- Observation of Galactic annihilation radiation (gamma, positronium recombination lines)

- Positrons from particle interactions (accelerators / relativistic outflows in astrophysics)

- Positrons from radioactivity

- Electron-positron plasmas

- Slowing and thermalisation of positrons in interstellar space and in denser environments

- Positronium and its recombination signatures

- The annihilation process and what we can learn from it

- Positron and positronium interactions with matter

- Antihydrogen: formation, trapping and study

- Laboratory modeling of astrophysical processes
