Abstract

We report the first search for the Sagittarius tidal stream of axion dark matter around 4.55 μeV using CAPP-12 TB haloscope data acquired in March of 2022. Our result excluded the Sagittarius tidal stream of Dine-Fischler-Srednicki-Zhitnitskii and Kim-Shifman-Vainshtein-Zakharov axion dark matter densities of ρa0.184 and 0.025 GeV/cm3, respectively, over a mass range from 4.51 to 4.59 μeV at a 90% confidence level.
