I could talk about astronomy all day, and sometimes I get caught on camera doing so.

The locations of flares influence the habitability of exoplanets, but it is tricky to tell them on stars that look like points on the sky to us. We came up with two tricks how we can do it anyways.

Themen: Friedmann-Lemaitre Gleichung, mal wieder Entfernungsleiter, und Recherche zur Lokalen Gruppe.

Themen: Eddington-Luminosität und Olbers-Paradoxon. Außerdem ein Nachtrag zum Halbzeitprojekt.

Themen: Existenz von Supermassiven Schwarzen Löchern. Und ein kleiner Hinweis zur Halbzeit-Aufgabe.

Themen: Interstellare Materie, 21cm-Linie, Gaswolken und die Cepheiden-Methode hands-on.

Themen: Atlas of the Universe. Virialmasse. Entfernungsleiter. Alle Fehler stammen von mir.

Themen: Objekte in der Milchstraße, Sternstromparallaxe, Rotationskurve von Galaxien. Alle Fehler stammen von mir.

Here I explain how I will select five candidates for an interview for the DAAD RISE program internship position for summer 2020 that I am supervising. This post will be mostly useful for applicants, and my future application-evaluating self.

The application deadline is on Monday, Dec 16. I collected a number of questions from interested students that I'd like to share with anyone who is interested in applying, or just got curious about the title.

I've been to an astronomy conference. I'd like such conferences to happen to other PhD students (and seniors, too). Let me tell you why.

Earlier, I dramatically announced that I was about to do something against the culture of excessive flying in academia. Here, I summarize the steps I have taken in the past six weeks. I compile what I learned and some surprising insights, spot difficulties, and declare what I will do next to eventually reduce academic flying by about 80%.

I should not be okay with having complete strangers suffering from severe consequences of unpredictable weather extremes, just because I need to meet with those scientists somewhere around the globe.

Not only can astronomy and moral philosophy be thought together, they likely ought to.
