Konami's paper on M82 has been accepted.
Konami, who is a D2 student, have succeeded in compiling a paper on metal abundances in the hot plasma of starburst galaxy M82, is accepted by PASJ. The detail is shown in http://arxiv.org/abs/1108.5778. Also, Konami et al. gave an oral presentation about this topic at an international conference, "The 11th International Symposium on Origin of Matter and Evolution of […]
Katsuda's paper on Vela pulser has been accepted.
Dr. Katsuda and collaborators published a paper entitled "Suzaku detection of Diffuse Hard X-Ray Emission Outside Vela X" in Publications of Astronomical Society of Japan (available from http://arxiv.org/abs/1103.4872). Katsuda and collaborators observed the Vela pulsar wind nebula with Suzaku, and discovered that the X-ray-emitting nebula extends outside the radio-emitting nebula. This finding strongly suggests that […]
Katsuda attended Frascati Workshop 2011
Dr. Katsuda attended an international conference, Frascati Workshop 2011 "Multifrequency Behaviour of High Energy Cosmic Sources" (http://workshop2011.iasf-roma.inaf.it/), held at the Vulcano island (Italy) during May 23-28 in 2011, and gave an oral presentation. Katsuda and collaborators observed Galactic supernova remnants with Chandra (NASA) and XMM-Newton (ESA), and succeeded in measuring direct motions of shock waves […]
A paper on Gamma-ray emission from winter thunderstorms has been accepted at Journal of Geophys. Res. D.
Tsuchiya reported gamma-ray emission from winter thunderstorms, and its paper has been published from Journal of Geophys. Res. D, which can be available from here.In this paper, we estimated the distance to the gamma-ray emission region in the thunderstorms, and found the possibility that the gamma-ray emission is derived.
