[Okc-wp4] First EO talk of 2026

[Haakon Andresen]

Dear Everyone,

I hope you all had a nice break and a great start to the new year. The year is about to get even better, since this week marks the official start of the 2026 Extreme Objects season.

First, let me remind you that Kosta's licentiate on 20th of January at 10:00 in room FB55. He will discuss a few very interesting supernovae.

His opponent Christa Gall will talk about the complex nature of dust in supernovae on Thursday at 13:15 in A5:1003

Christa Gall
Why dust is not a parameter

Abstract: Astrophysical transients, such as massive stars exploding as supernovae (SNe) are the spotlights of the universe, which is filled with tiny solid particles, cosmic dust. Such dust absorbs and deflects this light and distorts our view of the visible universe. However, the mechanism of dust formation in SNe and reprocessing in the interstellar medium is complex, likely producing regions in galaxies with different dust properties. I will discuss current 'dusty' challenges and what we have learned from recent observations of dust in SNe and galaxies at various points in cosmic time and how these may impact deriving precise distances from Type Ia supernovae

Best,
Haakon (on behalf of the organisers)
