Sara Strandberg on Wallenberg Scholar and the Higgs particle

The Wallenberg Scholars program supports and stimulates some of the most successful senior researchers at Swedish universities. The grant is for five years with the possibility of a five-year extension. There are currently 88 active Wallenberg Scholars and Emil Bergholtz was recently appointed. Sara Strandberg received a five-year extension. On April 12, Sara participated in the Swedish Radio program Vetenskapsradion on the topic of the Higgs particle.

Exploding star made the Hubble telescope turn

In the latest issue of the journal Nature, researchers from Stockholm University participate in a study of a supernova explosion where the astronomers made the Hubble telescope turn and look in a different direction than planned. The ultraviolet light from the explosion shows that the exploding red giant star was embedded in gas that puffed out in the years before the final bang.

We create a digital twin of the universe to understand the Big Bang

I try to gain a full understanding of how the universe was created 13.8 billion years ago. As a cosmologist, I have the luxury of travelling out into the universe in my mind every day and see life on Earth from a different perspective. This makes it clear how precious our little planet is.

David Marsh is Vice Director of EuCAPT

EuCAPT is a European consortium for astroparticle theory. It aims to bring together European researchers in theoretical astroparticle physics and cosmology. In early February, David Marsh took over as Vice Director of the consortium. At Fysikum he is a researcher in astroparticle physics and teaches the course Quantum Phenomena and Radiation Physics.

A scientific train journey to CERN with Sara Strandberg

On 15 April, the train departs from Stockholm to Geneva and cicerones are particle physicist Professor Sara Strandberg from Fysikum and science journalist Anna Davour from Forskning & Framsteg. Participants will learn more about the smallest components of our matter with quarks, leptons and other elementary particles. CERN is the world's largest particle physics laboratory and home to the Large Hadron Collider - the world's largest particle accelerator.

Observations of Dramatic Galactic Collision Unlock Clues to the Reionization of the Universe

An international team, led by Dr. Alexandra Le Reste from Stockholm University and the Oskar Klein Centre, used the MeerKAT radio telescope to investigate processes at the origin of the Epoch of Reionization, a crucial period occurring a billion years after the Big Bang. The study, made possible by MeerKAT's increased sensitivity relative to older telescopes, reveals how galaxy mergers might have influenced the transformation of the Universe during this epoch.

A Plasma Haloscope for the Post-Inflation Axion

In Fall 2022, a consortium of the Simons Foundation, the Alfred P. Sloan Foundation, the John Templeton Foundation and the Gordon and Betty Moore Foundation published a solicitation seeking to make profound advancements in physics by means of Small-Experiments of “table-top” size. The proposal “A Plasma Haloscope for the Post-Inflation Axion”, lead by the Berkely group has been announced as one of the 11 awardees among hundreds of initial proposals, for which a total of $30M over five years has been pledged by the foundations. “With this funding and also the earlier funding by the Knut and Alice Wallenberg Foundation we’re ready to start developing and building this detector that has the potential to discover axions”, says Jón Gudmundsson, senior researcher at Stockholm and current spokesperson of the ALPHA collaboration.

OKC15 - an anniversary for physics research that lasted for three days

The Oskar Klein Centre is celebrating 15 years with an anniversary that took place on October 17-19 2023. OKC is a hub and network for physics research in Stockholm. The scientific conference covered topics in cosmology, astrophysics and particle physics. "It has been great to celebrate our successes with all our colleagues both in Sweden and the Nordic countries as well as our alumni", says Professor Ariel Goobar, Director.

Radio signal reveals supernova origin

In the latest issue of the journal Nature, astronomers from Stockholm University reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.

Star formation in distant galaxies by the James Webb Space Telescope

Thanks to the James Webb Space Telescope’s first images of galaxy clusters, researchers have, for the very first time, been able to examine very compact structures of star clusters inside galaxies, so-called clumps. In a paper published in the Monthly Notices of the Royal Astronomical Society, researchers from Stockholm University have studied the first phase of star formation in distant galaxies.

Rare sighting of a luminous jet from a star-eating supermassive black hole

Over 8 billion years ago, a star was torn apart as it got too close to a supermassive black hole. Jets of gas directed towards Earth recently made the fate of the star visible to a telescope looking for new sources of light in the night sky. The observation has led to two independent publications including researchers at Stockholm University in Nature and Nature Astronomy.
