Physikalisches Kolloquium

Institut für Physik

16:15 Uhr s.t., HS KPH

Prof. Dr. Laura Kreidberg, Max Planck Institute for Astronomy, Heidelberg
The recent launch of the James Webb Space Telescope (JWST) has revolutionized the field of exoplanet atmosphere characterization, thanks to its unprecedented sensitivity and broad wavelength coverage. In this talk, I will give a tour of the latest JWST results for transiting exoplanets, from gas giants down to rocky worlds. For the largest planets, I'll focus on the complex physical processes recently revealed in their atmospheres, including photochemistry, 3D effects, and cloud formation. Pushing down to smaller worlds, I'll share the first measurements of chemical composition for the elusive sub-Neptune population; and finally give an update on which (if any) rocky planets have atmospheres at all.

PRISMA+ Colloquium

Institut für Physik

PD Dr. Teresa Marrodan, MPI Heidelberg
The nature of dark matter is one of the most important open questions in modern physics. Astronomical and cosmological measurements provide strong evidence for its existence. Despite the many hypothetical candidate particles that have been proposed, experimental efforts have so far yielded only null results. Direct detection is a promising method for determining the nature of this dark component of the Universe. It allows, for example, to probe the existence of WIMPs (Weakly Interacting Massive Particles) via their elastic scattering off target nuclei down to tiny interaction cross sections. Several experimental strategies have been developed to measure the small recoil induced by dark matter interactions, with liquid xenon TPCs being one of the most successful. This talk will discuss the status and main results of XENONnT and outline future plans with the DARWIN/XLZD observatory.
