Projekt: Weiterentwicklung der Barrierefreiheit des IWF-Webauftritts

Betreuer: Dipl.-Ing. Manfred Stachel und Mag. Alexandra Scherr

Im Rahmen des Web-Zugänglichkeits-Gesetz (WZG) verfolgt das Institut das Ziel, seinen Webauftritt kontinuierlich zu optimieren und für alle Nutzerinnen und Nutzer, einschließlich Menschen mit Sehbehinderungen, noch leichter zugänglich zu machen. In diesem 4-6 wöchigen Projekt geht es darum, die Bildbeschreibungen in deutscher und englischer Sprache weiterzuentwickeln und so die in internationalen Standards definierten Anforderungen an barrierefreie Webinhalte bestmöglich zu erfüllen. Darüber hinaus umfasst die Aufgabe die sorgfältige Überprüfung und Aktualisierung der Copyright‑Angaben der verwendeten Abbildungen. Erfahrungen im Umgang mit CMS‑Systemen, beispielsweise Typo3, sind von Vorteil und erleichtern die Umsetzung der Verbesserungen.

Project: MMS Data Exploration & Energy Budget Analysis

Supervisor: Dr. Aditi Upadhyay and Dr. Zoltán Vörös

Earth’s magnetosheath, the turbulent, shocked solar wind region bounded by the bow shock and the magnetopause, is a unique natural laboratory for studying collisionless plasma turbulence across a wide range of spatial and temporal scales. Understanding how energy cascades from large magnetohydrodynamic (MHD) scales down to electron kinetic scales, and how it is locally converted and transported by coherent structures, is a central open question in space plasma physics. NASA’s Magnetospheric Multiscale (MMS) mission, flying four identical spacecraft in a tunable tetrahedral formation, provides the highest-resolution plasma and electromagnetic field measurements ever made in this region. This project introduces the student to the MMS mission and its unique data products, develops the physical and mathematical tools needed to compute plasma moments and energy terms from particle distribution functions, and places these in the context of multi- versus single-spacecraft analysis. The culminating step is to apply the acquired skills to compute local energy proxy (LEP) terms and contribute processed, labelled data intervals to the FWF project’s growing magnetosheath database.

Project: Magnetopause Response to Interplanetary Magnetic Field Orientation Changes

Supervisor: Dr. Adriana Settino and Dr. Daniel Schmid

The Earth's magnetopause is a dynamic boundary separating the shocked solar wind plasma from the magnetosphere. The dominant coupling processes at this boundary are strongly controlled by the interplanetary magnetic field (IMF) orientation. For instance, southward IMF drives dayside magnetic reconnection, while northward IMF favors the Kelvin–Helmholtz instability. Both processes facilitate solar wind plasma entry into the magnetosphere.
The solar wind magnetic field is, however, highly variable in both magnitude and orientation. Despite extensive study of magnetopause dynamics under prolonged periods of quasi-steady IMF conditions, the transitional periods — when the IMF changes orientation — remain comparatively poorly understood. This project addresses two fundamental questions regarding this transition:

• How does the magnetopause respond to a IMF turning?
• On what timescale does the magnetopause readjust to the new IMF configuration?

Answering these questions is essential for advancing our understanding of solar wind–magnetosphere coupling under realistic, time-varying solar wind conditions and critical to understand the energy input into the magnetosphere.

Necessary knowledge: Plasma Physics knowledge would be beneficial. Programming skills in Python or Matlab are required.

Project: Neural-RT: A Neural Emulator for Radiative Transfer for Exoplanet Atmospheres

Supervisor: Dr. Amit Reza

Present and future space missions enable comparative studies of the weather and climates of ensembles of exoplanets orbiting different stars within our galaxy, where the host-star population and the chemistry-determining element abundances change. Exoplanet atmospheres are complex physio-chemical systems where cloud and gas chemistry are in close feedback loops with the local thermo- and hydrodynamics, which in turn are affected by the external radiation field of the host star and the local galactic metallicity. Complex models have been developed that are highly computationally intensive, including three major components of exoplanet atmosphere characterization: the 3D Global Circulation Model (GCM), Cloud modeling, and Radiative Transfer. This work aims to develop a Machine Learning (ML)-driven data interpretation pipeline as a fast, robust, and reliable alternative to classical components, in particular to develop a neural network (NN) emulator to accelerate the radiative transfer (RT) component, integrating with 3D GCM and cloud modelling.

Necessary knowledge: Knowledge in one or more of the following topics will be helpful: Exoplanet Atmospheric Modelling, Astrophysics, Atmospheric Science, and Machine Learning.

Am 19. August 2025 durften wir unsere diesjährigen Sommerpraktikant:innen zu einem gemeinsamen Welcome Event einladen. Bevor jede:r Praktikant:in sein/ihr Projekt kurz vorstellen durfte, gab es ein paar Kennenlernspiele. Abgerundet wurde die Veranstaltung durch eine Vorstellungsrunde der verschiedenen Forschungsgruppen am IWF. Gestärkt mit Eis und vielen neuen Ideen konnten unsere Praktikant:innen dann am Schluß noch einen Blick ins IWF Astrolab werfen.

Auch für den Sommer 2026 ist so ein Welcome Event geplant.
