MAGIS (Measuring Abundances of red super Giants with Infrared Spectroscopy) project I. Establishment of an abundance analysis procedure for red supergiants and its evaluation with nearby stars
Daisuke Taniguchi, Noriyuki Matsunaga, Naoto Kobayashi +11
[Abbreviated] Context. Given their high luminosities (L>~10^4Lsun), red supergiants (RSGs) are good tracers of the chemical abundances of the young stellar population in the Milky…
The globular cluster VVV CL002 falling down to the hazardous Galactic centre
D. Minniti, N. Matsunaga, J. G. Fernandez-Trincado +15
Context. The Galactic centre is hazardous for stellar clusters because of the strong tidal force. Supposedly, many clusters were destroyed and contributed stars to the crowded stel…
Shock Excitation in Narrow Line Regions Powered by AGN Outflows
Misaki Mizumoto, Hiroaki Sameshima, Naoto Kobayashi +10
Outflows in the Active Galactic Nucleus (AGN) are considered to play a key role in the host galaxy evolution through transfer of a large amount of energy. A Narrow Line Region (NLR…
Mg II and Fe II fluxes of luminous quasars at z ~ 2.7 and evaluation of the Baldwin effect in the flux-to-abundance conversion method for quasars
Hiroaki Sameshima, Yuzuru Yoshii, Noriyuki Matsunaga +12
To investigate the chemical abundance of broad-line region clouds in quasars at high redshifts, we performed near-infrared spectroscopy of six luminous quasars at z ~ 2.7 with the…
First detection of -- (0,0) bands of interstellar C and CN
Satoshi Hamano, Hideyo Kawakita, Naoto Kobayashi +12
We report the first detection of C -- (0,0) and CN -- (0,0) absorption bands in the interstellar medium. The detection was made using the near…
Star formation activity beyond the outer Arm I: WISE-selected candidate star-forming regions
Natsuko Izumi, Naoto Kobayashi, Chikako Yasui +2
The outer Galaxy beyond the Outer Arm provides a good opportunity to study star formation in an environment significantly different from that in the solar neighborhood. However, st…
