13. New axion haloscopes techniques to search for axion dark matter, high frequency gravitational waves and monopoles

We introduce a systematic way to calculate the spectral sensitivity of an electromagnetic axion dark matter haloscope, so instrument comparison may be achieved independent of signal assumptions and only depends on the axion to signal transduction sensitivity and noise in the instrument [1]. Furthermore, it has been shown that electromagnetic axion haloscopes have proportional sensitivity to...

33. Employing Radio Telescopes to Search for Ultralight Dark Matter

Ultralight axions and dark photons are compelling candidates for dark matter. In this talk, I will provide an overview of my recent work (arXiv:2207.05767, 2301.03622) on detecting radio-frequency axions and dark photons using radio telescopes. The detectability relies on two distinct underlying mechanisms. One mechanism involves local dark photon dark matter inducing harmonic oscillations of...

If the PQ symmetry is broken after inflation then the QCD axion mass that gives rise to the observed dark matter (DM) abundance can in principle be calculated precisely. In practice it remains a computational challenge to accurately predict the DM contribution from nonlinear features of the PQ field such as axion strings, which introduce a large hierarchy of scales between their width and the...

62. Dark Matter searches with the MAGIC telescopes

Dr Marina Manganaro

The MAGIC (Major Atmospheric Gamma ray Imaging Cherenkov) telescopes are a system of two Imaging Cherenkov telescopes located on the Canary island of La Palma. They detect very high energy (VHE, E>100GeV) gamma rays by capturing the Cherenkov light released from charged particles in the gamma-ray-induced particle showers. For many years MAGIC devoted a consistent part of the observation to the...
