Shedding new light on dark matter

No one has yet managed to show what dark matter is made of, even though it appears to make up over 80 percent of the mass in the universe. At Stockholm University a new kind of sensor is being built to study hypothetical particles called axions. If these invisible particles do in fact exist, they may provide a solution to the mystery of dark matter.

New experiment aims to turn the ghostly substance into actual light

A ghost is haunting our universe. This has been known in astronomy and cosmology for decades. Observations suggest that about 85% of all the matter in the universe is mysterious and invisible. These two qualities are reflected in its name: dark matter. Published by Andrea Gallo in The Conversation.

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.

International Women's Day 2024: Women in physics

March 8 is International Women's Day and today we want to highlight women in physics. There are many examples including Marie Curie, Maria Goeppert Mayer and Lise Meitner to Fabiola Gianotti and Lene Hau. We also mention some of the female professors of physics who belong to the Fysikum.

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.

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.

The first neutrino image of our galaxy

For the first time, researchers have produced an image of the Milky Way using neutrinos, which were observed with the IceCube telescope in the Antarctic ice. The neutrino image suggests that cosmic ray interactions are more intense in the center of our galaxy than once thought. The results are published in the journal Science.

IceCube neutrinos provide new view of a nearby galaxy

For the first time, an international team of scientists has found evidence of high-energy neutrino emission from a nearby galaxy. The galaxy, NGC 1068 (also known as Messier 77) is an active galaxy in the constellation Cetus and one of the most familiar and well-studied active galaxies. The results are published in Science.
