An innovative astronomical spectrograph has achieved “first light”, the start of its life as a scientific tool for studying objects such as colliding galaxies, stellar nurseries and the remnants of exploded stars.

Spectrographs are instruments which spread out light according to wavelength, just as a prism spreads out a beam of sunlight into a “rainbow” of its constituent colours. The spectra created by the spectrograph reveals detailed information about the light source’s composition, motion, age, and more.

In May, 2017, after years of development, fabrication and testing, a team of astronomers from the University of Toronto installed the Wide Integral-Field Infrared Spectrograph (WIFIS) on the 2.3-metre Bok Telescope at the Steward Observatory in Arizona.

“WIFIS has the largest field-of-view of any infrared spectrograph of its type,” says WIFIS Principal Investigator, Prof. Dae-Sik Moon, from the Department of Astronomy & Astrophysics, University of Toronto. “This makes WIFIS a unique instrument ideally suited for observing large objects.”

The Dunlap Institute is committed to sharing astronomical discovery with the public. Through lectures, the web, social and new media, an interactive planetarium, and major events like the Toronto Science Festival, we are helping to answer the public’s questions about the Universe.
Our work is greatly enhanced through collaborations with the Department of Astronomy & Astrophysics, Canadian Institute for Theoretical Astrophysics, David Dunlap Observatory, Ontario Science Centre, Royal Astronomical Society of Canada, the Toronto Public Library, and many other partners.
