It has been suggested that radio telescopes may be sensitive to axion dark matter that resonantly converts to radio photons in the magnetospheres surrounding neutron stars (NSs). In this work, we closely examine this possibility by calculating the radiated power from and projected sensitivity to axion dark matter conversion in ensembles of NSs within astrophysical systems like galaxies and globular clusters. We use population synthesis and evolution models to describe the spatial distributions… 
Green Bank and Effelsberg Radio Telescope Searches for Axion Dark Matter Conversion in Neutron Star Magnetospheres.
Data collected from the Byrd Green Bank Telescope and the Effelsberg 100-m Telescope are analyzed to set constraints on the existence of axion DM in the highly motivated mass range between ∼5 and 11  μeV with the strongest constraints to date on axions in the ∼10-11‬‬V range.
Radio line properties of axion dark matter conversion in neutron stars
Abstract Axions are well-motivated candidates for dark matter. Recently, much interest has focused on the detection of photons produced by the resonant conversion of axion dark matter in neutron
Dark matter axion detection in the radio/mm waveband
We discuss axion dark matter detection via two mechanisms: spontaneous decays and resonant conversion in neutron star magnetospheres. For decays, we show that the brightness temperature signal,
Detecting the stimulated decay of axions at radio frequencies
Assuming axion-like particles account for the entirety of the dark matter in the Universe, we study the possibility of detecting their decay into photons at radio frequencies. We discuss different
X-Ray Signatures of Axion Conversion in Magnetic White Dwarf Stars.
It is shown that the radiated axions may convert into x rays in the strong magnetic fields surrounding the WDs, leading to observable x-ray signatures, allowing for a definitive test of the axionlike-particle explanation of the stellar cooling anomalies.
Unique Multimessenger Signal of QCD Axion Dark Matter.
The projected reach of the LISA interferometer and next-generation radio telescopes such as the Square Kilometre Array is studied to infer the dark matter density and, consequently, to predict the radio emission.
Radio signal of axion-photon conversion in neutron stars: A ray tracing analysis
Axion dark matter can resonantly convert into photons in the magnetospheres of neutron stars (NSs). It has recently been shown that radio observations of nearby NSs can therefore provide a highly
Merger of dark matter axion clumps and resonant photon emission
A portion of light scalar dark matter, especially axions, may organize into gravitationally bound clumps (stars) and be present in large number in the galaxy today. It is therefore of utmost interest
Axion-photon conversion in neutron star magnetospheres: The role of the plasma in the Goldreich-Julian model
The most promising indirect search for the existence of axion dark matter uses radio telescopes to look for narrow spectral lines generated from the resonant conversion of axions in the

Conversion of dark matter axions to photons in magnetospheres of neutron stars
We propose a new method to detect observational appearance of dark matter axions. The method utilizes radio observations of neutron stars. It is based on the conversion of axions to photons in strong
Radio Signals from Axion Dark Matter Conversion in Neutron Star Magnetospheres.
It is shown that axion dark matter may be detectable through narrow radio lines emitted from neutron stars, and the axion-photon mixing equations are solved, including a full treatment of the magnetized plasma, to obtain the conversion probability.
A travel guide to the dark matter annihilation signal
We provide a ``Baedecker'' or travel guide to the directions on the sky where the dark matter annihilation signal may be expected. We calculate the flux of high energy gamma-rays from annihilation of
