Event Details

Dark matter is a mysterious form of matter that makes up 85% of the matter in the Universe. However, the nature of dark matter is unknown and remains one of the largest mysteries in physics. One compelling candidate for dark matter is the axion, a hypothetical particle that emerged as a solution to the Strong CP problem in Quantum Chromodynamics. Axion haloscopes search for axion dark matter in the local Milky Way through the conversion of an axion into a microwave photon in the presence of a strong magnetic field. The Axion Dark Matter eXperiment (ADMX) is one such axion haloscope and has achieved sensitivity to both benchmark models for the axion. I will be providing an overview of the ADMX haloscope as well as presenting results from the most recent run of ADMX. In addition, I will discuss developments being made to push the search for axions to higher frequencies.
