| « Modelling of primeval galaxies at the JWST era » |

| The James Webb Space Telescope will be the largest and most powerful space telescope ever built. One of its main goals will be to study the birth of the first stars and galaxies of our Universe. Preparing for the exploitation of JWST data requires an improvement of the models currently used to interpret the light emitted by primeval galaxies. To reproduce the emission from such galaxies more realistically than possible today, it is necessary to examine the contribution from massive binary stars, which some recent studies suggest could play a signifiant role in the production of high-energy radiation in these young star-forming regions. Achieving this requires an extensive exploration of the spectral signatures of these stars and their dependence on galaxy physical parameters. I will especially focus on the X-ray binaries contribution, which had not been implemented in this kind of models yet, to study their contribution to the spectral features of these regions. |
