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.
