The year-scale X-ray variations in the core of M87
Yu-Lin Cheng, Fei Xiang, Heng Yu +5
The analysis of light variation of M87 can help us understand the disc evolution. In the past decade, M87 has experienced several short-term light variabilities related to flares.…
Disk evolution of the M87's nucleus observed in 2008
Fei Xiang, Cheng Cheng
We report the discovery of year-scale X-ray variation in the nuclear region of the M87 by reanalyzing the 8 Chandra observations from 2007 to 2008. The X-ray spectra are fitted and…
Deprojected analysis of Abell 1835 observed with Chandra and compared with XMM-Newton
Chengkui Li, Shumei Jia, Yong Chen +3
Using a deprojection technique, we study the X-ray properties of the galaxy cluster Abell 1835 observed with Chandra, including temperature, abundance, electron density, gas mass f…
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…
Evolution of gaseous disk viscosity driven by supernova explosion in star-forming galaxies at high redshift
Jian-Min Wang, Chang-Shuo Yan, Yan-Rong Li +5
Motivated by Genzel et al.'s observations of high-redshift star-forming galaxies, containing clumpy and turbulent rings or disks, we build a set of equations describing the dynamic…
On the width of cold fronts in clusters of galaxies due to conduction
F. Xiang, E. Churazov, K. Dolag +2
We consider the impact of thermal conduction in clusters of galaxies on the (unmagnetized) interface between a cold gaseous cloud and a hotter gas flowing over the cloud (the so-ca…
