In issue 9 of the IAU Catalyst, we can hear from our President, Debra Elmegreen, on Why be an IAU Member? General Secretary Jose Miguel Espinosa provides an overview of the IAU Regional Meetings in 2023. IAU Vice President Laura Ferrarese and Claus Leitherer, Chair of the IAU Resolution Committee, give us important updates on the process of actively participating in the IAU Resolutions. Hear from Boonrucksar Soonthornthum, President of Commission C1, about the Highlights on Astronomy Education and Development. For this edition’s Science Focus, we welcome Richard de Grijs on behalf of the organisation of IAU Symposium 376: At the Crossroads of Astrophysics and Cosmology: Period-Luminosity Relations in the 2020s, and Tomoya Hirota, Co-Chair of the Scientific Organising Committee for IAU Symposium 380: Cosmic Masers: Proper Motion toward the Next-Generation Large Projects Highlights. Hear from The Kavli Foundation and Kavli Prize by Kathie Bailey Director of Kavli Prize, and more.

As always, this issue also includes information on IAU publications, dates and deadlines.

The Catalyst is issued twice a year as an electronic-only bulletin. We hope you enjoy reading it and encourage both IAU members and the wider IAU community to get involved in future issues by submitting news and contributions about events or topics that you consider relevant to IAU members.

Previous issues of the IAU Catalyst are also available on the IAU website.
