abstract
The QCD axion is expected to form dense structures known as axion miniclusters if the Peccei-Quinn symmetry is broken after inflation. Miniclusters that have survived until today will interact with neutron stars (NSs) in the Milky Way to produce transient radio signals from axion-photon conversion in the NS magnetosphere. We quantify the properties of these encounters and find that they occur frequently ($\mathcal{O}(1-100)\,\mathrm{day}^{-1}$); last between a day and a few months; are spatially clustered towards the Galactic center; and can reach observable fluxes. These radio transients are within reach of current generation telescopes and therefore offer a promising pathway to discovering QCD axion dark matter.

Time-Domain Axion Searches with Magnetic White Dwarfs
The apparent axion-photon conversion signal in PG 1015+014 TESS data is absorbed by the second harmonic of the star's intrinsic light curve, yielding no evidence for axions and a conservative coupling limit.

Gamma Rays from ALP-Photon Conversion and Inverse Compton Reprocessing in Neutron Star Magnetospheres
ALP-to-photon conversion near four pulsars produces mostly sub-MeV emission: Fermi-LAT is insensitive to the channel, COMPTEL data already exclude new parameter space at high ALP mass, and COSI could probe much more.

Direct detection of solar chameleons with electron recoil data from XENONnT
XENONnT electron-recoil data bound solar chameleons to log10 β_eff < −6.9, independent of the potential index n for inverse power-law chameleons at the dark-energy scale.

Mass-Gap Neutron Stars from Vector \texorpdfstring{$f(R)$}{f(R)} Gravity Inflationary Deformations
Using four vector f(R) gravity inflation models and nine equations of state, the TOV solver finds that the MPA1 equation of state yields neutron star maximum masses around 2.75 solar masses, inside the mass gap.
