Abstract: Understanding galaxy formation and evolution requires comprehensive observations of radiation from distant galaxies composed of stars, gas, and dust. In this talk, I will overview my recent and ongoing studies on distant Universe in scales of the cosmic structure, circumgalactic and interstellar media, and central black holes, with the optical/NIR and submm/mm facilities such as Hubble, ALMA, and JWST. First, I will present the results from the 100-hrs large program of the ALMA Lensing Cluster Survey and its implication for the origin of the CIB and the hidden side of the cosmic star-formation rate density. Next, I will talk about the Baryon cycle in and outside of early galaxies revealed by deep ALMA and JWST observations, and young quasars at z~5-9 reported one after another since the JWST began its operation, along with the discovery of a rapidly growing young quasar in a dust-enshrouded starburst at z=7.2. Finally, I will introduce ongoing JWST and ALMA programs that I have been leading as PI and a JWST large Lensing Cluster Survey in planning.
