Research group Cosmology

Cosmology observation and instrumentation work at the department includes supernovae, the cosmic microwave background, and large surveyes of galaxies.

Cosmology observation and instrumentation work at the department includes supernovae, the cosmic microwave background, and large surveyes of galaxies. Theoretical work at the department includes the development of phenomenological aspects, and subsequent observational tests, of cosmological theories. Measurements that constrain fundamental physics are of particular interest to members of the cosmology group.

The researchers are collaborating with the Oskar Klein Centre.

Axion astrophysics and cosmology

Do axions exist, and if so, how do we find them?

Charting new physics with time-domain astronomy

We explore the cosmic content of the universe by measuring the expansion rate using supernovae as distance indicators.

GREAT: GRavitationsstrålning och Elektromagnetiska Astrofysikaliska Transienter

The direct detection of gravitational waves has opened a completely new chapter in the study of gravity and the physics of the most compact objects in nature, black holes and neutron stars, especially using the electromagnetic counterparts

Inflationary cosmology

Did inflation happen, and what caused it?

Stockholm Researchers Provide clues to solve cosmic conundrum

Why is the vast supergalactic plane teeing with only one type of galaxies? This old cosmic puzzle may now have been solved. Jens Jasche, associate professor at Fysikum, is a member of the research group of these results.

Quest for the particles behind dark matter

Scientists have been pondering the existence of dark matter – matter that does not seem to interact with light – for almost a century. Thanks to a 27.5 million SEK grant, Jón Gudmundsson and his colleagues at Stockholm University can construct a new type of detector to find axions, a type of hypothetical particles that could constitute dark matter.
