A link between feedback outflows and satellite galaxy suppression
Monthly Notices of the Royal Astronomical Society（2013）
摘要
We suggest a direct, causal link between the two ‘missing’ baryon problems of contemporary galaxy formation theory: (1) that large galaxies (such as the Milky Way) are known to contain too little gas and stars and (2) that too few dwarf satellite galaxies are observed around large galaxies compared with cosmological simulations. The former can be explained by invoking some energetic process – most...
