  1. Dust in Young Galaxies Peter Laursen Supervisor: Anja C. Andersen www.dark-cosmology.dk DARK Cosmology Centre| Niels Bohr Institutet | Københavns Universitet

  2. The code • Radiative transfer • Monte Carlo

  3. Results • Surface brightness maps

  4. Results • Surface brightness maps • Surface brightness • profiles

  5. Results • Surface brightness maps • Surface brightness • profiles • Spectra

  6. Dust in Young Galaxies • Star formation • Dust formation • Dust destruction • Radiative transfer

  7. Dust in Young Galaxies • Dust Extinction in Starburst Galaxies at z = 3 – 6 • Dust Creation in Supernova Explosions • Lyman a Galaxies at z = 8.8

  8. Dust Extinction in Starburst Galaxies at z = 3 - 6 • Lyman-Break Galaxies: • SFR = 10 – 1000 M☼ yr-1 • Correcting for dust with Calzetti ext. curve: • SFR increases a factor of 2 – 5

  9. Dust Extinction in Starburst Galaxies at z = 3 - 6 • Advance Monte Carlo code • Predict effect of dust as function of tsf, Z and z • Very young starbursts: No AGBs, intense UV field • Analyze and model SED of LBGs from GOODS • z = 2 – 6; X-rays to mid-IR • and Ultra-VISTA (COSMOS field)

  10. Dust Creation in Supernova Explosions • No AGB stars  SNe? • Grain formation and growth in SN remnants

  11. Lyman aGalaxies at z = 8.8 • ~no sky-lines in the near-IR • e.g., l = 1.2 mm • Simulate morphology and SB of statistical sample • Compare with VISTA observations
