Visiting Instruments at Gemini

Gemini North:

  • TEXES
    • TEXES, the Texas Echelon Cross Echelle Spectrograph is a high resolution (R ~ 4,000-100,000) mid-infrared (4.5-25 micron) spectrometer.  TEXES is not available in 2020.
  • 'ALOPEKE
    • 'Alopeke (Hawaiian for "fox") is a fast low-noise dual-channel and dual-plate-scale imager based on the Differential Speckle Survey Instrument.  This is permanently mounted on the calibration port at Gemini North.  The Gemini contact scientist for 'Alopeke is Andrew Stephens, and questions may also be directed to gemini-vip (at) gemini.edu.
  • POLISH2
    • POLISH2 is a high-precision polarimeter aimed at exoplanet reflection polarimetry.  POLISH2 is available for 2020B.  Questions about POLISH2 observing should be directed to Sloane Wiktorowicz (sloane.j.wiktorowicz (at) aero.org)
  • HIPPI-2
    • HIPPI-2 is a high-precision polarimeter designed to capture the polarization signatures of exoplanets.  HIPPI-2 is not available yet.
  • MAROON-X   Future instrument!
    • MAROON-X is a fiber-fed, red-optical, high-precision radial-velocity spectrograph expected to have the capability to detect Earth-size planets in the habitable zones of mid- to late-M dwarfs using the radial velocity method.  MAROON-X  has been delivered to Gemini and is undergoing commissioning.  The Gemini contact scientist for MAROON-X will be Siyi Xu, and the PI is Jacob Bean.  Questions may also be directed to gemini-vip (at) gemini.edu

Gemini South:

  • Zorro
    • Zorro (Spanish for "fox") is a fast low-noise dual-channel and dual-plate-scale imager based on the Differential Speckle Survey Instrument (DSSI).  It is permanently mounted on the calibration port at Gemini South. The Gemini contact scientist for Zorro is Ricardo Salinas, and questions may also be directed to gemini-vip (at) gemini.edu.
  • IGRINS
    • A high-resolution (R~45,000), single-setting, near IR (1.45 - 2.5 microns) echelle spectrometer.  IGRINS is expected to be available from 2020A until ~2022B.  The Gemini contact scientist for IGRINS is Hwihyun Kim, and questions may also be directed to gemini-vip (at) gemini.edu.
  • GIRMOS  Future instrument!
    • GIRMOS is intended to provide Gemini with high performance multi-object adaptive optics, with the ability to carry out simultaneous high angular resolution, spatially resolved infrared spectroscopy of four objects within a two arcminute field of regard.  GIRMOS is still in the planning stages and it expected to be available in 2024.  The Gemini Project Scientist for GIRMOS is Marie Lemoine-Busserolle, and the PI is Suresh Sivanandam.  Questions may also be directed to gemini-vip (at) gemini.edu

Retired Visiting Instruments:

  • PHOENIX
    • A high-resolution (R ~50,000 - 80,000), near IR (1-5 micron) echelle spectrometer.    Phoenix was in frequent use at Gemini South until 2019, and publications using Phoenix can be searched here.
