On Monday, 28 October 2024, Lukas Zalesky successfully defended his PhD Thesis at University of Hawai'i with the title:

"The Frontiers of Galaxy Evolution in the North Ecliptic Pole: A 10 Square-Degree  Survey to Map The Growth of Stellar Mass in Galaxies Across 10 Billion Years"

The PhD Committe included: David Sanders, Sune Toft, Istvan Szapudi, David Rubin, Kenneth Chambers and Peter Gorham

Big congratulations to Lukas!

Meet Minju Lee - new member of the 1st Author Pub-Club!

Minju

Hi, everyone! I am Minju Lee, currently a Marie Skłodowska-Curie Actions Postdoctoral Fellow based at DTU.

My general research topic is galaxy formation and evolution and my expertise is submm/mm interferometry observations and analysis. My main interest has been in constraining the properties of cold-phase gas and dust, which are the direct fuels of star formation.

Fun Fact: Recently, I’ve been really into playing badminton! It’s been almost a year since I started playing (somewhat) regularly on Sunday mornings. I’m not (yet) a great player, and I often suffer from muscle pain on Mondays and Tuesdays, but I enjoy it a lot with an amazing group of people.

Please let me know if you're interested! 🙂

Since my PhD, my main interest has been understanding the formation and evolution of massive galaxies and their connection to the surrounding environment in the distant universe (when the age of the Universe is less than 6 billion years old). The majority of massive galaxies have ceased star formation (what we call 'quenched') and are often found in dense environments, like clusters. One of my ongoing projects is also relevant; it aims to improve the current understanding of gas content evolution across cosmic time through ALMA archival data mining.

Constraining massive quiescent galaxies' dust and gas properties is a new avenue to understanding quenching mechanisms in the distant universe. This is becoming an even more interesting topic with discoveries of abundant massive quiescent populations with the James Webb Space Telescope. How did they emerge, and will they stay quenched forever?

The most exciting finding of my paper is that a non-negligible amount of dust content is found in a massive quiescent galaxy. People have generally thought that for galaxy quenching, the fuel must be gone. However, recent findings, including my work, do not always support this view. Insights from simulations suggest that different quenching mechanisms may play a role, leading to varying dust (or gas) depletion timescales after the onset of quenching.

However, we need more samples to confirm this!

Danish Traditions & Culture

The Hubertus Hunt

The Hubertus Hunt is an annual event that has taken place on the first Sunday in November since the foundation of the Danish Sport Riding Club in the 1900s. This year it will be held on Sunday the 3rd of November.

The event is held in Dyrehaven, north of Copenhagen, and attracts up to 40,000 spectators and 200 riders. The Hubertus Hunt is a symbolic continuation of the old par force hunts, for which Dyrehaven was originally designed. The royal family still attends the spectacle and watches from the Hermitage Hunting Lodge, before presenting the prize to the winner of the hunt.

The Hermitage Plain’s unique star-shaped path system was built in the 1680s by King Christian V. On the highest point on the plain is the Hermitage Hunting Lodge, originally known as the Hermitage Castle, built by King Christian VI in 1734.

The route: The start is always by Peter Liep's House in the Deer Park, and from there the 13-kilometer wild chase goes through the woods. The fox tails (riders with fox tails, no real fox is chased!) show the way. There are a total of 35 obstacles including the famous and challenging crossing of the pond (where the riders tends to fall into the water).
