Recent Results from ADMX Run1C

One of the largest mysteries in physics is the nature of dark matter in our Universe. The axion is a well motivated candidate for dark matter that also solves the Strong CP problem. Axion haloscopes have been demonstrated as one of the best means of searching for dark matter axions. The ADMX halsocope has even managed to exclude the compelling but weakly coupled DFSZ axion. Most recently, ADMX completed a search for axions in the 3.3-4.2 μeV mass range, and this talk will discuss the results of that run.
