Lyman Alpha Imaging around a Hyperluminous QSO at z=2.84
[Abstract]
Ly-alpha imaging is a powerful technique to study galaxy formation at high-redshift by detecting redshifted Ly-alpha emission line with narrowband filters. I present the latest results of our Ly-alpha imaging around a hyperluminous QSO at z=2.84, namely HS1549+1919, with HSC/Subaru. We have detected >3400 LAEs within 36 arcmin from the QSO (i.e., ~1.1 deg^2 FoV). The QSO is found to reside in the center of massive overdensity of LAEs which is embedded within a large scale (~100 cMpc) structure of LAEs. We have also detected a gigantic Ly-alpha nebula around the QSO as well as many Ly-alpha blobs. The nebula is the largest and the most luminous to date and has a peculiar morphology: bubble-like structure extending several hundred kpc. After sharing the current status I present our future plans to further reveal galaxy formation in this rich environment. Your comments and suggestions are very welcome.
