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…

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…
