A Joint Chandra and XMM-Newton View of Abell 3158: Massive Off-Centre Cool Gas Clump As A Robust Diagnostic of Merger Stage
Yu Wang, Haiguang Xu, Liyi Gu +5
By analysing the Chandra and XMM-Newton archived data of the nearby galaxy cluster Abell 3158, which was reported to possess a relatively regular, relaxed morphology in the X-ray b…
The X-ray Asynchronous Optical Afterglow of GRB 060912A and Tentative Evidence of a 2175-A Host Dust Extinction Feature
J. Deng, W. Zheng, M. Zhai +6
We present optical photometry of the GRB 060912A afterglow obtained with ground-based telescopes, from about 100 sec after the GRB trigger till about 0.3 day later, supplemented wi…

M. Derouich, F. Auchere, J. C. Vial +1
This paper is dedicated to the assessment of the validity of future coronal spectro-polarimetric observations and to prepare their interpretation in terms of the magnetic field vec…
Phase-resolved spectral analysis of 4U 1901+03 during its outburst
Ya-Juan Lei, Wei Chen, Jin-Lu Qu +5
The high mass X-ray binary 4U 1901+03 was reported to have the pulse profile evolving with the X-ray luminosity and energy during its outburst in February-July 2003: the pulse peak…
The energy dependence of the centroid frequency and phase lag of the QPOs in GRS 1915+105
J. L. Qu, F. J. Lu, Y. Lu +3
We present a study of the centroid frequencies and phase lags of the quasi-periodic oscillations (QPOs) as functions of photon energy for GRS 1915+105. It is found that the centroi…
A Search for Infall Evidence in EGOs I: the Northern Sample
Xi Chen, Zhi-Qiang Shen, Jing-jing Li +2
We report the first systematic survey of molecular lines (including HCO+ (1-0) and 12CO, 13CO, C18O (1-0) lines at 3 mm band) towards a new sample of 88 massive young stellar objec…
X-ray Radiation Mechanisms and Beaming Effect of Hot Spots and Knots in Active Galactic Nuclear Jets
Jin Zhang, J. M. Bai, Liang Chen +1
The observed radio-optical-X-ray spectral energy distributions (SEDs) of 22 hot spots and 45 knots in the jets of 35 active galactic nuclei are complied from literature and modeled…
Modelling the WMAP large-angle anomalies as an effect of a local density inhomogeneity
Li-Ping He, Quan Guo
We investigate large-angle scale temperature anisotropy in the Cosmic Microwave Background (CMB) with the Wilkinson Microwave Anisotropy Probe (WMAP) data and model the large-angle…
Unified dark energy and dark matter from a scalar field different from quintessence
Changjun Gao, Martin Kunz, Andrew R Liddle +1
We explore unification of dark matter and dark energy in a theory containing a scalar field of non-Lagrangian type, obtained by direct insertion of a kinetic term into the energy-m…
The emission positions of kHz QPOs and Kerr spacetime influence
C. M. Zhang, Y. C. Wei, H. X. Yin +5
Based the Alfven wave oscillation model (AWOM) and relativistic precession model (RPM) for twin kHz QPOs, we estimate the emission positions of most detected kHz QPOs to be at r=18…
Adiabatic Perturbations in Homologous Conventional Polytropic Core Collapses of a Spherical Star
Yi Cao, Yu-Qing Lou
We perform a non-radial adiabatic perturbation analysis on homologous conventional polytropic stellar core collapses. The core collapse features a polytropic exponent relat…
Variability and stability in blazar jets on time scales of years: Optical polarization monitoring of OJ287 in 2005-2009
C. Villforth, K. Nilsson, J. Heidt +45
(Abridged) OJ287 is a BL Lac object that has shown double-peaked bursts at regular intervals of ~12 yr during the last ~40 yr. We analyse optical photopolarimetric monitoring data…
Simulations on High-z Long Gamma-Ray Burst Rate
Shu-Fu Qin, En-Wei Liang, Rui-Jing Lu +2
Since the launch of Swift satellite, the detections of high-z (z>4) long gamma-ray bursts (LGRBs) have been rapidly growing, even approaching the very early Universe (the record ho…
Leptonic dark matter annihilation in the evolving universe: constraints and implications
Qiang Yuan, Bin Yue, Xiaojun Bi +2
The cosmic electron and positron excesses have been explained as possible dark matter (DM) annihilation products. In this work we investigate the possible effects of such a DM anni…
Microlensing pulsars
S. Dai, R. X. Xu, A. Esamdin
We investigate the possibilities that pulsars act as the lens in gravitational microlensing events towards the galactic bulge or a spiral arm. Our estimation is based on expectant…
Lower bounds of altitudes for pulsar -ray radiation
K. J. Lee, Y. J. Du, H. G. Wang +3
Determining radiation location observationally plays a very important role in testing the pulsar radiation models. One-photon pair production in the strong magnetic field, $γ-e^{+}…
Discovery of a magnetic neutron star in X-ray transient IGR J01583+6713
W. Wang
IGR J01583+6713 is a new transient source discovered by the INTEGRAL/IBIS hard X-ray surveys. Optical observations suggested that it should be a high mass X-ray binary, but its nat…
New dynamo pattern revealed by solar helical magnetic fields
Hongqi Zhang, T. Sakurai, A. Pevtsov +4
Previously unobservable mirror asymmetry of the solar magnetic field -- a key ingredient of the dynamo mechanism which is believed to drive the 11-year activity cycle -- has now be…
