Luminosity Dependent Evolution of Lyman Break Galaxies from redshift 5 to 3
I. Iwata, K. Ohta, N. Tamura +5
In this contribution we briefly describe our recent results on the properties of Lyman break galaxies at z~5 obtained from deep and wide blank field surveys using Subaru telescope,…
On The Spectrum and Spectropolarimetry of Type Ic Hypernova SN 2003dh/GRB 030329
K. S. Kawabata, J. Deng, L. Wang +32
Spectroscopic and spectropolarimetric observations of SN 2003dh/GRB 030329 obtained in 2003 May using the Subaru 8.2 m telescope are presented. The properties of the SN are investi…
Deep Spectroscopic Survey of Lyman Break Galaxies at z~5
M. Ando, K. Ohta, I. Iwata +3
We report results of deep optical spectroscopy with Subaru/FOCAS for Lyman Break Galaxy (LBG) candidates at z~5. So far, we made spectroscopic observations for 24 LBG candidates am…
