Jonas implements machine learning techniques in his study of the Sun

"Just thinking of sizes and distances in space is just mind blowing and impossible to grasp, but also what makes astronomy so very interesting" – Jonas Thoen Faber.

Congratulations to Jonas Thoen Faber, another master students who just got is Master Degree in Astronomy from the Institute of Theoretical Astrophysics in spring semester 2022.

– I have studied UV spectrograph observations of the Solar atmosphere obtained by the space-born telescope Interface Region Imaging Spectrograph (IRIS), tells Jonas.

– The Solar atmosphere produce characteristic spectral lines due to interaction of atomic elements. With implementation of machine learning techniques, I clustered pixels into representative pixels and then looking for rare and complex spectral lines. These dynamic spectral lines were then studied in detail to further understand the motion of the plasma at different heights, he explains.

– What are the most important things you have learned in your master studies?

– Three important things I have learned during the master program is scientific thinking, to better understand a physical object I find so very interesting and finally, that a pandemic does not reduce the effective time on procrastination, Jonas says.

– What fascinates you most of astronomy?

– For as long as I can remember, I have been interested in everything that is related to space. Just thinking of sizes and distances outside the Earth's exterior is just mind blowing and impossible to grasp, but also what makes astronomy so very interesting, he confesses.

– Your "message in the bottle" to fellow master students is ...

– My best advice is to briefly ask yourself from time to time why you are doing what you are currently doing. It might not always be as easy to give a meaningful answer, but give it your best shot and challenge yourself a bit. I tend to spend a lot of time coding just to make better results or prettier plots. In the end I'm just tweaking the same parameters over and over which sometimes are unnecessary for strengthening the understanding of my work, Jonas concludes.
