Starlightwinds is a page trying to reflect my love for astrophysics research and teaching. I'm Jon Sundqvist, Professor of Astrophysics - well, Associate at least - at Institute of Astronomy, KU Leuven. Galaxies and Cosmology complete Lecture University Course: youtube.com/playlist?list=PLQwcBRqZUpocdUyd4ieSoBZ… How I Teach? youtube.com/playlist?list=PLQwcBRqZUpodIACoxJIoF_O… What is a StarlightWind? youtube.com/watch?v=pREDgDVR21A&list=PLQwcBRqZUpof… Some of my KU LEUVEN university teaching also posted here: youtube.com/playlist?list=PLrGAIWCGSKlDXALWS_6R4Bv… Scientific content based on publicly available research from work and teaching. EU-path for fundamental research with me as PI, from Marie-Sklodowska Curie Grant Fellowship (alumni, "StarlightWinds") to ongoing ERC-CoG ("SUPERSTARS-3D"). Any views expressed here are personal and independent of the university.
