## Summary

The  aims to characterize the formation and evolution of galaxies by observing their stars, gas, and dust on resolved spatial scales. This unique survey combines kpc-resolved imaging and spectroscopy from HST, JWST, and ALMA for 18 massive main-sequence galaxies at redshifts z=4-6 with log(M/$M_\odot$) > 9.5. The goal is to study star formation, chemical properties, and extended gas reservoirs in these galaxies to connect the Epoch of Reionization with the cosmic noon. The sample of galaxies selected for this survey provides a benchmark for studying early galaxy evolution in detail. The multi-wavelength photometric and spectroscopic data collected post-Epoch of Reionization establish a foundation for understanding galaxy formation processes at high redshifts. The survey's science goals include measuring all baryon components (stars, dust, and gas) within galaxies to gain insights into their evolutionary history. With advancements in telescopes like JWST, detailed analyses of galaxies at high redshifts are now possible. Previous limitations in multi-wavelength coverage and spatial resolving power have been overcome, allowing for comprehensive studies deep into the Epoch of Reionization. Large surveys such as JADES and CEERS provide integrated spectroscopy of high-redshift galaxies to study their chemical compositions and active galactic nuclei abundances. However, challenges remain in disentangling physical processes at smaller spatial scales and comparing observations at high redshifts with local studies. Complementary observations at far-IR wavelengths are crucial for understanding ionized phases alongside cold gas and dust components. Establishing a well-studied multi-wavelength benchmark sample at z=4-6 is essential for bridging the gap between the Epoch of Reionization and cosmic noon. In conclusion, the ALPINE-CRISTAL-JWST survey presents an opportunity to delve deeper into early galaxy formation processes by studying a diverse sample of massive main-sequence galaxies at high redshifts. The data collected will contribute valuable insights into galaxy evolution across cosmic epochs, paving the way for exciting scientific discoveries in forthcoming papers.
