abstract
We present first results and future plans for the Oscillating Resonant Group AxioN (ORGAN) experiment, a microwave cavity axion haloscope situated in Perth, Western Australia designed to probe for high mass axions motivated by several theoretical models. The first stage focuses around 26.6 GHz in order to directly test a claimed result, which suggests axions exist at the corresponding mass of $110~\mu$eV. Later stages will move to a wider scan range of 15-50 GHz ($60-210~\mu $eV). We present the results of the pathfinding run, which sets a limit on $g_{a\gamma\gamma}$ of $2.02\times 10^{-12} $eV$^{-1}$ at 26.531 GHz, or 110~$\mu$eV, in a span of 2.5 neV (shaped by the Lorentzian resonance) with $90 \%$ confidence. Furthermore, we outline the current design and future strategies to eventually attain the sensitivity to search for well known axion models over the wider mass range.

Dark Matter Haloscope with a Disordered Dielectric Absorber
A disordered dielectric powder can act as a broadband dark-matter-to-photon conversion target, and the proposed DPHaSE experiment could probe QCD axions and dark photons in the 10 meV to 1 eV range.

High-Frequency Gravitational Wave Detection with Superconducting Qubits
An idealized model shows that Dicke-entangled transmon qubits at the TE212 cavity mode could reach a strain sensitivity of about 5.6e-26 at 5 GHz, scaling as n_q^{-3/4}.

Axiverse Lampposts
In a hierarchical multi-axion theory with random couplings, axion field ranges shrink with 1/sqrt(N), generic axion–SM couplings are suppressed, but the QCD axion's coupling is unsuppressed.

Searching for Axion Dark Matter Near Relaxing Magnetars
Resonant axion-to-photon conversion near magnetars could be observable with ALMA and SKA, but the predicted line strength and frequency depend heavily on which plasma model is correct.

ADAMOS: Axion Daily Modulation Searches for Dark Matter at 20 GHz
ADAMOS, a proposed 20 GHz thin-shell haloscope, would reach g_aγγ≈4.4×10^-13 GeV^-1 in 30 days and simultaneously search for daily-modulated and transient axion signals.

Gravitational Wave Spectrum from the Production of Dark Matter via the freeze-in Mechanism
Graviton bremsstrahlung during freeze-in dark matter production yields a high-frequency gravitational wave background peaking near 5.35 x 10^10 Hz, with UV freeze-in amplitudes up to Omega_GW h^2 ~ 1e-17.
