Machined immersion grating with theoretically predicted diffraction efficiency

Yuji Ikeda Naoto Kobayashi Yuki Sarugaku Takashi Sukegawa Shigeru Sugiyama Sayumi Kaji Kenshi Nakanishi Sohei Kondo Chikako Yasui Hirokazu Kataza Takao Nakagawa Hideyo Kawakita

APPLIED OPTICS 54(16) 5193-5202 2015年6月

An immersion grating composed of a transmissive material with a high refractive index (n > 2) is a powerful device for high-resolution spectroscopy in the infrared region. Although the original idea is attributed to Fraunhofer about 200 years ago,...

Performance Estimation of the Mid-Infrared Camera and Spectrometer Aboard SPICA

Hirokazu Kataza Itsuki Sakon Takehiko Wada Yuki Sarugaku Naofumi Fujishiro Yuji Ikeda Shinji Mitani Youichi Ohyama Naoto Kobayashi

JOURNAL OF ASTRONOMICAL INSTRUMENTATION 4(1-2) 2015年6月

The Space Infrared Telescope for Cosmology and Astrophysics (SPICA) is an astronomical mission optimized for mid-and far-infrared astronomy, envisioned for launch in the 2020s. The Mid-infrared Camera and Spectrometer (MCS) is a model instrument t...

HIGH-RESOLUTION 25 mu M IMAGING OF THE DISKS AROUND HERBIG AE/BE STARS

M. Honda K. Maaskant Y. K. Okamoto H. Kataza T. Yamashita T. Miyata S. Sako T. Fujiyoshi I. Sakon H. Fujiwara T. Kamizuka G. D. Mulders E. Lopez-Rodriguez C. Packham T. Onaka

ASTROPHYSICAL JOURNAL 804(2) 2015年5月

We imaged circumstellar disks around 22 Herbig Ae/Be stars at 25 mu m using Subaru/COMICS and Gemini/T-ReCS. Our sample consists of an equal number of objects from each of the two categories defined by Meeus et al.; 11 group I (flaring disk) and I...

Point source calibration of the AKARI/FIS all-sky survey maps for stacking analysis

Ko Arimatsu Yasuo Doi Takehiko Wada Satoshi Takita Mitsunobu Kawada Shuji Matsuura Takafumi Ootsubo Hirokazu Kataza

PUBLICATIONS OF THE ASTRONOMICAL SOCIETY OF JAPAN 66(2) 2014年4月

Investigations of the point spread functions (PSFs) and flux calibrations for stacking analysis have been performed with the far-infrared (wavelength range of 60 to 140 mu m) all-sky maps taken by the Far-Infrared Surveyor (FIS) on board the AKARI...

5 A monolithic deformable mirror with latchable mechanical actuation (LATCHAMAN) for space-borne telescopes

Keigo Enya Hirokazu Kataza Mitsuhiro Fukushima Kenji Mitsui Norio Okada Hikaru Iwashita Kanae Haze Aoi Takahashi Takayuki Kotani Tomoyasu Yamamuro Hitomi Kobayashi

INFRARED REMOTE SENSING AND INSTRUMENTATION XXII 9219 2014年

We present the concept, design, fabrication, and evaluation of a new deformable mirror (DM), which is latchable, compact, and designed to be applicable for cryogenic environments. The main body of a prototype DM was fabricated from a monolithic cu...
