On-telescope test with four Spectrograph

      Comments Off on On-telescope test with four Spectrograph

About one month has already passed since (western) new year. PFS project is keeping the efforts on development in this year to complete the instrument and start scientific operation. In the end of 2023, the four spectrograph modules were finally integrated at Subaru Telescope, National Astronomical Observatory of Japan (NAOJ), except for one near-infrared camera. After it, we carried out… Read more »

Updates on Development of Metrology Camera System

      Comments Off on Updates on Development of Metrology Camera System

“Metrology Camera System” is one of the PFS instrument subsystems under development by ASIAA (Academia Sinica Institute of Astronomy and Astrophysics, Taiwan). This is a small telescope system installed onto the Cassegrain Focus at the bottom of the Subaru telescope to look up the Prime focus, take the image of approximately 2400 back-illuminated fiber spots in one exposure with the large… Read more »

Joint work for shipping the first positioner module

      No Comments on Joint work for shipping the first positioner module

At California Institute of Technology (Caltech,  USA), the fiber positioners “Cobra” are assembled into a module (so-called “Cobra module”) by the teams from Caltech, NASA Jet Propulsion Laboratory (JPL) and Brazil in collaboration. As highlighted in the previous article, the first Cobra module has been assembled, tested and calibrated,  so will be shipped soon to Taiwan, where the Cobra modules will… Read more »

Meeting on data analysis software in Princeton

      No Comments on Meeting on data analysis software in Princeton

Written by  Naoki Yasuda (Kavli IPMU) The galaxies PFS will observe are more than 8 billion light years away and their brightness is less than one to a 10 million of the stars visible to naked eyes. To measure the properties of these faint galaxies accurately, we have to develop data analysis software which can deal with various kinds of noises included in the acquired… Read more »

Review meeting of infrastructures for controling the PFS instruments

      No Comments on Review meeting of infrastructures for controling the PFS instruments

Subaru Telescope and its instrument are, like those at many other observatories, controlled by operator and observer sitting in front of computers at the control room in the building next to the telescope enclosure. In some cases, they are operated even from the National Observatory of Japan in Mitaka, Tokyo. PFS is not a single-component instrument but an integration of… Read more »
