Optical to Near-IR Spectrum of a Massive Evolved Galaxy at z = 1.26 (2008)
Matsuoka, Y., Peterson, B. A., Oyabu, S., Kawara, K., Asami, N., Sameshima, H., ...
We present the optical to near-infrared (IR) spectrum of the galaxy TSPS J1329-0957, a red and bright member of the class of extremely red objects (EROs) at z = 1.26. This galaxy was found in the...
Matsuoka, Y., Kawara, K., Oyabu, S.
We have compiled the emission-line fluxes of O I 8446, O I 11287, and the near-IR Ca II triplet (8579) observed in 11 quasars. These lines are considered to emerge from the same gas as do the Fe II...

Matsuoka, Y., Oyabu, S., Tsuzuki, Y., Kawara, K.
We present results of the near-infrared (IR) spectroscopy of six quasars whose redshifts range from 0.158 to 1.084. Combined with the satellite ultraviolet data, the relative line strengths of OI...
Oyabu, S., Yun, Min S., Murayama, T., Sanders, D. B., Kawara, K., Taniguchi, Y., ...
By exploiting the far-infrared(FIR) and radio correlation, we have performed the Likelihood-Ratio analysis to identify optical counterparts to the far-infrared sources in the Lockman Hole. Using the...
