Towards the 2020 vision of the baryon content of galaxy groups and clusters [article]

A.Kravtsov, A. Vikhlinin, A. Zabludoff (Steward Observatory), D. Nagai, B. Benson , D. Rudd, Steven Allen
2009 arXiv   pre-print
The large masses of clusters imply that their contents have been accreted from regions of ~8-40 comoving Mpc in size and should thus be representative of the mean matter content of the universe.  ...  During the next decade sensitive multi-wavelength observations should be able to map the radial distributions of all main mass components (stars, cold, warm, and hot gas and total mass) at z<~ 1 out to  ...  Stellar content. To obtain robust stellar mass measurements for cluster galaxies and ICL, deep, multi-band photometry is needed, with filters spanning the peak in the stellar component of the SED.  ...
