Statistical studies of optically dark gamma-ray bursts in the Swift era

W. Zheng, J. Deng, J. Wang

We compare the properties of optically dark GRBs, defined by the optical-to-X-ray spectral index beta_OX<0.5, and normal ones discovered by the Swift satellite before the year 2008…

Investigating the Disk-Corona Relation in a Blue AGN Sample

Jie-Ying Liu, B. F. Liu

We compile a blue AGN sample from SDSS and investigate the ratio of hard X-ray to bolometric luminosity in dependence on Eddington ratio and black hole mass. Our sample comprises 2…

Origin of the X-rays and Possible GeV-TeV Emission from the Western Hot Spot Of Pictor A

Jin Zhang, J. M. Bai, Liang Chen +1

Pictor A is a nearby Fanaroff-Riley class II (FR II) radio galaxy with a bright hot spot, the western hot spot. Observation of high polarization in the optical emission of the hot…

A Chandra Study of Temperature Substructures in Intermediate-Redshift Galaxy Clusters

Liyi Gu, Haiguang Xu, Junhua Gu +6

By analyzing the gas temperature maps created from the Chandra archive data, we reveal the prevailing existence of temperature substructures on ~100 kpc scales in the central regio…

Rise and fall of the X-ray flash 080330: an off-axis jet?

C. Guidorzi, C. Clemens, S. Kobayashi +31

X-ray flashes (XRFs) are a class of gamma-ray bursts (GRBs) with the peak energy of the time-integrated spectrum, Ep, below 30 keV, whereas classical GRBs have Ep of a few hundreds…

A Synchrotron Self-Compton Scenario for the Very High Energy Gamma-ray Emission of the Intermediate BL Lacertae object W Comae

Jin Zhang

W Comae has significant variability in multi-wavelengthes, from the radio to the gamma-ray bands. A bright outburst in the optical and X-ray bands was observed in 1998, and most re…
