Japan's Possible Contributions for Coronagraph of the Habitable Worlds Observatory (HWO)
Keigo Enya, Kenta Yoneta, Naoshi Murakami +20
In this paper, we describe Japan's possible contributions for coronagraph of the Habitable Worlds Observatory (HWO) based on our independent study. We are considering to contribute…
Reverberation Measurements of the Inner Radii of the Dust Tori in Quasars
Takeo Minezaki, Yuzuru Yoshii, Yukiyasu Kobayashi +8
We present the results of a dust-reverberation survey of quasars at redshifts z<0.6. We found a delayed response of the K-band flux variation after the optical flux variation in 25…
Stellar Imaging Coronagraph and Exoplanet Coronal Spectrometer: Two Additional Instruments for Exoplanet Exploration Onboard The WSO-UV 1.7 Meter Orbital Telescope
Alexander Tavrov, Shingo Kameda, Andrey Yudaev +11
The World Space Observatory for Ultraviolet (WSO-UV) is an orbital optical telescope with a 1.7 m-diameter primary mirror currently under development. The WSO-UV is aimed to operat…
Science Objectives of the Ganymede Laser Altimeter (GALA) for the JUICE Mission
Jun Kimura, Hauke Hussmann, Shunichi Kamata +11
Laser altimetry is a powerful tool for addressing the major objectives of planetary physics and geodesy, and have been applied in planetary explorations of the Moon, Mars, Mercury,…
Laboratory demonstration of a cryogenic deformable mirror for wavefront correction of space-borne infrared telescopes
Aoi Takahashi, Keigo Enya, Kanae Haze +9
This paper demonstrates a cryogenic deformable mirror (DM) with 1,020 actuators based on micro-electrical mechanical systems (MEMS) technology. Cryogenic space-borne infrared teles…
Calibration of AGN Reverberation Distance Measurements
Shintaro Koshida, Yuzuru Yoshii, Yukiyasu Kobayashi +6
In Yoshii et al. (2014), we described a new method for measuring extragalactic distances based on dust reverberation in active galactic nuclei (AGNs), and we validated our new meth…
