Discovery of Red-shifted He-like Iron Absorption Line from Luminous Accreting Neutron Star SMC X-1
Megu Kubota, Hirokazu Odaka, Toru Tamagawa +1
We have analyzed X-ray data of SMC X-1 obtained with \textit{Suzaku}, and discovered a combination of an absorption line and an underlying broadened emission line centered at 6.4 k…
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…
INO: Interplanetary Network of Optical Lattice Clocks
Toshikazu Ebisuzaki, Hidetoshi Katori, Jun'ichiro Makino +3
The new technique of measuring frequency by optical lattice clocks now approaches to the relative precision of . We propose to place such precise clocks in spac…
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…
