Welcome to my personal website. I am Akira Endo, an experimental astronomer working at the at the THz Sensing Group of the Delft Uniersity of Technology. My current research focuses on developing new types of astronomical instruments, which enable us to observe galaxies in the early universe in new ways. I take superconducting electronics and nanotechnology as my main toolbox, because I believe that there are still many unexplored properties of superconductors that can be used for detecting light, in various ways and with very high sensitivity. I currently lead a NWO Vidi program "Dawn of Superconducting Astrophotonics." This project aims at the development and astronomical science using an on-chip submillimeter-wave spectrometer DESHIMA. The goal is to probe the cosmic history of star- and galaxy-formation using DESHIMA.
