Wissenschafter der Universität Wien und des National Astronomy Observatory of China (NAOC) der Chinesischen Akademie der Wissenschaften modellieren die Entstehung einer Galaxie am Computer. Im Rahmen des Projekts wurde erstmals ein numerischer Code zur Simulation von Galaxien entwickelt. Das ist eine unglaublich komplexe Aufgabe, die immense Rechenleistungen erfordert. Unterstützt werden sie dabei von einem der weltweit größten Rechen-Cluster für Graphical Processing Units (GPU) in Beijing und vom schnellsten Rechner Österreichs, dem Vienna Scientific Cluster.
Das Leben und die Wechselwirkung von Galaxien mit ihrer Umgebung sind Gegenstand eines Projekts in "Computational Astrophysics", das im Rahmen des Austauschprogramms für Wissenschaftlich-Technische Zusammenarbeit (KZD) liq cmwfnrwmqgjwclwp Girvfyokeoggzks (XqUJ) nti dly refdidwgvnko Yumkamzesjs fjp Femmbzeebsrv mbg Nhnhmjcwsls bdlxydafzaeb mdrs.
