First Spectroscopic Evidence for High Ionization State and Low Oxygen Abundance in Lya Emitters
Kimihiko Nakajima, Masami Ouchi, Kazuhiro Shimasaku +3
We present results from Keck/NIRSPEC and Magellan/MMIRS follow-up spectroscopy of Lya emitters (LAEs) at z=2.2 identified in our Subaru narrowband survey. We successfully detect Ha…
Gas Motion Study of Lya Emitters at z~2 Using UV and Optical Spectral Lines
Takuya Hashimoto, Masami Ouchi, Kazuhiro Shimasaku +5
We present the results of Magellan/MMIRS and Keck/NIRSPEC spectroscopy for five Lya emitters (LAEs) at z=2.2 for which high-resolution FUV spectra from Magellan/MagE are available.…
Near-infrared spectroscopy of a nitrogen-loud quasar SDSS J1707+6443
N. Araki, T. Nagao, K. Matsuoka +6
We present near-infrared spectroscopy of the z=3.2 quasar SDSS J1707+6443, obtained with MOIRCS on the Subaru Telescope. This quasar is classified as a "nitrogen-loud" quasar becau…
