My research focus on studying the spectral energy distribution of galaxies at high redshift (2<z<6) in a spatially resolved manner in order to understand how they grow their stellar masses. This require high resolution and deep observations that is only recently available through matched resolution ALMA and JWST observations of mass selected galaxies and sub-millimetre galaxies(SMGs). I will obtain parameter maps in kpc scale by modeling the broadband SEDs collected at each resolution beam using energy balancing code MAGPHYS. Inferred parameter maps will be compared with spatial distribution of neutral gas (traced by [CII] line at similar resolution with ALMA), and potentially with ionized gas (traced by H-alpha, via NIRSpec cycle 2 proposal). The goal of my works are to understand the interplay of varies components within galaxies that governed by varies baryonic physics, and determined star formation which hence the growth of stellar mass. These works will be the first to study stars, multi-phase ISM, and dust of high redshift galaxies at kpc scale. I believe we can learn more about the rapid stellar mass assembly process of galaxies during the ~3 Gyr time before the peak of cosmic star formation rate(CSFR) density when CSFR was quickly ramping up. Therefore, I think my project integrate well with the Science Goal 2 of Astro3D.
