Inflight Calibration of the Hitomi Soft X-ray Spectrometer (2) Point Spread Function

Yoshitomo Maeda, Toshiki Sato, Takayuki Hayashi +14

We present results of inflight calibration of the point spread function (PSF) of the Soft X-ray Telescope (SXT-S) that focuses X-ray onto the pixel array of the Soft X-ray Spectrom…

Hitomi Observations of the LMC SNR N132D: Highly Redshifted X-ray Emission from Iron Ejecta

Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191

We present Hitomi observations of N132D, a young, X-ray bright, O-rich core-collapse supernova remnant in the Large Magellanic Cloud (LMC). Despite a very short observation of only…

X-ray Measurements of the Particle Acceleration Properties at Inward Shocks in Cassiopeia A

Toshiki Sato, Satoru Katsuda, Mikio Morii +5

We present new evidence that the bright non-thermal X-ray emission features in the interior of the Cassiopeia A supernova remnant (SNR) are caused by inward moving shocks based on…

In-orbit performance of the soft X-ray imaging system aboard Hitomi (ASTRO-H)

H. Nakajima, Y. Maeda, H. Uchida +46

We describe the in-orbit performance of the soft X-ray imaging system consisting of the Soft X-ray Telescope and the Soft X-ray Imager aboard Hitomi. Verification and calibration o…

Freely Expanding Knots of X-ray Emitting Ejecta in Kepler's Supernova Remnant

Toshiki Sato, John P. Hughes

We report measurements of proper motion, radial velocity, and elemental composition for 14 X-ray knots in Kepler's supernova remnant (SNR) using Chandra data. The highest speed kno…

Search for Thermal X-ray Features from the Crab nebula with Hitomi Soft X-ray Spectrometer

Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +192

The Crab nebula originated from a core-collapse supernova (SN) explosion observed in 1054 A.D. When viewed as a supernova remnant (SNR), it has an anomalously low observed ejecta m…

Multi-Year X-ray Variations of Iron-K and Continuum Emissions in the Young Supernova Remnant Cassiopeia A

Toshiki Sato, Yoshitomo Maeda, Aya Bamba +9

We found simultaneous decrease of Fe-K line and 4.2-6 keV continuum of Cassiopeia A with the monitoring data taken by Chandra in 2000-2013. The flux change rates in the whole remna…
