Lab tours take place on Thursday morning. If you signed up please join
- 10:00 AM: Mark Pearce - Balloon- and satellite-borne lab
- 10:30 AM: Jörn Mahlstedt - XENON: Dark matter lab
- 11:00 AM: Jon Gudmundsson - Cosmology and axions lab
Meeting point is in front of the Oskar Klein Auditorium for all three tours.
Cosmology and axions lab tour (with registration)
Jon Gudmundsson - about 30 min
The activates in our group are motivated by fundamental questions in cosmology. We are developing metamaterial-based resonator prototypes for future axion dark matter experiments, including the ALPHA experiment. We are also designing and testing various microwave absorbers, including metamaterial absorbers, that are critical for telescopes that are observing the cosmic microwave background. During a visit to our lab, we will show the various prototypes that we have be developing over the last few years, discuss how they work, and hopefully give some fun anecdotes about our experiences working in the lab.

XENON: Dark matter lab tour (with registration)
Jörn Mahlstedt - about 25 min
From astrophysical observations over the last 100 years we have learned that the stars, planets and all the matter which surrounds us only make up 5% of the total energy density in the universe. The unknown 95% consist of the invisible dark matter and the even more mysterious dark energy. I will discuss how we try to find dark matter using a big detector 1400m under a mountain in Italy with the most sensitive light detectors in the world. These photosensors we test in our dark matter lab in Stockholm, the destination of our tour.
Sign up here.
Balloon- and satellite-borne lab tour (with registration)
Mark Pearce - about 20 min
In our lab we develop balloon- and satellite-borne instruments for the study of cosmic radiation. Our current focus in on X-ray polarimetry, which is a burgeoning field in high-energy astrophysics. As well as facilities for instrument development, the lab also houses test infrastructure provided by the KTH Space Centre, which allows detectors to be tested in a simulated space environment.

VR of our local Universe (drop in)
Stuart McAlpine, Ludvig Doeser
Come and take a look at the Universe in a totally new way! At the Cosmology AI group at the OKC we are developing sate-of-the-art novel methods to reconstruct our Universe from scratch, in a computer. Once reconstructed, we can explore our Universe's 'digital twin' both for scientific insight, and for outreach. We are in the process of developing a full Virtual Reality tour of our Local Cosmos, a demonstration of which will be available in FB53 on Thursday morning.
