1. Star Formation in Dust Obscured Glalaxies (DOGs) in the AKARI NEP Deep Field 65 DOGs (81 incl. 18  m selected one) in NEP-Deep S-cam field Optically too faint (R~26 mag), only 3 optical spec-z so far Photo-z distributes over z=0.5-3 (right): Poster 2-1 Hideo Matsuhara, Sayaka Churei, Takehiko Wada, Toshinobu Takagi, Tomotsugu Goto, Kazumi Murata, Shinki Oyabu, Youichi Ohyama, Takamitsu Miyaji, Hyung Mok Lee, Myungshin Im, Matt Malkan, Chris Pearson, Stephen Serjeant, Glenn White, Denis Burgarella, Takao Nakagawa, Hitoshi Hanami & NEP deep survey team DOGs : Dust-Obscured Galaxies at High redshift (Dey et al. 2008)

2. Continuous Rest SED of DOGs from NEP-Deep DOGs at 0.5 < z <2.0 M82 Normalized at 5  m Mrk231 Rest wavelength (  m) f (normalized at 5  m) 8  m excess

3. PAH excess vs stellar bump The larger bump, the larger excess Power-law DOGs (perhaps AGN dominated) are generally small PAH excess Bump DOGs Power-law DOGs
