Ghent University
• UV escape fraction → cosmic UV background Previous work: • Need good handle on neutral fraction Paardekooper et al. 2011,
• Coupling with radiative transfer code Razoumov & Sommer-Larsen 2010, Wise & Chen 2009
Oesch et al. 2010 Large population of z~7 dwarf galaxies
Conclusions
hydrodynamical props. ↑ Heating by SN, UV background → ionization balance → cooling/heating rate Chianti(Py) ↓ UV escape fraction High-fidelity simulations → observational domain
• WP1: code coupling • WP3: turbulence • WP5: radiation & dynamics
Benefit from collaborations with groups working on (solar) plasma physics, radiative transfer, … → CHARM
