Description
Axion relic pockets (ARPs) can form in cosmic phase transitions and comprise all of dark matter. The pocket interiors are filled by the false vacuum phase, stabilised against collapse by a hot, kinematically trapped axion gas: ARPs are balloons filled with relativistic axions. I will review the theory and phenomenology of ARPs, and report on recent progress in understanding their formation and stability when the axion couples to matter, including prospects for observable signatures at terrestrial experiments and astronomical observatories.
