Dust in Young Galaxies QuickTime™ and a decompressor are needed to see this picture. Ebeltoft, 2008 www.dark-cosmology.dk/~pela DARK Cosmology Centre Universitet | Niels Bohr Institutet | Københavns How to find them? Damped Ly absorbers, DLAs Ly emitters, LAEs Lyman-break galaxies, LBGs Sub-mm galaxies, SMGs Distant red galaxies, DRGs 2 Building the bridge Evolutionary sequence? DLA LAE LBG DRG SMG? Selection effects? LBGs/DLAs probe two diff. ends of hi-z LF Viewing angle? 3 Monte Carlo Emit photon Determine t Determine uatom Determine ^ n Escape! 4 Radiative transfer 5 Non-isotropic <ESC> 6 How about dust? 7 Inhomogeneous medium 8 Adaptive Mesh Refinement 9 Adaptive Mesh Refinement 10 Metals He, C, N, O, Ca, Si, S, Fe at different ionization levels 11 Properties of dust n: Metals condense to dust , P(,): In principle easy: 12 Properties of dust n: Metals condense to dust , P(,): In principle easy: 13 Properties of dust n: Metals condense to dust , P(,): In principle easy: 14 Properties of dust n: Metals condense to dust , P(,): In principle easy: 15 Properties of dust n: Metals condense to dust , P(,): In principle easy: 16 Properties of dust Laboratory experiments 17 Properties of dust Laboratory experiments 18
