ADMX: Run 1c HiRes Analysis

The Axion Dark Matter eXperiment (ADMX) aims to detect axions within the galactic halo from their conversion to microwave photons inside a resonant cavity permeated by a strong magnetic field. Run 1c is the most recent data run, covering approximately 0.8--1 Ghz. ADMX has two primary analysis channels: Medium and High Resolution (HiRes), with frequency resolutions of 200 Hz and 20 mHz, respectively. The HiRes channel is sensitive to flows of non-virialized axions that may exist within the Milky Way halo. These flows are expected to have very low velocity dispersion, leading to correspondingly narrow peaks in the measured power spectra. Further, they may also contribute significantly to the local density of dark matter. A search for such flows in the Run 1c data has been performed at spectral resolutions of 20, 40, and 1000 mHz. These allow us to probe a broader range of galactic halo models and their structure. This talk will cover the motivation for HiRes, the analysis process, results for the run 1c dataset, and future work.
