Nachts auf der Sternwarte
The lecture series "Nights at the Observatory" presents an extensive program of lectures on a variety of topics on astrophysics. The lectures are accessible to the general public and are held in German or English (see program). After the talk there is a visit to the Great Refractor.
Simulationen vs. Beobachtungen - Das spektrale Battle der Galaxienentstehung
Beobachter benutzen riesige Teleskope, um möglichst viele Galaxien im größten Detail aufzunehmen. Theoretiker füttern Supercomputer mit numerischen Codes, um Galaxien in unserem Universum möglichst realistisch zu reproduzieren. Wie gut stimmen aber die echten und die simulierten Galaxien überein — und warum ist das überhaupt wichtig? Nicht selten sind sich Beobachter und Theoretiker uneinig, gerade weil sie Galaxieneigenschaften oft auf eine unterschiedliche Art und Weise bestimmen, was zu Bias führt. Deshalb ist es essenziell, einen Common Ground zu schaffen, auf dem wir echte und simulierte Galaxien vergleichen können — denn nur so können wir verstehen, wie sich Galaxien wirklich in unserem Universum entwickeln. Ich werde euch erzählen, wie sogenannte „Mock Spektren“ uns helfen, aktuelle Challenges in Beobachtungen und Simulationen im Kontext der Galaxienentstehung aufzudecken und zu lösen.
The lecture will be given in the lecture room of the University Observatory and and will also be streamed online. The link to the video stream can be found below, in the section "Livestream".
