@TillSawala I hope I'm not too late to the party... but I'd be happy to talk about #GalaxyHalos and how we can use #PlanetaryNebulae to trace them. I could also give a lecture about integral-field spectroscopy and adaptive optics and all things #MUSE. I have recently moved to Turku, so I'd also be happy to hop on the pendolino and come by in person.
