The Impact of a Supernova Explosion in a Very Massive Binary
Jun'ichi Sato, Masayuki Umemura, Keisuke Sawada
We consider the effect of a supernova (SN) explosion in a very massive binary that is expected to form in a portion of Population III stars with the mass higher than 100.…
Large-Scale Structure of Short-Lived LymanαEmitters
Ikkoh Shimizu, Masayuki Umemura, Atsunori Yonehara
Recently discovered large-scale structure of LyαEmitters (LAEs) raises a novel challenge to the cold dark matter (CDM) cosmology. The structure is extended over more than 50 Mpc at…
Chemodynamics of Lyman alpha emitters, Lyman break galaxies and elliptical galaxies
Masao Mori, Masayuki Umemura
We report an ultra-high-resolution simulation that follows evolution from the earliest stages of galaxy formation through the period of dynamical relaxation. The bubble structures…
Luminosity Functions of Lyman-Break Galaxies at z~4 and 5 in the Subaru Deep Field
Makiko Yoshida, Kazuhiro Shimasaku, Nobunari Kashikawa +3
We investigate the luminosity functions of Lyman-break galaxies (LBG) at z~4 and 5 based on the optical imaging data obtained in the Subaru Deep Field Project. Three samples of LBG…
Secondary Star Formation in a Population III Object
Hajime Susa, Masayuki Umemura
We explore the possibility of subsequent star formation after a first star forms in a Pop III object, by focusing on the radiation hydrodynamic (RHD) feedback brought by ionizing p…
The End of the Reionization Epoch Probed by Ly-alpha Emitters at z=6.5 in the Subaru Deep Field
N. Kashikawa, K. Shimasaku, M. A. Malkan +16
We report an extensive search for Lyman-alpha emitters (LAEs) at z=6.5 in the Subaru Deep Field. Subsequent spectroscopy with Subaru and Keck identified eight more LAEs, giving a t…
