We are pleased to announce that the infrared astronomical
instrument "SIRIUS", which has been developed
under the collaboration between Nagoya University,
NAOJ, NCU, and others for the last two years, has obtained
its first light on the UH 88 inch telescope on August 10, 2000.
SIRIUS, employing three science-grade Rockwell 1024x1024 HgCdTe
arrays, can simultaneously image the same field of view
(5'x5' on UH88) in three bands at near-infrared wavelengths
(J, H, Ks bands).
Please take a look at the SIRIUS home page
for the first light (FL) images and instrument details.
We, SIRIUS development team, thank the Subaru Telescope
staff and the other related people for their support and
encouragement of this project. We also thank the UH staff,
in particular Adrew Pickles, for their support of this
first light run. Special thanks to Yamamuro-san for his
excellent optical design as demonstrated with this run,
Kawai-san for his help in making cryostat, Zenno-san for
his temperature controller, and Watanebe-san for his help on
cryogenic motors and mechanical design.
First light team members
(and short introduction to students and PDFs)
NAGASHIMA Chie (NU, D2: croystat and optics)
- SIRIUS's compact and robust cryostat is her hand-made!
NAGAYAMA Takahiro (NU, D1: array control)
- SIRIUS is a first system with Messia IV and MACS.
Its usability is shown by him with this run.
NAKAJIMA Yasushi (NU, PDF: reduction software)
- The beautiful FL images on the Web are from his fingers!
NAKAYA Hidehiko (NAOJ, PDF: array electronics)
- You know his great contributions to Messia IV and MACS.
