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 2018.
  • '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, and is available for 2018A and 2018B.
  • POLISH2
    • POLISH2 is a high-precision polarimeter aimed at exoplanet reflection polarimetry.  POLISH2 is available for 2018A and 2018B.
  • 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
    • 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 is expected to be delivered to Gemini toward the end of 2018, and to be available for use following commissioning and science verification.

Gemini South:

  • PHOENIX
    • A high-resolution (R ~50,000 - 80,000), near IR (1-5 micron) echelle spectrometer.  PHOENIX is available in 2018B.
  • DSSI
    • DSSI (Differential Speckle Survey Instrument) provides simultaneous diffraction-limited optical imaging (FWHM~0.02" at 650nm) of targets as faint as V~16-17, in 2 channels over a ~2.8 - 5.6 arcsecond field-of-view.  DSSI is available in 2018A and 2018B.
  • IGRINS
    • A high-resolution (R~45,000), single-setting, near IR (1.45 - 2.5 microns) echelle spectrometer.  IGRINS is available in 2018A.
  • GIRMOS
    • 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.
