Latest news from DAWN
Tillykke til Kasper Elm Heintz, lektor ved Cosmic Dawn Center (DAWN) på både DTU Space og Niels Bohr Institutet, som netop har vundet et ERC Starting Grant til at udføre sit projekt “Charting Cosmic Dawn: The impact of primordial matter on galaxy assembly and reionization” (PRIMORDIAL). Bevillingen giver Heintz mulighed for at udvide sin forskningsgruppe med to PhD-studerende og en postdoc.
Congratulations to Kasper Elm Heintz, associate professor at the Cosmic Dawn Center (DAWN) at both DTU Space and the Niels Bohr Institute, who has just won an ERC Starting Grant to carry out his project “Charting Cosmic Dawn: The impact of primordial matter on galaxy assembly and reionization” (PRIMORDIAL). The grant will allow Heintz to expand his research group with two PhD students and one postdoc.
Using the powerful James Webb Space Telescope, an international team of researchers led by a Danish astronomy student at the Cosmic Dawn Center in Copenhagen showed that some of the most massive galaxies in the early Universe were evolving more rapidly than expected. Studying a recently-discovered enormous galaxy cluster, the “Cosmic Vine”, the astronomers found that the huge structure hosts many additional galaxies, including several massive “dead” galaxies that have already stopped forming stars.
Congratulations and an extra happy New Year to Viola Gelli for winning the “Livio Gratton” prize, Italy’s top award for the best PhD thesis in Astrophysics. The prize was awarded for Viola’s thesis “Dwarf satellite galaxies at high-redshift: physical understanding and JWST predictions”.
Professor Darach Watson of the Cosmic Dawn Center at the Niels Bohr Institute, University of Copenhagen, is among six leading European scientists recognized with the inaugural Into Change Award, one of Europe’s largest research prizes, awarded by the Danish Ministry of Higher Education and Science.
Using the James Webb Space Telescope, a team of researchers led by a Danish bachelor student has uncovered surprising new details about the fine structure of cosmic dust in nearby galaxies. This dust — tiny particles floating in space — plays a key role in how stars and planets are born, and how galaxies evolve. The new study shows that different kinds of dust clouds behave in very different ways, and even helps pinpoint the size of the smallest patterns that dust clouds naturally form inside galaxies.
During the last six months, academic employee Gaurav Kumar, together with master students Kaj Grimstrup, Liazhe Li, and Omar Rashdan, have built two radio telescopes. One of them now observed its first light, while the other will follow soon. The two telescope will be mounted on the roof of the Niels Bohr Building, to be used for student projects in the future.
Congratulations to Kasper Elm Heintz, assistant professor at the Cosmic Dawn Center, who has been selected as one of the top 100 talents in Denmark 2025 in Berlingske’s annual award for his discoveries in observational astronomy and his contribution to our understanding of the early Universe.
The first galaxies in the Universe were born enshrouded in a “foggy” gas, and could not be seen clearly until they had cleared up this fog. Using the James Webb Space Telescope, a team of researchers led by astronomers at the Cosmic Dawn Center in Copenhagen has now detected the hitherto most distant — and hence earliest — sign of this important epoch in the history of the Universe. A galaxy, seen only 330 million years after the Big Bang, has formed a bubble of transparent gas around itself, revealing that the epoch began earlier than thought. The result has been published in the prestigious journal Nature.
Mapping cosmic history: An international team of researchers, led by astronomers at the Cosmic Dawn Center in Copenhagen, has released a comprehensive study on how galaxies and their dark matter have evolved across most of the history of the Universe. Spanning 11 billion years, this unprecedented survey reveals unexpected patterns in galaxy mass, growth rates, and the relationship between galaxies and dark matter. The study challenges existing models of galaxy formation and hints at a new understanding of how these immense cosmic structures emerged.
