Gravitational waves promise a new window into the highest-energy events in the evolution of the universe. The recent LIGO/Virgo detections of gravitational waves from the mergers of binary black holes and binary neutron stars have ignited interest in the future direction of gravitational wave astronomy.

The space-based Laser Interferometer Satellite Antenna (LISA), due for launch in 2034, will enable direct detection of gravitational waves of frequencies around a milliHertz. This frequency range makes LISA sensitive to stochastic gravitational wave backgrounds produced by unknown physics operating in the early universe, including first-order phase transitions at the electroweak scale.

This Nordita program will bring scientists together to engage in an effort to characterize and detect sources contributing to the gravitational wave background from the early universe, and the implications for new physics at the TeV scale and beyond.

Preliminary Schedule

Week 1 (26.8 - 30.8): Inflation, cosmic strings, and probes of high-energy and gravitational physics.
Week 2 (2.9 - 6.9): Cosmological phase transitions, primordial turbulence and relic magnetic fields.
Week 3 (9.9 - 13.9): Data analysis for early Universe sources
Week 4 (16.9 - 20.9): Conference 


Nordita provides a limited number of rooms in the Stockholm apartment hotel BizApartments free of charge for accepted participants.

Please be aware that unfortunately, scammers sometimes approach participants claiming to be able to provide accommodation and asking for credit card details. Please do not give this information to them. For successful applicants, Nordita will be in touch via email regarding accommodation. If you are in any doubt about the legitimacy of an approach, please get in contact with the organisers.
