" Recent progress in X-ray studies of the Crab Pulsar Wind Nebula "

Koji Mori (University of Miyazaki)

The Crab Nebula in the optical bands shows a filamentary structure of supernova ejecta, while in the X-ray band it is dominated by a synchrotron cloud energized by the central Crab pulsar. In this talk, I will review recent progresses in X-ray studies of the Crab "Pulsar Wind" Nebula with the Chandra X-ray Observatory. We have revealed that most components of the Crab Nebula are temporally variable in their shapes with different time scales, and the X-ray spectrum varies across the nebula. I will discuss these results with our interpretations. At last, I will also present our observational result of Titan transit of the Crab Nebula.

Seminars are also held at JAC, CFHT, and IfA.
