| Outline of Final Research Achievements |
The aim of this study was to obtain a comprehensive picture of low-mass galaxies at redshift ~ 2, the peak epoch of galaxy growth, based on a large sample of 10,000 galaxies detected by Subaru's next generation wide-field camera Hyper Suprime-Cam (HSC) through the new narrow-band filter NB387 which is manufactured by this fund. The filter has been delivered, but due to the delay of the installation of the camera, the observation has also been delayed. Instead, I used an existing smaller sample to study several properties of z~2 low-mass galaxies including star formation activities, dust extinction, outflow, and the origin of strong Ly alpha emission. More detailed studies will be done using coming HSC data.
