65. A self-consistent wave description of axion miniclusters and their survival in the galaxy

Virgile Dandoy

We present a solution of the Schrodinger–Poisson system based on the WKB ansatz for the wave function. In this way we obtain a description of a gravitationally bound clump of axion dark matter by a superposition of energy eigenstates with random phases. It can be applied to any self-consistent pair of radial density distribution and phase space density f(E) related by Eddington’s formula. We...

68. Novel Astronomical Observables of Axions – with baselines from kpc, Mpc, to Gpc

Chen Sun (Tel Aviv University)

Axion couplings to photons can induce photon-axion conversion in the propagation of photons, with either the presence of a magnetic field or axion relic abundance. I first will show that this conversion impacts various cosmic distance measurements, such as luminosity distances to type Ia supernovae (~Gpc scale) and angular distances to galaxy clusters (~Mpc scale). I will consider different...

90. Radio signals of dark photons from compact stars in the galactic center

Ningqiang Song

As axions, dark photons may also convert to photons in the magnetosphere of neutron stars or the corona of white dwarfs when their mass matches the plasma frequency, producing monochromatic signals even in the absence of magnetic field. For the first time, we investigate the radio signals from dark photons in the galactic center, taking into consideration the population of white dwarfs and...

91. The Grenoble/Gravitational wave & Axion Haloscope (GrAHal): Development Plan and First Results

Pierre Pugnat (LNCMI/EMFL, CNRS), Thierry Grenet (Institut Néel, CNRS)

Development plan and first results of the Grenoble/Gravitational Wave Axion Haloscope (GrAHal) will be presented. Thanks to the Grenoble hybrid magnet modular platform allowing various magnetic field configurations ranging from 9 T / 800 mm diameter up to 43 T / 34 mm diameter, the whole axion mass range 1-200 $\mu \text{eV}$ can be probed as well as the MHz-GHz frequency domain of...
