| Outline of Final Research Achievements |
Galaxy formation models predict that galaxies form at the intersections of dark matter filaments and gas inflows along the filaments maintain the intense star-formation activities in the early Universe. To test this prediction, we made a custom narrow-band filter, NB468, for Subaru Hyper-Suprime Cam to detect Lyman alpha emitting gas filaments. Our observing program with the NB468 was aprroved in Subaru open use time (S16A). We have published 8 refereed papers on closely related scientific topic of this program.
