DAWN hosted the 1st DTU, Lund, Oslo, Chalmers, KU and Stockholm (D-LOCKS) workshop on the 11th and 12th of January 2024 at DTU.

It was successfully executed by DAWNers: Bitten Gullberg (LOC chair) Steve Gillman (co-LOC chair, SOC chair), Nikolaj Sillassen (LOC), Minju Lee (LOC), Iris Jermann (LOC) and Aswin Vijayan (LOC).

The workshop aimed to bring together observers and theorists in Scandinavia to discuss advances in modeling and observational techniques in extragalactic astronomy.

Well done everyone!


PhD Defense by Clara!

On Thursday, 18 January 2024, Clara Giménez Arteaga successfully defended her PhD Thesis in the historically Aud. A at the Niels Bohr Institute!

The PhD Committe included: Supervisor Gabriel Brammer and Evaluation Committee: Sune Toft, Pablo Pérez-González (CAB) and Erin Alexandra 'Alex' Pope (UMASS).

You can read the PhD thesis here: Resolving Stellar Populations in Galaxies Across 13 Billion Years of Cosmic Time

Welcome onboard!

welcome for Rashmi

Welcome to our new PhD Student Rashmi Gottumukkala!

We had a small informal lunch with danish pastries to welcome Rashmi to DAWN. Rashmi will be working closely with Sune Toft as supervisor.

Albert Sneppen gave a great presentation in late November for 50 young participants for a special lecture aimed the next science-passionated generation.

Only 50 participants could enter the lecture, but 250+ children had signed up in the hope of participating!

Meet David Blánquez Sesé new member of the 1st Author Pub-Club!


Hi everyone! My name is David Blánquez, a 3rd year Spanish PhD student under the supervision of Prof. Georgios Magdis who has so far focused on investigating why galaxies quench (stop forming stars) in the distant universe.

During my MSc thesis and the first part of my PhD I worked on studying the far-IR properties of quiescent galaxies, i.e. their cold interstellar medium. With the commissioning of JWST and the vast amount of data made available at DAWN, I thought it would be interesting to also explore the mid-IR emission of distant quiescent galaxies.

As a result of my publication, I have applied for more time on JWST in order to follow up on a few selected galaxies so if I’m awarded the time, surely I’ll produce a new study.

Fun fact: I never actually studied astrophysics, I come from an engineering background and during my MSc I decided to try and apply for a PhD position in Extragalactic astronomy. Luckily and unexpectedly, I got the position and here I am.

Lucky for us at DAWN too David!


My study has provided robust evidence to support the existence of dust in distant quiescent galaxies and has also shown that the mid-IR properties of quiescent galaxies are quite similar for galaxies in the local universe and those at z ~ 0.3-0.5. This means that, in the mid-IR, quiescent galaxies have not changed or evolved much in the last 4 billion years, which is approximately one third of the universe’s lifetime.

Danish Traditions & Culture


Lightworks 2021 - Copenhagen Light FestivalCopenhagen Light Festival: When a new year begins, we often seek for new purposes and new energy to re-charge our life-batteries again. But in the cold and grey winter-weather in Denmark, this calls for extra help!

The event is an annual light festival that transforms the quiet and cold winter darkness into a unique celebration of light art, lighting design and illumination in the Center of Copenhagen.

Vision - Copenhagen Light FestivalIn three weeks of February the festival presents a wide range of light based works - such as sculpture, installation, projection mapping, event and illumination created by both established and upcoming light artists, lighting designers, students and organizations.

This year, the Copenhagen Light festival will take place from 02 February - 25 February 2024. You can read more and find the official program here.

Komplet fastelavnstønde sæt - et tilbud med alt hvad du skal bruge!_______________________________________________________________________________________

"Fastelavn" is a tradition dating back to the 16th century and is a mixture of Halloween and a carnival event. Fastelavn is celebrated in February and children dress up in costumes to take turns hitting a wooden barrel filled with candy and treats. It's similar to a piñata, although instead of sweets, a live black cat was traditionally inside of the barrel. (But don't worry! Nowadays, the cat has been switched out for the sweets and the barrel is simply decorated with a painted version of a black cat).

The barrel ritual ("Slå katten af tønden") has been practiced for centuries and the same rules still apply today. The game continues until the entire barrel is broken. The one who knocks the bottom off the barrel (causing all of the candy to spill out) becomes the kattedronning ("queen of cats"); the one who knocks off the last piece of the barrel becomes the kattekonge ("king of cats"). Historically, it was believed that beating the barrel and chasing the black cat symbolized demolishing evil and chasing it away. This was practiced up until the 1800s, with the last known event occurring in the 1880s. The cat was not killed, but allowed to escape when the barrel was broken. The practice was also popular in Holland and similar events were known to take place in Germany, called "Katzenschlagen”.

Today, Fastelavn is mostly a fun tradition kept alive by young children at daycare institutions and primary schools. The best part of Fastelavn for adults is the Fastelavnsboller (sweet choux buns with thick cream or jam in the middle) Read more about Fastelavn, its origin and its traditions here.
