      We report the discovery of a giant Lyα emitter (LAE) with a Spitzer/Infrared Array Camera (IRAC) counterpart near the reionization epoch at z = 6.595. The giant LAE is found from the extensive 1 deg2 Subaru narrowband ...

    • Origin of color gradients in elliptical galaxies 

      Tamura, N; Kobayashi, Chiaki; Arimoto, N; Ohta, K; Kodama, Tadayuki (2000-05)
      The origin of color gradients in elliptical galaxies is examined by comparing model gradients with those observed in the Hubble Deep Field. The models are constructed so as to reproduce color gradients in local elliptical ...
