This month, GÉANT was in Ireland for HEAnet Conference 2025!
Our CEO Lise Fuhr joined the panel with Ronan Byrne (HEAnet), Heidi Fraser-Krauss (Jisc), and Dr Gerard Culley (University College Cork).
And our very own Monique Pellinkhof & Magdalena Rząca also joined the programme, unpacking the future of EU collaborations, and what the EU AI Act means for the R&E community.
👏 A big thank you to the HEAnet team for an excellent event!

Direct Measurement of Extinction in a Planet-Hosting Gap
Recent disk observations have revealed multiple indirect signatures of forming gas giant planets, but high-contrast imaging has rarely confirmed the presence of the suspected perturbers. Here, we exploit a unique opportunity provided by the background star AS209bkg, which shines through a wide annular gap in the AS209 disk, to perform transmission spectrophotometry and directly measure the extinction from gap material for the first time. By combining new VLT/SPHERE and JWST/NIRCam observations …
