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…
NuSTAR and NICER reveal IGR J17591-2342 as a new accreting millisecond X-ray pulsar
A. Sanna, C. Ferrigno, P. S. Ray +21
We report on the discovery by the Nuclear Spectroscopic Telescope Array (NuSTAR) and the Neutron Star Interior Composition Explorer (NICER) of the accreting millisecond X-ray pulsa…
SWIFT J1756.9-2508: spectral and timing properties of its 2018 outburst
A. Sanna, F. Pintore, A. Riggio +8
We discuss the spectral and timing properties of the accreting millisecond X-ray pulsar SWIFT J1756.9-2508 observed by XMM-Newton, NICER and NuSTAR during the X-ray outburst occurr…
XMM-Newton detection of the 2.1 ms coherent pulsations from IGR J17379-3747
A. Sanna, E. Bozzo, A. Papitto +7
We report on the detection of X-ray pulsations at 2.1 ms from the known X-ray burster IGR J17379-3747 using XMM-Newton. The coherent signal shows a clear Doppler modulation from wh…
IGR J17329-2731: The birth of a symbiotic X-ray binary
E. Bozzo, A. Bahramian, C. Ferrigno +10
We report on the results of the multiwavelength campaign carried out after the discovery of the INTEGRAL transient IGR J17329-2731. The optical data collected with the SOAR telesco…
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…
