IVOA IAU Liaison Committee

Purpose

The International Astronomical Union (IAU) promotes research, communication, education and development in astronomy, through international cooperation. The IVOA has been engaging with the IAU to support the broad astronomical goals of the IAU, and to promote the value of IVOA activities to the IAU and the astronomy community. So far, a functional working group on the Virtual Observatory has been established within Division B (Facilities, Technology and Data Science), of the IAU; an MoU has been signed between the IVOA and the IAU Office of Astronomy for Development to support its activities. IVOA members gave presentations at sessions of the IAU General Assembly in August 2022 and supported the organization of the Division B meeting at the General Assembly. The purpose of this group, the IVOA-IAU Liaison Group (IILG), is to provide future coordination of these activities.

• Bruce Berriman gave an invited presentation "The Benefits of the Virtual Observatory to Underserved Communities" as part of Focus Meeting-1, Part Harnessing ground-based optical telescopes. The presentation can be found at https://zenodo.org/records/13381868 ( 10.5281/zenodo.13381867). A paper has been accepted for publication in the "Transactions of the IAU." The paper can be found at https://arxiv.org/abs/2412.07973.
• An interactive side session led by CDS entitled "Virtual Observatory Tools for Students and Educators in Africa" was presented by

  Mark Allen, Matthieu Baumann, Manon Marchand , Pooja Sharma (Strasbourg astronomical Data Centre, CDS), Priya Hasan (Maulana Azad National Urdu University Gachibowli, Hyderabad), and Bruce Berriman (Caltech/IPAC-NExScI) with the support of Patricia Whitelock (South African Astronomical Observatory and University of Cape Town). The aim of the workshop was toto enable the participants to discover and use openly available data for their research projects and educational activities.
