Symposium on "All-Inclusive Active Galactic Nuclei (AGN)"
Status / Challenges:
Observational studies of AGN cover the entire electromagnetic spectrum from X-rays to radio wavelengths. Additionally, with blazars suggesting a connection to neutrinos, AGN studies also reach into the domain of multi-messenger astronomy. Investigating the properties of AGN allows us to further understand the black-hole and host galaxy connection which is critical to answering some open questions related to how galaxies evolve. We wish to bring together the latest results in both observations and simulations, and (particularly) to showcase southern-hemisphere telescopes (MeerKAT, SALT, HESS, VLT, ALMA, MWA, SKA* , etc). We also wish to discuss publication of ‘null results’, and to promote a hybrid format for aiding accessibility, inclusion, and sustainability during the climate crisis (which disproportionately affects the African continent). GA 2024 will be 5 years after IAU Symposium 356 (held in Ethiopia), and so an excellent follow-up to the previous AGN discussion and outreach that took place there.
* The GA is around the time of array assembly 0.5, and array assembly 1 (8 dishes, 18 low stations) is only a few months after the GA

Gas in Galaxy Evolution in the SKA-Precursor Era
Status / Challenges:
Idea for focus meeting: With their wide frequency coverage, high resolution, and wide-field imaging capabilities, SKA precursor radio telescopes are enabling unprecedented studies of the gas in galaxies and its role in galaxy evolution over cosmic time. As we look forward to the beginning of SKA science observations, it is time to take stock of the current state of the field by highlighting recent key results from HI precursor surveys and predictions from state-of-the-art models of galaxy evolution to inform directions for HI science with the SKA.
Actions:
Propose the symposium
Potential Stakeholders:
Sarah Blyth (UCT), D.J. Pisano
Egyptian Large Optical Telescope (ELOT)
Status / Challenges:
Idea for a focus meeting; To bring the attention of the astronomical community to the upcoming 6.5m ELOT and its importance to Egypt and the astronomical community worldwide. ELOT is expected to fill the observational gap between Asia and Chile and between Europe and South Africa. More than 300 photometric nights are expected from ELOT. A lot of work needs to be done to match between ELOT optical design, its attached astronomical instruments and site optical characteristics to fill this gap and to maximize the importance of this telescope.
Actions:
- Advertise the meeting idea to garner community support
- Establish SOC and LOC.
- Contact possible IAU Divisions and Commissions for their support
- Contact site testing and telescope design experts in the continent and worldwide to introduce their experiences through workshops and lectures to people at NRIAG.
- Prepare for the findings reached upon in the site selection and testing of the sites already found.
Potential Stakeholders:

Earth Based Observations of Occultations and Astrometric / Photometric Follow-ups of Astroids, Comets, TNOS
Status / Challenges:
Preliminary Idea in search for observers/partners in Africa
Actions:
Organize observational campaigns about interesting objects using meter-sized telescopes. Focus in astrometry, photometry and spectroscopy.Particularly there is a significant interest in occultations on the basis of space missions, like e.g. Lucy and New Horizons, using small (20cm) portable telescopes.
