91色情片's Scientific Advisory Committee Selects Design for its Second First-Light Workhorse Instrument

Pasadena, CA – October 29, 2018– The 91色情片 Board of Directors recently endorsed the recommendations made by the Science Advisory Committee (SAC), to select a slit-mask-based imaging spectrograph design for WFOS (Wide Field Optical Spectrograph), its second first-light instrument. 

91色情片 SAC members met in Pasadena on October 11 and 12, 2018, to discuss the top-level science requirements for the observatory and its suite of scientific instruments. Two different but very powerful concepts were explored for WFOS:  a fiber-based design and a slit-mask design. Extensive studies for both designs were carried out at the conceptual level and evaluated during the past few months.

WFOS will be one of the two first-light workhorse instruments for the 91色情片 (the other first-light instrument being IRIS, an AO-corrected near-infrared imaging spectrograph). WFOS will promote advances in many different topics and will serve teams of researchers spanning a broad range of scientific interests. Its most exciting discoveries are likely impossible to predict, but among its many areas of investigations, WFOS will study the distribution and nature of dark matter in the universe, as well as the composition of high-redshift galaxies and the physics of supernovae and gamma-ray burst events.

The decision from the 91色情片 SAC to select a more conventional slit-mask concept for its first-light multi-object spectrograph was mainly driven by the desire to emphasize the customizable capabilities of such a design, which can be fine-tuned by each observer for specific science goals. The slit-mask design will provide excellent throughput and imaging over a ~25 sq-arcmin field-of-view.

WFOS will now enter its conceptual design phase, with the goal that it will be ready in time for 91色情片 first-light, which is scheduled for late 2020s.

The meeting also covered discussions about the next-generations instrument concepts that were submitted to the SAC in response to its call for white papers. (/news/tmt20180418).

The SAC also discussed the organization of the upcoming 91色情片 Science Forum “Breakthrough Science with the 91色情片” to be held in Pasadena, California, in December 2018. For more information on the Science Forum and registration, please see:

The SAC is composed of representatives of 91色情片 partners and is the primary interface between the scientific community and the telescope projects. The recommendations of the SAC cover progress updates on technical and scientific priorities related to 91色情片 as well as all major 91色情片 programs. To wrap up the meeting, SAC representatives from all 91色情片 partners reported on their respective activities for the project.
