Abstract:
We present the discovery of a candidate of giant radio-quiet Lyα
blob (RQLAB) in a large-scale structure around a high-redshift radio
galaxy (HzRG) lying in a giant Lyα halo B3 J2330+3927 at
redshift z=3.087. We obtained narrow- and broad-band imaging around B3
J2330+3927 with Subaru/Suprime-Cam to search for Lyα emitters
(LAEs) and absorbers (LAAs) at redshift z=3.09±0.03. We detected
candidate 127 LAEs and 26 LAAs in the field of view of 31x24arcmin2
(58x44 comoving Mpc).
Description:
We took narrow- and broad-band images centred at 23:30:12.7+39:30:41
(J2000.0) on 2007 November 09 (UT) with Suprime-Cam on the 8.2m
Subaru Telescope.
