The Wide Integral-Field Infrared Spectrograph, or WIFIS, is a unique near-infrared integral-field spectrograph with an exceptionally wide field.
When coupled with the Steward 90″ telescope on Kitt Peak, Arizona, it will have a 50″ x 20″ field-of-view (FOV). Currently existing near-infrared integral-field spectrographs (IFS) typically have very narrow FOVs because they are optimized for observations of high-redshift galaxies, which are relatively small in size.
WIFIS will have the unique capability to observe very extended objects in the near-infrared and has an etendue that is comparable to wide-field, optical IFS. Therefore, WIFIS science will be highly complementary to programs carried out by optical IFS, such as CALIFA, SAMI and MaNGA surveys.
WIFIS science includes:
At the University of Toronto, the team working on WIFIS includes Prof. Dae-Sik Moon (PI), Prof. Suresh Sivanandam (Project/Instrument Scientist), Dr. Richard Chou, and graduate students Mark Ma, Elliot Meyer, Miranda Jarvis, Bryn Orth-Lashley, and Max Millar-Blanchaer.
