Multi-phase medium in galaxy groups and clusters

Galaxy groups and clusters are the least massive systems where the bulk

of baryons are accounted for and also the most massive systems that are

gravitationally bound. They contain a wealth of galaxies sampling the

broad spectra of galaxy properties, including the most massive galaxies

(and probably the most massive supermassive black holes) and galaxies

with the highest velocities in the universe. Galaxy groups and clusters

are then ideal systems to study cosmic structure formation and the

related baryon physics in multi-phase media. In this talk, I will

summarize our works on two kinds of multi-phase objects with synergy in

galaxy groups and clusters, X-ray cool cores around the central galaxies

and stripped tails behind satellite galaxies. New results from

multi-wavelength data, including those from XRISM, MUSE and a recent

ALMA large program, will be presented, with the implications and future

prospects discussed.
