Meeting Key Questions
- 1) What are the morphological and physical properties of the IGM/CGM from parsec to Megaparsec scales?
- 2) How were metals distributed and spread in the IGM/CGM and what does this tell us about intergalactic gas-galaxy interactions?
- 3) What determines the thermal and ionisation state of intergalactic/circumgalactic gas (hydrogen, helium, metals and molecules)?
