The Impact of Halo Substructure on Dark Matter Signatures

Uncovering cold dark matter halo substructure with tidal

1 Introduction.A generic prediction of cold dark matter (CDM) cosmology is the existence of a significant amount of substructure in gravitationally collapsed structures such as galaxy clusters,galaxy haloes and even dwarf galaxies (Klypin et al.1999; Moore et al.1999b,2001).On the scale of large spiral galaxies such as the Milky Way,some 500 dense clumps are expected to orbit in the halo.The splashback radius understanding the boundaries of The Impact of Halo Substructure on Dark Matter Signatures#0183;Halos are the result of a long sequence of cosmic structure formation.We think it happened like this The early Universe,after a very short period of rapid expansion called inflation,settled into its current phase of more leisurely general cosmic expansion (or Hubble flow, as cosmologists often call it).At the end of inflation,while the density of dark matteron averagehad been The splashback radius understanding the boundaries of The Impact of Halo Substructure on Dark Matter Signatures#0183;Halos are the result of a long sequence of cosmic structure formation.We think it happened like this The early Universe,after a very short period of rapid expansion called inflation,settled into its current phase of more leisurely general cosmic expansion (or Hubble flow, as cosmologists often call it).At the end of inflation,while the density of dark matteron averagehad been
