The hard X-ray behavior of Aql X-1 during type-I bursts
Yu-Peng Chen, Shu Zhang, Shuang-Nan Zhang +5
We report the discovery of an anti-correlation between the soft and the hard X-ray lightcurves of the X-ray binary Aql X-1 when bursting. This behavior may indicate that the corona…
The properties of cross-correlation and spectra of the low-mass X-ray binary 4U 1608-52
Ya-Juan Lei, Shu Zhang, Jin-Lu Qu +4
With {\it RXTE} data, we analyzed the cross-correlation function between the soft and hard X-rays of the transient atoll source 4U 1608-52. We found anti-correlations in three outb…
The 2013 multiwavelength campaign on the Narrow-Line Seyfert 1 galaxy 1H 0323+342: a rosetta stone for the jet/disk paradigm
Omar Tibolla, Sarah Kaufmann, Luigi Foschini +11
Narrow-Line Seyfert 1 galaxies have been established as a new class of gamma-ray emitting AGN with relatively low black hole masses, but near-Eddington accretion rates. Other extra…
X-ray bursts as a probe of the corona: the case of XRB 4U 1636-536
Long Ji, Shu Zhang, YuPeng Chen +6
To investigate the possible cooling of the corona by soft X-rays bursts, we have studied 114 bursts embedded in the known X-ray evolution of 4U 1636-536. We have grouped these burs…
Type-I X-ray bursts reveal a fast co-evolving behavior of the corona in an X-ray binary
Yu-Peng Chen, Shu Zhang, Shuang-Nan Zhang +2
The coronae in X-ray binaries (XRBs) still remain poorly understood, although they have been believed for a long time to play a key role in modeling the characteristic outbursts of…
State-Dependent Orbital Modulation of X-rays in CYG X-3
Shan-Shan Weng, Shuang-Nan Zhang, Ming-Yu Ge +2
We analyze all of the available {\it RXTE} observations of Cyg X-3 in order to investigate the connection between the central X-ray source and its surrounding environment. The hard…
