Journal Article

We present a high-resolution (R ≃ 20  000) near-infrared (9100–13 500Å) long-slit spectrum of P Cygni obtained with the newly commissioned WINERED spectrograph in Japan. In the obtained spectrum, we have found that the velocity profiles of the [Fe II... Read More about A newly identified emission-line region around P Cygni.

X-ray short-time lags in the Fe-K energy band produced by scattering clouds in active galactic nuclei (2018)
Journal Article

X-rays illuminating the accretion disc in active galactic nuclei give rise to an iron K line and its associated reflection spectrum which are lagged behind the continuum variability by the light-travel time from the source to the disc. The measured l... Read More about X-ray short-time lags in the Fe-K energy band produced by scattering clouds in active galactic nuclei.

Nature of the warm absorber outflow in NGC 4051 (2016)
Journal Article

The narrow-line Seyfert 1 galaxy NGC 4051 is known to exhibit significant X-ray spectral/flux variations and have a number of emission/absorption features. X-ray observations have revealed that these absorption features are blueshifted, which indicat... Read More about Nature of the warm absorber outflow in NGC 4051.
