The ATLAS Outstanding Achievement Award winners for 2025 are:

• Masato Aoki (KEK), Leesa Brown (Victoria and TRIUMF), George Chatzianastasiou (CERN and BNL), Thiago Costa de Paiva (University of Massachusetts Amherst)(not pictured), Nathan Felt (Harvard)(not pictured), Simone Francescato (Harvard), Eleni Kanellaki (Demokritos)(not pictured), Foteini Kolitsi (uniWA), Audrey Kvam (University of Massachusetts Amherst), Callum McCracken (Vancouver UBC and TRIUMF), Tomoyuki Saito (Tokyo ICEPP), Yoshiaki Tsujikawa (Kyoto) for the deployment of the complete Phase-I L1 Muon Endcap Trigger, including the NSW triggers, enabling ATLAS to run at higher pileup and gather more data in 2024.
• Doug Benjamin (Brookhaven BNL)(not pictured), Andrej Filipcic (Jozef Stefan Institute, Ljubljana)(not pictured), Michal Svatos (Prague AS), Rod Walker (Munich LMU)(not pictured) for advancing the experiment’s computing infrastructure through the integration of HPCs, which contribute substantially to ATLAS’s Run 3 computing power.
• Brian Andrew Cole (Columbia), Riccardo Longo (Urbana UI) for contributing to the installation, commissioning and operation of the ZDC detector and responding to multiple challenges in November 2024.
• Bojan Hiti (Jozef Stefan Institute, Ljubljana)(not pictured), Alissa Howard (Jozef Stefan Institute, Ljubljana)(not pictured), Xuewei Jia (Beijing IHEP), Mengzhao Li (Beijing IHEP)(not pictured), Chihao Li (CERN), Kuo Ma (USTC)(not pictured), Theodoros Manoussos (CERN), Weiyi Sun (IHEP CAS), Guilherme Tomio Saito (Universidade de São Paulo), Iskra Velkovska (Jozef Stefan Institute, Ljubljana), Xiao Yang (USTC)(not pictured), Mei Zhao (Beijing IHEP)(not pictured) for the successful design and testing campaign of the HGTD LGAD sensors that led to the start of sensor production.
• Tobias Bisanz (Dortmund) for management of pixel code and databases, improving reliability and speed of detector calibrations, contributions to operations, and substantial improvements to system stability and monitoring in 2024.
• André Rummler (CERN) for years of exceptional management of ATLAS operations, including significant interventions in 2024 to manage the recovery of the ATLAS infrastructure in the face of cooling challenges, enabling excellent data-taking efficiency.
• Huacheng Cai (Pittsburgh), Etienne Fortin (CERN)(not pictured), Davide Mungo (Toronto), Pavol Strizenec (Kosice)(not pictured) for successful operation of the LAr detector, including contributions to online software and detector control systems, while commissioning the digital trigger.
