Unveiling the super-orbital modulation of LS I +61 303 in X-rays
Jian Li, Diego F. Torres, Shu Zhang +5
From the longest monitoring of LS I +61 303 done to date by the Rossi X-ray Timing Explorer (RXTE) we found evidence for the long-sought, years- long modulation in the X-ray emissi…
A magnetar-like event from LS I +61 303 and its nature as a gamma-ray binary
Diego F. Torres, Nanda Rea, Paolo Esposito +3
We report on the Swift-BAT detection of a short burst from the direction of the TeV binary LS I +61 303, resembling those generally labelled as magnetar-like. We show that it is li…
The 2008 outburst of IGR J17473--2721: evidence for a disk corona?
Yu-Peng Chen, Shu Zhang, Diego F. Torres +4
The 2008 outburst of the atoll source IGR J17473--2721 was observed by INTEGRAL, RXTE and Swift. Tens of type-I X-ray bursts were found in this outburst. Joint observations provide…
INTEGRAL observations of the gamma-ray binary 1FGL J1018.6-5856
Jian Li, Diego F. Torres, Yupeng Chen +5
The Fermi-LAT collaboration has recently reported that one of their detected sources, namely, 1FGL J1018.6-5856, is a new gamma-ray binary similar to LS 5039. This has prompted eff…
A Systematic Study on Energy Dependence of Quasi-Periodic Oscillation Frequency in GRS 1915+105
Shu-Ping Yan, Jin-Lu Qu, Guo-Qiang Ding +6
Systematically studying all the RXTE/PCA observations for GRS 1915+105 before November 2010, we have discovered three additional patterns in the relation between Quasi-Periodic Osc…
Star formation in self-gravitating disks in active galactic nuclei. I. Metallicity gradients in broad line regions
J. -M. Wang, J. -Q. Ge, C. Hu +6
It has been suggested that the high metallicity generally observed in active galactic nuclei (AGNs) and quasars originates from ongoing star formation in the self-gravitating part…
