Thirty Meter Telescope Science Forum 2017

November 7, 2017 - November 9, 2017

Supporting Workshops


Three worshops are organized before/after the TMT Forum 2017, on high-resolution spectroscopy, high-contrast exoplanet imaging, and a special workshop about the first-generation science instrument WFOS.


Please, email the contact person listed below for each workshop in case you would like to attend any of these supporting meetings.



  • PSI (Planetary System Imager) workshop:
  • Date: November 06
  • Location: Mysore, Infosys campus (same as TMT Science Forum)
  • Duration: 1 full day
  • Contact person: Ben Mazin (
  • Description: Preliminary work on the high contrast exoplanet instrument for TMT, currently called the Planetary System Imager (PSI), has started in 2015 and a large group of scientists from around the TMT consortium has been assembled to look in detail at the science and technical issues surrounding PSI. The technical team includes significant participation from US, Canadian, and Japanese partners.  

This workshop will be an opportunity to engage scientists from across the entire TMT collaboration to discuss scientific issues (morning session), and instrumentation issues (afternoon session).  The workshop is open to anyone wishing to participate on either the scientific or technical sides of PSI.



  • High-resolution spectroscopy with TMT - A science and instrument workshop:
  • Date: November 06
  • Location: Mysore, Infosys campus (same as TMT Science Forum)
  • Duration: 1 full day
  • Contact person: Sivarani Thirupathi (
  • Description: High resolution spectrograph (Optical/NIR) for TMT is a powerful instrument showcasing high sensitivity (from a large aperture) and recent progress in adaptive optics.  High resolution spectroscopy is useful for studies like those of exoplanet atmospheres, chemical/kinematical history of Milky-way and the resolved stellar populations in the local volume of  galaxies, ISM and IGM studies.  The work horse  nature of optical and NIR high resolution spectrographs in catering to a wide range of science cases and a large user community among the TMT partnership makes it an ideal 2nd generation instrument. Despite the tremendous interest in high resolution spectroscopy, there have been no focussed teams working towards the building of a high resolution spectrograph.
    This workshop aims  to bring the science and instrument teams across the partnership together to  form a working group that will collaborate and engage in building the TMT-HRS. The discussions will help prioritise key science areas and the technical specifications for these complex  instruments.  
    The topics of the workshop will include discussions on the following science areas and  examples of required performance,  signal to noise and exposure times for some key science cases:
    • Stellar and ISM abundances of resolved stellar populations in Milky-way and the neighbourhood
    • Stellar kinematics , cluster dynamics, stellar rotation and pulsations
    • Detection of exoplanet atmospheres
    • IGM studies
    • Key instrument concepts for Optical and NIR high resolution spectrographs
    • Stability requirements for the studies variations of fundamental constants and for the exoplanet detection of earth like and earth analogs.

We also propose to have dedicated discussion sessions on the key instrument requirements, e.g. the efficiencies across wavelengths, spectral resolution, stability, prioritising optical/NIR wavelengths and requirements on scalability/flexibility for AO/multiplexing/IFU, based on the potential science cases.  We also propose to review, new technologies that TMT-HRS can advantage of being a 2nd generation instrument.



  • WFOS (Wide-Field Optical Spectrometer) Science Workshop (**changes in date & location**)
  • Date: November 06
  • Location: Mysore, Infosys Campus (same as TMT Science Forum)
  • Duration: 1/2 day, afternoon session only
  • Contact person: Kevin Bundy (
  • Description: The goal of this workshop is to bring together TMT scientists from all partner countries who are interested in the capabilities and scientific potential of WFOS.  We will present the status and prospects of the instrument design and hear how recent advances in high-redshift galaxy studies, local group stellar population analyses, resolved galaxy spectroscopy at z < 1, and transient followup motivate and drive requirements for the exciting science programs that WFOS will make possible.

[Note that this WFOS Science Workshop will be complemented by a technical WFOS team meeting in Bangalore, planned for November 4+5. Anyone outside the currently-engaged technical team members is welcome to attend - contact Kevin Bundy at the above email]. 



  • The b-MICHI (mid-IR) workshop has been canceled.

    Note from Chris Packham: "To avoid clashing with the other two workshops scheduled on November 06, and as several MICHI workshops had already been held in the past, we have chosen to hold a MICHI group-meeting within the Science Forum, during the instrumentation breakout sessions.  This will ensure those persons interested in the high-contrast exoplanet and/or high spectral resolution workshops to attend those two workshops, and hopefully the MICHI breakout session as well.  Note that we plan to present the MICHI instrument concept in both the high-contrast exoplanet and high spectral resolution workshops."
