Kinetic energy transfer from X-ray ultrafast outflows to mm/sub-mm cold molecular outflows in Seyfert galaxies
Misaki Mizumoto, Takuma Izumi, Kotaro Kohno
UltraFast Outflows (UFOs), seen as X-ray blueshifted absorption lines in active galactic nuclei (AGNs), are considered to be a key mechanism for AGN feedback. In this scenario, UFO…
WINERED high-resolution near-infrared line catalog: A-type star
H. Sameshima, Y. Ikeda, N. Matsunaga +13
We present a catalog of absorption lines in the z', Y, and J bands that we identified in 21 Lyn, a slowly rotating A0.5 V star. We detected 155 absorption features in the high-reso…
A newly-identified emission-line region around P Cygni
Misaki Mizumoto, Naoto Kobayashi, Satoshi Hamano +12
We present a high-resolution () near-infrared (9,100-13,500 ) long-slit spectrum of P Cygni obtained with the newly commissioned WINERED spectrograph in Japan.…
X-ray reverberation lags of the Fe-K line due to AGN disc winds
Misaki Mizumoto, Ken Ebisawa, Masahiro Tsujimoto +3
Short X-ray reverberation lags are seen across a broad Fe-K energy band in more than twenty active galactic nuclei (AGNs). This broad iron line feature in the lag spectrum is most…
Correction of near-infrared high-resolution spectra for telluric absorption at 0.90-1.35 microns
Hiroaki Sameshima, Noriyuki Matsunaga, Naoto Kobayashi +15
We report a method of correcting a near-infrared (0.90-1.35 m) high-resolution () spectrum for telluric absorption using the corresponding spectrum of a telluric…
X-ray short-time lags in the Fe-K energy band produced by scattering clouds in active galactic nuclei
Misaki Mizumoto, Chris Done, Kouichi Hagino +3
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 variabilit…
Can the relativistic light bending model explain X-ray spectral variations of Seyfert galaxies?
Misaki Mizumoto, Kotaro Moriyama, Ken Ebisawa +3
Many Seyfert galaxies are known to exhibit Fe-K broad emission line features in their X-ray energy spectra. The observed lines have three distinct features; (1) the line profiles a…
