In the standard cosmological model, halo substructure or subhalos are predicted to be largely abundant inside larger halos, for example, galaxies such as ours, and are thought to form first and later merge to form larger structures. Dwarf satellite galaxies?the most massive exponents of halo substructure in our own galaxy?are already known to be excellent targets for dark matter searches, and indeed, they are constantly scrutinized by current gamma-ray experiments in the search for dark matter signals. Lighter subhalos not massive enough to have a visible counterpart of stars and gas may be good targets as well, given their typical abundances and distances. In addition, the clumpy distribution of subhalos residing in larger halos may boost the dark matter signals considerably. In an era in which gamma-ray experiments possess, for the first time, the exciting potential to put to test the preferred dark matter particle theories, a profound knowledge of dark matter astrophysical targets and scenarios is mandatory should we aim for accurate predictions of dark matter-induced fluxes for investing significant telescope observing time on selected targets and for deriving robust conclusions from our dark matter search efforts. In this regard, a precise characterization of the statistical and structural properties of subhalos becomes critical. In this Special Issue, we aim to summarize where we stand today on our knowledge of the different aspects of the dark matter halo substructure; to identify what are the remaining big questions, and how we could address these; and, by doing so, to find new avenues for research. 610 $agamma rays 610 $aindirect searches. 610 $asemi-analytic modeling 610 $acosmological model 610 $aindirect dark matter searches 610 $aparticle dark matter 610 $aindirect detection 610 $agamma-rays and neutrinos 610 $agalactic subhalos 610 $aindirect searches 610 $astatistical data analysis 610 $asubhalo boost 610 $adark matter halos 610 $ahalo substructure 610 $astructure formation 610 $adark matter annihilation 610 $adark matter searches 610 $adwarf spheroidal satellite galaxies 610 $agalactic sub-halos 610 $asubhalos 610 $adwarf spheroidal galaxies 610 $agamma-rays 610 $acosmological N-body simulations 610 $adark matter 700 $aSánchez-Conde$b Miguel A$4auth$01326663 702 $aDoro$b Michele$4auth 906 $aBOOK 912 $a9910404076503321 996 $aThe Role of Halo Substructure in Gamma-Ray Dark Matter Searches$93037635 997 $aUNINA
