Abstract: Cosmic noon represents the peak of cosmic star formation activity and marks the global transition of star-forming galaxies. Great achievements have been made in the past two decades in understanding the clumpy UV structures, high gas fractions, and highly turbulent disks in these cosmic noon galaxies. However, a detailed understanding of their star formation complexities, stellar substructures, gas transport, and star-formation quenching is still under debates. In this talk, I will share our recent efforts with VLT/ERIS, ALMA, NOEMA, as well as JWST in resolving the substructures and the multi-phase gas content in typical main-sequence galaxies at cosmic noon. I will discuss how these resolved properties provide insights into the internal processes driving the evolution of massive disk galaxies at cosmic noon.
