Statistical Properties of Multi-epoch Spectral Variability of SDSS Stripe82 Quasars
Mitsuru Kokubo, Tomoki Morokuma, Takeo Minezaki +4
We investigate the UV-optical (longward of Ly 1216Å) spectral variability of nearly 9000 quasars () using multi-epoch photometric data within the SDSS Stripe 82 region. T…
Stellar population and dust extinction in an ultraluminous infrared galaxy at z=1.135
K. Kawara, S. Oyabu, Y. Matsuoka +6
We present the detailed optical to far-infrared observations of SST J1604+4304, an ULIRG at z = 1.135. Analyzing the stellar absorption lines, namely, the CaII H & K and Balmer H l…
AKARI near- and mid-infrared spectroscopy of APM 08279+5255 at z=3.91
S. Oyabu, K. Kawara, Y. Tsuzuki +4
We present rest-frame optical/near-infrared spectra of the gravitationally lense d quasar APM 08279+5255 at that has been taken using the Infrared Camera (IRC) onboard the…
Ultraviolet Fe II emission in z ~ 2 quasars
Hiroaki Sameshima, Jose Maza, Yoshiki Matsuoka +6
We present spectra of six luminous quasars at z ~ 2, covering rest wavelengths 1600-3200 A. The fluxes of the UV Fe II emission lines and Mg II 2798 doublet, the line widths of Mg…
