Time Speaker Title Abstract and slides
11:00-11:03 Yihan Tao, André Schaaff Quick Introduction Live from this page
11:03-11:21 (15+3) Giuseppe Greco Textual MOCs and Agentic Workflows for Multi-Messenger Astronomy Within the framework of the European project ACME – The Astrophysics Centre for Multi-messenger studies in Europe, we will present a set of hands-on activities focused on the use of well-established Virtual Observatory standards and tools for multi-messenger astronomy research, SeeFull ( slides)
11:21-11:39 (15+3) Arn Marklund From pixels to dynamics: Using deep learning to infer properties of extragalactic globular clusters Upcoming wide-field photometric surveys will observe hundreds of thousands of globular clusters (GCs), posing a key challenge: deriving reliable cluster properties with methods that scale to these data volumes. By forward modeling snapshots from state-of-the-art numerical simulations into mock images, we train a deep learning algorithm, π-DOC, to simultaneously decontaminate GC images from field stars, reconstruct 2D mass maps, and infer global properties including age, distance, and ellipticity directly from multi-band photometric images. I will present π-DOC and its performance on synthetic and real data from the PHAT and PHAST surveys of M31. (slides)

11:39-11:57 (15+3) Sebastian Trujillo Gomez The challenges and rewards of developing useful discovery tools for modern astrophysics

Machine learning–assisted analysis is now widespread in astrophysics, but its scope is still narrow, mostly focusing on regression, classification, and anomaly detection tasks for processing large observational datasets. In contrast, the development of universal visualization, exploration, modeling, and discovery tools has lagged behind. In this talk I will discuss the data analysis and modeling challenges posed by modern and future astrophysics scientific workflows, and the opportunities presented by the rapid development of powerful statistical techniques originating from the field of Machine Learning. As a prototypical example, I will describe the development process of our explorative discovery tools that aim to address these challenges, and the difficulties we face in building tools that are useful, interpretable, trustable, easy to use, and general and flexible enough to be widely adopted by the research community and beyond.

11:57-12:07 (8+2) Sébastien Durna, Liza Fretel, Baptiste Cecconi LLM-assisted analysis of papers to discover named entities (instruments, datasets, quantities, etc.) We are building an annotated corpus of papers in view of a science reproducibility study. The scope is a sub-field of astronomy (heliophysics and low frequency radio astronomy). There is an annotated corpus available from ADS, but the annotation were not too well adapted to our planned task. We have thus decided prepare a new corpus, annotating with instruments, parameters, quantities and units, formulae, time and spectral coverage, figures, tables, software… all pieces that are useful for the upcoming tasks. We have used LLMs to assit us on this task and we will ask experts to validate the annotations. slides
12:07-12:27 (20) Dave Morris discussion about declaring, tagging, and citing AI contributions Examples and experiments to seed the discussion (slides)
12:27-12:30 Yihan Tao, André Schaaff Conclusion and next steps see Friday's summary
