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.  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 2018A and 2018B.  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
    • 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.  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:

  • PHOENIX
    • A high-resolution (R ~50,000 - 80,000), near IR (1-5 micron) echelle spectrometer.  PHOENIX is available in 2018B.  Questions may be directed to gemini-vip (at) gemini.edu.
  • 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.  The Gemini contact scientist for DSSI 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 available in 2018A, and plans to return in the future, timing to be decided.  The Gemini contact scientist for IGRINS is Hwihyun Kim, and questions may also be directed to gemini-vip (at) gemini.edu.
  • 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.  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
