Black hole magnetosphere with small scale flux tubes
Yajie Yuan, Roger D. Blandford, Dan R. Wilkins
There is observational evidence that the X-ray continuum source that creates the broad fluorescent emission lines in some Seyfert Galaxies may be compact and located at a few gravi…
Detection of polarized gamma-ray emission from the Crab nebula with Hitomi Soft Gamma-ray Detector
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrom…
The Athena WFI Science Products Module
David N. Burrows, Steven Allen, Marshall Bautz +15
The Science Products Module (SPM), a US contribution to the Athena Wide Field Imager, is a highly capable secondary CPU that performs special processing on the science data stream.…
The variability of the warm absorber in I Zwicky 1 as seen by XMM-Newton
C. V. Silva, E. Costantini, M. Giustini +4
We present new XMM-Newton observations of the intriguing warm absorber in I Zwicky 1. This luminous and nearby narrow-line Seyfert 1 galaxy shows ionized absorption by two componen…
The 1.5 Ms Observing Campaign on IRAS 13224-3809: X-ray Spectral Analysis I
J. Jiang, M. L. Parker, A. C. Fabian +16
We present a detailed spectral analysis of the recent 1.5\,Ms XMM-Newton observing campaign on the narrow line Seyfert 1 galaxy IRAS~132243809, taken simultaneously with 500\,ks…
Variable blurred reflection in the narrow-line Seyfert 1 galaxy Mrk 493
K. Bonson, L. C. Gallo, D. R. Wilkins +1
We examine a 200 ks XMM-Newton observation of the narrow-line Seyfert 1 galaxy Mrk 493. The active galaxy was half as bright as in a previous 2003 snapshot observation and the curr…
Hitomi X-ray Observation of the Pulsar Wind Nebula G21.50.9
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +194
We present results from the Hitomi X-ray observation of a young composite-type supernova remnant (SNR) G21.50.9, whose emission is dominated by the pulsar wind nebula (PWN) cont…
