Master Thesis Projects
The Solar ALMA project offers a wide range of different possibilities for Master thesis projects. The focus can be on the analysis of observations, work on numerical simulations, development of analysis and image processing techniques or a combination of those. The main topic is our Sun but thesis topics related to other stars / stellar types are possible, too.
The Atacama Large Millimeter/submillimeter Array (ALMA) is a new powerful tool for observing the Sun at high spatial, temporal, and spectral resolution. These capabilities can address a broad range of fundamental scientific questions in solar physics. The radiation observed by ALMA originates mostly from the chromosphere—a complex and dynamic region between the photosphere and corona, which plays a crucial role in the transport of energy and matter and, ultimately, the heating of the outer layers of the solar atmosphere.
The Solar ALMA team at RoCS/ITA is working on observations but also numerical simulations, including development, processing, analysis, and visualisation. There are therefore many possibilities to find a thesis topic that matches well with a candidates interests and skills.
Possible examples (among many others):
- Focus on observations: Work on readily processed ALMA observations for 1-2 selected data sets with a clear scientific question. For instance, dynamics and temperature evolution of small-scale features and their possible implications for the atmospheric energy balance.
- Focus on simulations: Work on existing numerical simulations, possibly production of artificial ALMA observations (with existing programs) and analysis regarding a clear scientific question. For instance: What is the predicted observational signature of propagating shock waves in the solar chromosphere and what can be learned from corresponding (real) ALMA observations?
- Focus on instrumental effects: Simulation of instrumental effects that are applied to artificial observations (based on existing numerical simulations). Possible question: How do weather conditions (such as atmospheric water vapour) affect the quality of ALMA observations and what are possible solutions for minimizing (or correcting for) the effect?
- Focus on post-processing: Work on a selected observational data set and a corresponding artificial observation. Systematic experiments with changed imaging/post-processing parameters and strategies and analysis regarding the question, for instance, how the quality of ALMA observations can be optimized.
- Focus on stellar physics: Mostly work on numerical models for different stellar types and production of artificial ALMA observations. Analysis regarding the question: What properties of stellar chromospheres can be derived from (spatially unresolved) observations with ALMA and what are the best observing strategies?
