The nuclear radio structure is composed…
Can all breaks in GRB afterglows be explained by jet effects?
D. M. Wei, T. Lu
Whether gamma-ray bursts are highly beamed or not is a very important question, since it has been pointed out that the beaming will lead to a sharp break in the afterglow light cur…
Non-LTE analysis of neutral magnesium in cool stars
G. Zhao, T. Gehren
Calculations of the statistical equilibrium of magnesium in the solar photosphere have shown that NLTE populations hardly affect Mg line formation in the Sun. However, in metal-poo…
Emissive Mechanism on Spectral Variability of Blazars in High Frequencies
Jiancheng Wang, Jirong Mao
The new results of the evolution of the synchrotron peak for Mrk 421 are mostly likely related to the particle acceleration process. In order to account for the above results, we p…
Orbital elements of barium stars formed through a wind accretion scenario
J. H. Liu, B. Zhang, Y. C. Liang +1
Taking the total angular momentum conservation in place of the tangential momentum conservation, and considering the square and higher power terms of orbital eccentricity e, the ch…
The heavy-element abundances of AGB stars and the angular momentum conservation model of wind accretion for barium stars
Y. C. Liang, G. Zhao, B. Zhang
Adpoting new s-process nucleosynthesis scenario and branch s-process path, we calculate the heavy-element abundances and C/O ratio of solar metallicity 3M_sun TP-AGB stars. The evo…
Trapped Disk Oscillations and Stable QPOs in Microquasars
Xue-Bing Wu
The observed quasi-periodic oscillations (QPOs) in low-mass X-ray binaries have been suggested to be probably related to the characteristic oscillation modes in the inner part of a…
The shape of pulsar radio beams
J. L. Han, R. N. Manchester
Using all available multi-component radio pulse profiles for pulsars with medium to long periods and good polarisation data, we have constructed a two-dimensional image of the mean…
Magnetic fields in our Galaxy: How much do we know?
J. L. Han
The large scale magnetic fields of our Galaxy have been mostly revealed by rotation measures (s) of pulsars and extragalactic radio sources. In the disk of our Galaxy, the aver…
The unique rapid variabilities of the iron K line profiles in NGC 4151
Jun-xian Wang, Ting-gui Wang, You-yuan Zhou
We present a detailed analysis of the iron K line variabilities in NGC 4151 by using long ASCA observation data obtained in May 1995. Despite the relatively small amplitude vari…
Gravitational Lensing Statistics as a Probe of Dark Energy
Zong-Hong Zhu
By using the comoving distance, we derive an analytic expression for the optical depth of gravitational lensing, which depends on the redshift to the source and the cosmological mo…
Low and intermediate-mass close binary evolution and the initial - final mass relation
Zhanwen Han, Christopher A. Tout, Peter P. Eggleton
Using Eggleton's stellar evolution code, we carry out 150 runs of Pop I binary evolution calculations, with the initial primary mass between 1 and 8 solar masses the initial mass r…
Two classes of radio flares in the blazar PKS 0420014
J. F. Zhou, X. Y. Hong, D. R. Jiang +1
The two 5GHz VLBI (Very Long Baseline Interferometry) observations (1996 June and 1997 November) presented in this paper, combined with several formerb VLBI observations at 8.4GHz…
Reconstruction of radial temperature profiles of galaxy clusters
Yan-Jie Xue, Xiang-Ping Wu
In this Letter we present the radial temperature profiles of three X-ray clusters (A119, A2255 and A2256) reconstructed from a combination of the X-ray surface brightness measureme…
Radial density and temperature profiles of the intracluster gas constructed jointly from the X-ray surface brightness measurement and the universal density profile
Xiang-Ping Wu, Tzihong Chiueh
In this paper we have made an attempt to derive the radial profiles of density and temperature of intracluster gas based on the two well-established facts at present: the X-ray obs…
Scaling properties of the redshift power spectrum: theoretical models
Y. P. Jing, G. Boerner
We report the results of an analysis of the redshift power spectrum in three typical Cold Dark Matter (CDM) cosmological models, where is the cosine of the angle bet…
Relation between blue/UV continuum shape and the ratio of radio to optical emission for B3-VLA quasars
Minfeng Gu, Xinwu Cao, D. R. Jiang +1
The low frequency radio luminosity is believed to be an indicator of jet power, while the optical/UV emission is probably from accretion discs in the nuclei of steep-spectrum radio…
The relation between extended radio and line emission for radio-loud quasars
Xinwu Cao, D. R. Jiang
We explore the relationship between the extended radio and line emission for a radio-loud quasar sample including both core-dominated and lobe-dominated quasars. A strong correlati…
Cerenkov Line-like Radiation, The Extended and Improved Formulae System
J. H. You, Y. D. Xu, D. B. Liu +2
You & Cheng (1980) argued that, for relativistic electrons moving through a dense gas, the Cerenkov effect will produce peculiar atomic and/or molecular emission lines--Cerenkov li…
