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 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 rest-frame UV-to-optical spectroscopy of APM 08279+5255 - BAL classification and black hole mass estimates
F. G. Saturni, M. Bischetti, E. Piconcelli +9
We present the analysis of the rest-frame optical-to-UV spectrum of APM 08279+5255, a well-known lensed broad absorption line (BAL) quasar at . The spectroscopic data ar…
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…
Yet another UFO in the X-ray spectrum of a high-z lensed QSO
M. Dadina, C. Vignali, M. Cappi +6
Ultra-fast outflows (UFO) appear to be common in local active galactic nuclei (AGN) and may be powerful enough (1\% of L) to effectively quench the sta…
