DAWN in the media!

Congratulations to Bitten Gullberg, Albert Sneppen, and Peter Laursen for their individual presentations on the Danish morning show Go'Morgen Danmark, TV2 News and Kosmopol on TV2!






Bitten presented the upcoming Euclid launch and gave fantastic demonstrations of the spacecraft and instruments.






Albert presented the findings from his amazing research in the article Spherical symmetry in the kilonova AT2017gfo/GW170817 published in Nature.






Peter Laursen also gave a wonderful interview about JWST on the Danish TV2 program kosmopol.

Meet Kate Gould - new member of the 1st Author Pub-Club!

I am Katriona (Kate) Gould (she/her), a third year PhD student at DAWN-NBI supervised by Gabe Brammer and Francesco Valentino.

A fun fact about me is that I have run a lap of the inside of the Lovell Telescope (yes, I asked permission first, and yes, I have video evidence).

I became interested in this topic for the publication because I did a summer internship where I wrote an algorithm to find high redshift quiescent galaxies lensed by foreground galaxies. Before that, I wasn’t aware that they existed so early in the universe, and the literature didn’t say much about how they got there, so I decided to do a PhD to answer the question “why did galaxies first start to quench?” (Unfortunately I still can’t tell you…). But, after spending some time looking at high redshift quiescent galaxies in the latest COSMOS2020 catalog, I realised I first had to answer a much more pressing question: how do you efficiently select them from a data set? This led to my first paper, where I came up with a new selection method that is designed to effectively select high redshift quiescent galaxies from photometric catalogs.Jodrell Bank, Lovell telescope | The Lovell telescope at Jod… | Flickr

[ I plan to use this method to select quiescent galaxies in JWST data and study them in greater detail, and have already assisted Francesco with his work on producing an atlas of high redshift quiescent galaxies in public JWST fields, selected both using a classical method (UVJ) and my new method. ]

I think the most exciting finding from my paper is not necessarily about the galaxies themselves, but about methods: it’s only because of the developments in data quality, computing, machine learning and open source software that I was able to develop this method. We are at a really exciting time in science where we can use complex tools on beautiful data in a very easy way, which was not possible even 15 years ago when people first started finding high redshift quiescent galaxies. My method provides a fast, open source alternative way to reliably select galaxy populations, which has proved quite difficult in the past.

Danish Traditions & Culture



Vintergækker og Erantis - Mit Hus Min HaveThe vintergækker (snowdrop flower) is considered the first flower of the year in Denmark. The white delicate flower can be found in most cities and in Danish nature, where it often blooms in the early days of February. The vintergækker did not naturally belong or grow in Danish nature. The flower naturally grows in Spain in the Pyrenees and in Kaukasus, but the flower was brought to Denmark in the 1400-century by monks and nuns.

You will also be able to find the beautiful rich yellow Eranthis buttercup flower  growing at this time of  year and standing in contrast to the white delicate snowdrop flower.


Hidden Giant Trolls


Go for a great explore of the wooden giants in the woods of Copenhagen’s suburbs.

Scattered around lush forests, meadows, and by calm waters in suburbia Copenhagen, you'll meet the tall, quirky-looking wooden sculptures which are pretty far from your typical tourist attraction.




The municipalities of the greater Copenhagen region which are homes to impressive art pieces are definitely off the beaten track. And that's exactly why artist, Thomas Dambo opted for these scenic settings locations for his sculptures built from recycled woods; to get locals out discovering and enjoying nature.
