Data-driven detection of astrophysical transients

Iftach Sadeh (DESY)

One of the major challenges in the study of explosive transients is their detection and characterization using multiple messengers, which often represent different physical regimes and temporal scales. I describe a novel data-driven framework, which is intended to enhance the discovery potential of current and upcoming experiments. Particularly, it is intended for near- and real-time analyses, which are essential for effective follow-up across instruments. The approach is based on anomaly detection techniques, coupling deep learning, time-series analysis, and Bayesian inference. I demonstrate applications focused on the study of gamma-ray bursts, supernovae, primordial black holes, and active galactic nuclei. These involve the combination of multiwavelength data, ranging from optical to gamma-rays, as well as neutrinos.
