Integral-Field Spectrograph

Giant Magellan Telescope Integral-Field Spectrograph (GMTIFS)
The Integral-Field Spectrograph will provide a quantum leap in high spatial resolution spectroscopy. It will target the physics of galaxy assembly and the complex molecular soup of galaxy evolution, including blackholes and the reionization of the universe. The Integral-Field Spectrograph is a diffraction-limited imager operating across the YJHK bands. It will be the third scientific instrument installed on the Giant Magellan Telescope and will be the telescope’s first Adaptive Optics instrument.


The GMTIFS is being developed by astronomer Rob Sharp from the Australian National University

Science Goals

  • Young stars: star and planet formation processes
  • Nearby galaxies: cahemical enrichment history
  • First galaxies: structure and assembly
  • Massive black holes: masses and physics of galaxy nuclei
  • Gamma ray bursts: intergalactic medium at z~7
