I will review our galaxy cluster projects called Mahalo-Subaru and Gracias-ALMA.
Mahalo-Subaru has been mapping out star forming galaxies across cosmic times and environments with wide field observations. Gracias-ALMA has been following-up the Mahalo-Subaru samples in coordination to characterize their star formation activities. We are also expanding these programs with HSC on Subaru (HSC-HSC) and are ready to start super multi-color imaging surveys with SWIMS on TAO (SWIMS-18).
