Data from Particle Physics experiments are collected with significant financial and human effort and are mostly unique. Experiment data are maintained by personal effort of scientists until they are judged no longer worth that effort. The tools and knowledge to interpret the data are lost as the members of the experiment move on to other projects. When later discoveries or new hypotheses for...

Merging galaxy clusters can potentially constrain SIDM models in multiple ways,
with systematics complementary to those of other astrophysical probes. I will give an overview of Merging Cluster Collaboration activities to drive down the upper limit from merging clusters: new ways of discovering and selecting merging clusters; a weak lensing and spectroscopic survey of a substantial sample of...

RX J1856.5-3754 is a radio-quiet Isolated Neutron Stars (INSs) discovered in the soft X-rays through its purely thermal surface emission. Owing to its large inferred magnetic field of ∼1013 G, radiation from its surface is expected to be substantially polarised, independently on the mechanism actually responsible for the thermal emission. A large observed polarisation degree is, however,...

The phase transition responsible for axion dark matter production can create large amplitude isocurvature perturbations which collapse into dense objects known as axion miniclusters. We use microlensing data from the EROS survey, and from recent observations with the Subaru Hyper Suprime Cam to place constraints on the minicluster scenario.

In the past years, the landscape of axion models has extended considerably beyond the original QCD axion. Axion-like particles could play a significant role in astrophysics as well as cosmology and many new experiments and observables have been proposed. The big landscape of axion models and observables generally poses a problem for obtaining coherent statistical inferences. The same holds...
