GG seminar (FY2021)

The meeting will be held on every Friday from 10:30 to 12:00.
We use Zoom.
Mainly, we review preprints about gravitational waves, gravity theories, and related topics.
It is welcomed to discuss your own research.
We have a mailing list for announcements.
We try to use the web application “benty-fields”. If you sign in the benty fields, you can find our journal club “GG seminar”.
One presenter is assigned for each meeting. After the agenda given by the assigned presenter, we move to other topics given by voluntary presenters.
We would like to mainly use English and restate in Japanese what we have discussed. If you don’t know how to say in English, you can ask questions in Japanese.

通常, 毎週金曜日 10:30-12:00 に行います.
会議はZoomで行っています.
広く重力波に関連した最近のarXiv・話題を議論・情報共有します.
また, 気になっている論文や皆様の研究で相談したいことがありましたら, 歓迎いたします.
連絡はメーリングリストで行います.
“Benty-fields”というwebアプリケーションを利用しています．benty-fieldsのアカウントを登録して，“GG seminar”で検索すると参加希望を送信できます．
それぞれのミーティングで一人発表者を割り当てます．担当者の議題が終わったら，従来どおり，議論したい議題がある人を募ります．
英語話者が参加している場合は, 英語で行います. 英語で喋った後に日本語で内容をまとめ直しています. わからなくなれば、日本語で質問してもらってもよいです.
