Ultralight Dark Matter and observable phenomena
IFPU
29 September-October 3 2025
Ultralight dark matter (ULDM) models have recently gained interest due to its small scales predictions. Their small masses may let them behave as a collection of waves, leading to new phenomena such as a suppression in the mass power spectrum on small scales, the presence of characteristic interference patterns, the formation of soliton cores, observational effects in pulsar timing data. Standard candidates are axion like particles and dilatons, but there are also viable candidates of vector and spin 2 tensors. In principle, the predictions of each candidate model must be confronted with data on all scales where the models make calculable predictions that can be tested observationally or experimentally. This Focus Week is intended to bring together experts on ULDM dedicated to the study of different observable phenomena, with the aim of contributing to identifying and characterizing observable effects relevant to the discrimination between candidate models.
