Tracking the curved jet in PKS 1502+106
T. An, X. Y. Hong, T. Venturi +2
We carried out a multifrequency and multiepoch study of the highly polarized quasar, PKS 1502+106 at radio frequencies. The analysis is based on an EVN dataset at 5 GHz, archive VL…
The Center of Activity in the CSS Superluminal Source 3C 138
Z. -Q. Shen, L. -L. Shang, H. -B. Cai +7
We present the results from the first quasi-simultaneous multi-frequency (2.3, 5.0, 8.4 and 15 GHz) Very Long Baseline Interferometry (VLBI) observations of a compact steep spectru…
The radio counter-jet of the QSO 3C~48
W. X. Feng, T. An, X. Y. Hong +4
We present multi--frequency radio observational results of the quasar 3C~48. The observations were carried out with the Very Large Array (VLA) at five frequencies of 0.33, 1.5, 4.8…
Correlations among Multi-Wavelength Luminosities of Star-Forming Galaxies
Yu-Qing Lou, Fu-Yan Bian
It has been known for two decades that a tight correlation exists between far-infrared (FIR) and radio (1.4 and 4.8 GHz) global fluxes/luminosities from galaxies, which may be expl…
Structure and evolution of low-mass W UMa type systems -- II. with angular momentum loss
L. Li, Z. Han, F. Zhang
In a preceding paper, using Eggleton's evolution code we have discussed the structure and evolution of low-mass W UMa type contact binaries without angular momentum loss (AML). The…
Early optical afterglow lightcurves of neutron-fed Gamma-ray bursts
Y. Z. Fan, B. Zhang, D. M. Wei
In this paper, within the popular internal shock scenario of GRBs, we calculate the early optical afterglow lightcurves of a neutron-fed GRB fireball for different assumed neutron…
13 Color Photometry of Open Cluster M48
Zhen-Yu Wu, Xu Zhou, Jun Ma +2
This paper presents 13 color CCD intermediate-band spectrophotometry of a field centered on the open cluster M48 (NGC 2548), from 400nm to nearly 1000nm, taken with Beijing-Arizona…
A recent rebuilding of most spirals ?
F. Hammer, H. Flores, X. Z. Zheng +1
Re-examination of the properties of distant galaxies leads to the evidence that most present-day spirals have built up half of their stellar masses during the last 8 Gyr, mostly du…
The iron lines as a tool for magnetic field estimations in non-flat accretion flows
A. F. Zakharov, Z. Ma, Y. Bao
Observations of AGNs and microquasars by ASCA, RXTE, Chandra and XMM-Newton indicate the existence of broad X-ray emission lines of ionized heavy elements in their spectra. Such sp…
Integrating Existing Software Toolkits into VO System
Chenzhou Cui, Yongheng Zhao, Xiaoqian Wang +2
Virtual Observatory (VO) is a collection of interoperating data archives and software tools. Taking advantages of the latest information technologies, it aims to provide a data-int…
Did most present-day spirals form during the last 8 Gyrs? A formation history with violent episodes revealed by panchromatic observations
F. Hammer, H. Flores, D. Elbaz +3
(abridged) Studies of distant galaxies have shown that ellipticals and large spirals were already in place 8 Gyr ago, leading to a very modest recent star formation in intermediate…
Relationship between the gamma-ray burst pulse width and energy due to the Doppler effect of fireballs
Y. -P. Qin, Y. -M. Dong, R. -J. Lu +2
We study in details how the pulse width of gamma-ray bursts is related with energy under the assumption that the sources concerned are in the stage of fireballs. Due to the Doppler…
Generalized Chaplygin gas as a unified scenario of dark matter/energy: observational constraints
Zong-Hong Zhu
Although various cosmological observations congruously suggest that our universe is dominated by two dark components, the cold dark matter without pressure and the dark energy with…
A study of high velocity molecular outflows with an up-to-date sample
Yuefang Wu, Yue Wei, Ming Zhao +4
A statistical study of the properties of molecular outflows is performed based on an up-to-date sample. 391 outflows were identified in published articles or preprints before Febru…
Structures in a class of magnetized scale-free discs
Yue Shen, Xin Liu, Yu-Qing Lou
We construct analytically stationary global configurations for both aligned and logarithmic spiral coplanar magnetohydrodynamic (MHD) perturbations in an axisymmetric background MH…
Quasinormal modes of charged black holes in string theory
Fu-Wen Shu, You-Gen Shen
Both scalar and Dirac quasinormal modes in Garfinkle-Horowitz-Strominger black hole spacetime are studied by using the WKB approximation and the Pöschl-Teller approximation. For sc…
Phantom Cosmology with Non-minimally Coupled Real Scalar Field
Zu-Yao Sun, You-Gen Shen
We find that the expansion of the universe is accelerating by analyzing the recent observation data of type $\textsc{I}a$ supernova(SN-Ia) .It indicates that the equation of state…
MHD tidal waves on a spinning magnetic compact star
Yu-Qing Lou
In an X-ray binary system, the companion star feeds the compact neutron star with plasma materials via accretions. The spinning neutron star is likely covered with a thin "magnetiz…
