In coming years, ground-based and space telescopes will jointly deliver constraints that will transform our view of the z > 6 galaxy population. This is likely to shed new light on the formation and evolution of galaxies, cosmic reionization, the growth of supermassive black holes, the emergence of dust and possibly even on the nature of the first stars. Simulations and spectral synthesis modelling of high-redshift galaxies will play a key role in both forecasting and interpreting these data. In this two-day SAZERAC SIP, we would like to bring the simulation/modelling community together to discuss some of the challenges ahead. Topics to be covered include:
Physical properties and observational signatures of high-z galaxies and AGN
Various simulation methods, strengths and weaknesses
How galaxy formation models can forecast future observations
Modeling multiphase ISM simulations
Models for various feedback mechanisms
Contributed talks will be selected to give priority to graduate students and early-career scientists. Questions and discussions among participants will be encouraged on a dedicated official Slack channel.
