Research Abstract

Using the narrow-band filters that are manufactured with this grant, we have conducted the Mahalo-Suabru project which has been tracing large scale structures in and around distant clusters as traced by star forming galaxies. Moreover, star forming activities across different environments have been investigated in detail and it is revealed that galaxy formation takes place and propagates from cluster centers to outer regions with cosmic time.
