SKA-JP Joint Science Working Group Meeting “Cosmic Magnetism”
The Domestic SKA-JP workshop of “Cosmic Magnetism” was held by members of the Science Working Groups of Pulsar, Transient, Interstellar medium, and Cosmic Magnetism at a hot spring resort in Zao, Yamagata from 27-29 November.
Thirty-six participants got together from all over the country and there were 23 talks and 5 poster presentations. The programme consisted of sessions on Pulsar, Transient, Cluster of Galaxies, Galaxies, interstellar medium, and Faraday Tomography. We had six invited speakers, who presented overview of recent results on individual scientific fields. In the pulsar session on the first day, Shimpei Shibata from Yamagata university presented an overview of pulsar studies and introduced a great variety of pulsar observations, and there were also discussions on gravitational waves and pulsar observations with telescopes in Japan. Kei Kotake, from Fukuoka University, gave a talk on the recent study of supernovae and showed that the important parameter of the explosion is the compactness which is the ratio of mass to radius of the progenitor. Tomonori Totani from University of Tokyo reviewed one of the recent hottest topics, Fast Radio Burst (FRB), and participants discussed its origin and the possibilities of future research using the SKA and its precursors. Kengo Tachihara from Nagoya University talked about the latest research on the interstellar medium and magnetism. In addition to the scientific talks, there were data reduction tutorials of radio polarisation and radio pulse on the first day. Most of the participants spent enjoyable evenings staying in dormitory-type rooms and having frank discussions.
SKA-JP Engineering Regional Workshop in Kagoshima
SKA-JP Engineering Working Group is organising the SKA-JP engineering regional workshop, which will be held in Kagoshima University at Kagoshima prefecture on the 17th December 2016. Though scientific activity towards SKA era has greatly increased in Japan, engineering activity related to the SKA has not been enough yet. This workshop will aim to kick off to discuss what is the possible engineering contribution to the SKA that can come from Japan. The workshop will consist of several invited presentations and contributing talks from academic institutes as well as industries. All speakers are also requested to prepare their posters, with which the organisers encourage participants to have face-to-face discussions in coffee break time. It is also planned to discuss how Japan can take part in the engineering development of the SKA project. In this regional workshop, we focus on synergies between Department of Science and Department of Engineering in universities, as well as with regional industries.
SKA-JP Science Workshop on galaxy evolution and cosmology
The Japanese SKA workshop on galaxy evolution and cosmology on 7-9 January will be held at Aso, Kumamoto, Japan. This is the fourth workshop on this particular science theme, which began in 2013 and has been coordinated by the SKA-Japan sub-science group on galaxy evolution and cosmology (chair: Kenji Hasegawa, Nagoya University). Main topics of this workshop include galaxy formation and evolution, active galactic nuclei, first stars and galaxies, Epoch of Reionization and cosmology. Recently the group joined the Murchison Widefield Array (MWA) project and formed the MWA-Japan consortium. Thus, our study with this “SKA 0” has already begun and one of the foci is the report of our initial activities with the MWA and the discussion of the future plan considering both the SKA and MWA. Another focus is the potential of the synergy between the SKA (MWA) and facilities of other wavelengths such as Subaru, ALMA, KAGRA and TMT, including an ongoing synergy project between the MWA and Subaru on the study of Epoch of Reionization. In order to stimulate the discussion and expand the SKA-Japan consortium, we will invite speakers from a broad range of Japanese astronomical community.
