One of the imminent challenges for the next generation of telescopes,

such as the James Webb Space Telescope (JWST) is to detect the first

light from high redshift dwarf galaxies in the early Universe. In

order to assess the detectability of these sources, we need to predict

the properties of the first galaxies by pushing numerical simulations

to new levels of physical realism and detail.

In this talk, I will present the results of our highly-resolved

cosmological ab-initio simulations to understand the assembly process

of first galaxies under the feedback from the first generation of

stars, the so-called Population III (Pop III). I will show the

resulting key physical quantities of the first galaxies derived from

our simulations, such as their stellar population mix, star formation

rates, metallicity, and discuss their observability using the JWST.
