Research project Charting new physics with time-domain astronomy
Our team discovered the first ever spatially resolved strongly lensed "standard candle" supernova, iPTF16geu (Goobar et al, 2017, Science). These supernovae are used to study the composition of the Universe.
Our ability of study and understand the properties of the universe and the fundamental laws that govern its evolution is limited by our means to make observations and experiments. Technical advances in instrumentation often leads to breakthroughs. One off the most recent ones was the discovery of the acceleration universe, which points to the existence of some sort of "dark energy", which we now know makes up for 70% of the Universe. This project aims at figuring out what dark energy is!
