Gravitational lensing is a powerful tool for studying dark matter, the invisible substance that makes up most of the mass in the universe. Gravitational lensing occurs when a massive object bends and magnifies the light from a distant source behind it. By observing how the light is distorted, astronomers can infer the distribution and properties of dark matter.

Strong by as a probe of the -host relations in the distant Universe: arxiv.org/abs/2306.01042 -> EPFL scientists have managed to weigh, more precisely than any other technique, a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens: actu.epfl.ch/news/weigh-a-quas - detection of strong gravitational lensing quasars is expected to multiply with the launch of Euclid this summer.

Thanks to gravitational lensing, astronomers have witnessed a supernova explode five times in a row. This occurs when a massive object bends the light from a distant source. The repeated observations could help measure the expansion rate of the universe.

Does reveal 's nature? - The best evidence for dark matter is astrophysical and indirect. Do new lensing observations point to ultra-light, wave-like dark matter?

🌌 New Lecture! 💫 Discover , learn about the II experiment & more from the @DESYnews lecture at enabla.com/pub/686/about 🎥

🗣 Don't be shy; ask your questions on Enabla and get answers from the lecturers themselves! Let's learn together!🤩

What is dark matter, and what are some current methods scientists are using to detect it? In this lecture, we explore the topic of this elusive substance that makes up approximately 85% of the matter in the universe. We discuss the evidence for the existence of dark matter, including gravitational lensing and the stability of galaxies, as well as the challenges in detecting it due to its lack of interaction with ordinary matter. We then focus on a particular candidate for dark matter called axions and describe an experiment aimed at detecting them using high-power lasers and strong magnets cooled to extremely low temperatures. The ALPS II experiment will significantly improve the sensitivity to a possible axion signal and could therefore provide crucial insight into the nature of dark matter. We also briefly discuss other methods for detecting dark matter, such as observing astrophysical processes. Finally, we consider the implications of dark matter for our understanding of the universe and the future directions of research in this exciting field. The lecture was given during the DESY Ukraine Winter School in February 2023.
