The Thirty Meter Telescope (TMT) is one of the extremely large telescopes ( that will allow us to see deeper into space and observe cosmic objects with unprecedented sensitivity. The TMT will have three times bigger aperture than currently existing largest visible-light telescopes in the world. The new cutting-edge technology and adaptive optics technique enable TMT to provide unparalleled spatial resolution with images more than 12 times sharper than those from the Hubble Space Telescope. It will provide new observational opportunities in the field of astronomy and astrophysics with various instruments from ultraviolet to mid-infrared. This unique facility will allow astronomers to address fundamental questions in astronomy ranging from understanding planets and star formation to unraveling history of galaxies and large-scale structure in the Universe.

This workshop will mainly be focused on the ongoing development of the first and second generation instruments. Wide Field Optical Spectrometer (WFOS) and Infrared Imaging Spectrometer (IRIS) are leading among proposed first generation instruments. WFOS is being developed as a first light instrument with aim to provide near-ultraviolet to optical (0.3 – 1.0 μm) spectroscopy with spectral resolution of ~3500 - 5000 over a more than 25 square arcmin field-of-view. The IRIS will be the first generation near-infrared instrument with wavelength coverage of 0.84 - 2.4 μm and is being designed to sample the diffraction limit of the TMT. IRIS will include an integral field spectrograph with spectral resolution more than 4000 and imaging camera with a field of view of 34x34 square arcsec. Several second generation instruments are also proposed for the TMT including Multi-fiber High-resolution NIR spectometer (MODHIS), High-Resolution Optical Spectrometer (HROS), and Planetary System Instrument (PSI). These second generation instruments will have capabilities to do high resolution spectroscopy from optical to IR wavelengths.

Under this proposed national workshop at ARIRS Nainital, Indian astronomical community looks forward to explore and discuss about possibilities to play major role towards one of the back-end instruments. I-TMT has already taken many steps towards manufacturing of the telescope itself ( During the workshop, we also plan to have a brief overview about the progress made towards ongoing work-packages for the TMT and to discuss about possible science cases in a larger interest of Indian astronomers. In this workshop, early-stage researchers/Ph.D. students/Post-docs are encouraged for their active participation to build a technical know-how of this ongoing mega-science project as a part of the human resource development for the coming decade.
