Prady ============ Title: Forecasting Axion signals in the Milky Way Abstract: Axions are among the leading candidates for dark matter and may convert into radio emission in neutron-star magnetospheres. We present sensitivity forecasts for detecting this signal with a 5-m radio telescope at Fan Mountain Observatory operating over 0.5?4 GHz (UHF, L, and S bands). Assuming the standard halo model, a three-year observing campaign probes previously unexplored parameter space for axion-like particles and improves the sensitivity of neutron-star radio searches by more than an order of magnitude. We describe the neutron-star population model, telescope noise model, and observing strategy used to obtain these forecasts. Initial UHF and L-band observations (0.5?2 GHz) serve as the pathfinder phase of the Axion Search with Telescope for Radio Astronomy (ASTRA), laying the groundwork for a broader experimental program. -------------- next part -------------- An HTML attachment was scrubbed...
