Journal ArticleDOI
Black hole magnetosphere with small-scale flux tubes - II. Stability and dynamics
TL;DR: In this paper, the authors consider the possibility that this X-ray source may be powered by small scale magnetic flux tubes attached to the accretion disk near the supermassive black hole and study the dynamics of such flux tubes as they get continuously twisted by the central compact star/black hole.

TL;DR: In this paper, the authors presented the results from the Suzaku X-ray observations of five flat-spectrum radio quasars (FSRQs), namely PKS0208-512, Q0827+243, PKS1127-145,PKS1510-089 and 3C 454.3, which revealed the nature of high-energy emission of luminous blazars in their low-activity states.

TL;DR: In this article, the velocities of gas motions, metallicities and the multi-temperature structure of the gas in the core of the Perseus cluster were measured using the Soft X-ray Spectrometer (SXS) on board Hitomi.
Journal ArticleDOI
Strong Redshift Clustering of Distant Galaxies
TL;DR: In this paper, the authors present initial results from a redshift survey carried out with the Low Resolution Imaging Spectrograph on the 10~m W. M. Keck Telescope of a field 14.6 arc-min$^2$ in solid angle.
Journal Article
Evidence for enhanced MHD turbulence outside sharp-rimmed supernova remnants
TL;DR: In this article, the authors consider the propagation of synchrotron-emitting electrons near the shocks of supernova remnants and show that for the sharpest rims, this mean free path is typically less than one percent of that derived for cosmic rays of similar rigidity in the interstellar medium.
