Physikalisches Kolloquium

Freitag, 26. April 2024 17:00 Uhr  The road to AI-based discovery in particle physics

Prof. Dr. Gregor Kasieczka, Institut für Experimentalphysik, Universität Hamburg Modern machine learning and artificial intelligence are starting to fundamentally change how we analyze huge volumes of data in particle physics and adjacent scientific disciplines. These breakthroughs promise new insights into major scientific questions such as the nature of dark matter or the existence of physical phenomena beyond the standard model. This colloquium will provide an overview of recent, exciting developments with a focus on model agnostic discovery strategies — including first experimental results, fast simulations, and foundation models that simultaneously solve multiple tasks across multiple datasets.

Astronomisches Kolloquium

Dienstag, 23. April 2024 16:30 Uhr  The Gaia mission: an exceptional astrometric, photometric and spectroscopic multi-epoch survey

Dr. Laurent Eyer, Observatoire de Geneve At the core of the ESA Gaia mission lies a comprehensive multi-epoch survey, with astrometric, photometric, spectrophotometric, and spectroscopic measurements of the entire sky. The astrometric time series provide parallax and proper motion, also impacting astrometric binary stars, and the detection of black holes and exoplanets. The photometric measurements allow us to describe the star properties and their variability in an unprecedented manner, leading to many records and impacting the distance scale. The radial velocity breaks also observational records and allows us to improve and complete the description of binaries and kinematic properties of the Milky Way. The breadth of the results of Gaia is so wide that it is nearly impossible to summarize all its aspects. I will give a review of (biased) selected topics. Those unable to attend the colloquium in person are invited to participate online through Zoom (Meeting ID: 942 0262 2849, passcode 792771) using the link: https://eu02web.zoom-x.de/j/94202622849?pwd=dGlPQXBiUytzY1M2UE5oUDRhbzNOZz09 During his visit to Heidelberg, Professor Eyer will be available for meetings by arrangement with his hosts, Saskia Hekker (saskia.hekker@h-its.org) and Michael Bazot (michael.bazot@h-its.org)
