Development of a near-infrared wide-field integral field unit by ultra-precision diamond cutting
Kosuke Kushibiki, Shinobu Ozaki, Masahiro Takeda +17
Integral Field Spectroscopy (IFS) is an observational method to obtain spatially resolved spectra over a specific field of view (FoV) in a single exposure. In recent years, near-in…
Characterizing Vibrations at the Subaru Telescope for the Subaru Coronagraphic Extreme Adaptive Optics instrument
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +6
Vibrations are a key source of image degradation in ground-based instrumentation, especially for high-contrast imaging instruments. Vibrations reduce the quality of the correction…
Kilonova from post-merger ejecta as an optical and near-infrared counterpart of GW170817
Masaomi Tanaka, Yousuke Utsumi, Paolo A. Mazzali +42
Recent detection of gravitational waves from a neutron star (NS) merger event GW170817 and identification of an electromagnetic counterpart provide a unique opportunity to study th…
J-GEM observations of an electromagnetic counterpart to the neutron star merger GW170817
Yousuke Utsumi, Masaomi Tanaka, Nozomu Tominaga +57
The first detected gravitational wave from a neutron star merger was GW170817. In this study, we present J-GEM follow-up observations of SSS17a, an electromagnetic counterpart of G…
High-z gamma-ray bursts for unraveling the dark ages mission HiZ-GUNDAM
Daisuke Yonetoku, Tatehiro Mihara, Tatsuya Sawano +28
We are now investigating and studying a small satellite mission HiZ-GUNDAM for future observation of gamma-ray bursts (GRBs). The mission concept is to probe "the end of dark ages…
Excellent daytime seeing at Dome Fuji on the Antarctic plateau
H. Okita, T. Ichikawa, M. C. B. Ashley +1
Context. Dome Fuji, the second highest region on the Antarctic plateau, is expected to have some of the best astronomical seeing on Earth. However, site testing at Dome Fuji is sti…
Tohoku-Hiroshima-Nagoya planetary spectra library: A method for characterizing planets in the visible to near infrared
Ramsey Lundock, Takashi Ichikawa, Hirofumi Okita +7
There has not been a comprehensive framework for comparing spectral data from different planets.Such a framework is needed for the study of extrasolar planets and objects within th…
