| 13:30 - 15:00 Weekly Seminar Galactic Genesis to Twilight: Charting Stellar Evolution in Nearby Galaxies with PHANGS-JWST Mid-IR Observations School ASTRONOMY The PHANGS-JWST survey provides an unprecedented opportunity to study the complex stages of stellar evolution in nearby galaxies through mid-infrared (Mid-IR) observations. Using high-resolution imaging, we trace the lifecycle of stars from deeply embedded regions, where young stellar objects (YSOs) are still enshrouded in dust, to more evolved stages such as post-Asymptotic Giant Branch (post-AGB) stars and HII regions. The JWST’s capabilities enable us to examine the dust emission and stellar feedback processes that occur throughout these stages. By analyzing photometric data in the mid-IR, we aim to construct a comprehensive timeline of st ... 14:00 - 15:00 Weekly Seminar Quantum information processing with color centers in hexagonal boron nitride School NANO SCIENCES Color centers in solids are among the other candidates for implementing quantum technologies ranging from quantum sensing to quantum simulations. NV, SiV, and GeV centers in diamond as well as centers in SiC have already proven successful in several aspects, even at high temperatures. Yet, the exploration for discovering alternatives is still an ongoing journey. A rather new and of growing interest is the research on color centers in two-dimensional materials that could be beneficial for quantum information processing. In particular, some optically active point defects in hexagonal boron nitride (hBN) have shown to have exceptional properties ... 16:00 - 17:00 Lecture Further Counterexamples to Zarhin's Conjecture about Microweights in Positive Characteristics School MATHEMATICS We present further families of Abelian varieties which contradict Zarhin's conjecture about mictoweights in positive characteristic.
