Keck / DEIMOS Spectroscopy of Lyα blobs at z=3.1 Yuichi MATSUDA (Kyoto Univ.) Toru YAMADA (NAOJ) Tomoki HAYASHINO, Ryosuke YAMAUCHI, Yuki NAKAMURA (Tohoku Univ.)

Lyα blobs (LABs) The site of massive galaxy formation? Diffuse and large Lyαnebulae at high-z (Keel et al. 1999, Steidel et al. 2000,Francis et al. 2001) LABs live in proto-cluster regions (Palunas et al. 2004, Matsuda et al. 2004) A significant fraction have FIR dust emission (Chapman et al. 2001, Smail et al. 2003, Geach et al. 2005) The site of massive galaxy formation?

Lyα emitters (LAEs) Building blocks of galaxies? Compact Lyαnebulae at high-z (Pascarelle et al. 1998, Venemans et al. 2005) Young and low stellar mass (Yamada et al. 2001) No bright FIR dust emission (De Breuck et al. 2003) Building blocks of galaxies?

Connection between LAB & LAE very deep SCAM Narrowband image detection of many diffuse & extended Lyαnebulae (Matsuda et al. 2004) Continuous distribution!!

Keck/DEIMOS Spectroscopic targets (37) 36 LABs / LAEs + Wide range of spatial extents, average surface brightness, & luminosity 36 LABs / LAEs + 1 [OII] emitter

Lyα spatial extent vs Lyα velocity width strong correlation LABs (>16arcsec2) v(FWHM) > 500 km/s

LABs are hosted in the massive systems!! Interpretation of the Lyα velocity width Case 1 : Motion of gravitationally bounded gas clouds dynamical mass (LAB) ~1012 - 1013 Msun Case 2 : Gas outflow (superwind) starburst age several x 107 yr stellar mass (LAB) several x 1010 Msun LABs are hosted in the massive systems!!
