6Li/7Li estimates for metal-poor stars
A. E. Garcia Perez, W. Aoki, S. Inoue +3
The presence of the lithium-6 isotope in some metal-poor stars is a matter of surprise because of the high values observed. Non-standard models of Big Bang nucleosynthesis and pre-…
NEAR-IR Spectroscopy of Young Stars in the Braid Nebula Star Formation Region in Cygnus Ob7
Colin Aspin, Tracy L. Beck, Tae-Soo Pyo +8
We present 1.4 to 2.5 um integral field spectroscopy of 16 stars in the Braid Nebula star formation region in Cygnus OB7. These data forms one aspect of a large-scale multi-wavelen…
Radio Bursts Associated with Flare and Ejecta in the 13 July 2004 Event
S. Pohjolainen, K. Hori, T. Sakurai
We investigate coronal transients associated with a GOES M6.7 class flare and a coronal mass ejection (CME) on 13 July 2004. During the rising phase of the flare, a filament erupti…
Microstructure and kinematics of H2O masers in the massive star forming region IRAS 06061+2151
K. Motogi, Y. Watanabe, K. Sorai +14
We have made multi-epoch VLBI observations of H2O maser emission in the massive star forming region IRAS 06061+2151 with the Japanese VLBI network (JVN) from 2005 May to 2007 Octob…
High redshift galaxy surveys
Masanori Iye
A brief overview on the current status of the census of the early universe population is given. Observational surveys of high redshift galaxies provide direct opportunities to witn…
Properties of X-ray selected Broad Absorption Line Quasars
A. J. Blustin, T. Dwelly, M. J. Page +6
Broad absorption line quasars (commonly termed BALQSOs) contain the most dramatic examples of AGN-driven winds. The high absorbing columns in these winds, ~10^24 cm^-2, ensure that…
