Semester 2017A Call for Proposals

Gemini Observatory invites its community to propose scientific investigations for the 2017A semester, 1 February 2017 - 31 July 2017.

The submission deadline varies with participant. Joint proposals should be submitted by the deadline of the participant country to which the Principal Investigator is affiliated. Proposals for exchange time on Gemini from the Subaru community are required to be submitted by September 30, 2016 at 23:59 HST (Hawaii-Aleutian Standard Time). An overview of the Gemini proposal submission process is available.

The Call is open to all participants and host institutions : Argentina, Brazil, Canada, the United States, Chile, the University of Hawaii, Korea (under its Limited-term Collaboration MoU), and Australia (under its Limited-term Collaboration MoU). US time is open to all astronomers worldwide including those at non-US institutions, although in that case the proposal must explain why U.S. national facilities are needed. The distribution of time across the participants is available in the time distribution table.

    Summary of 2017A Gemini Capabilities

     

    Gemini North

    Gemini North will not be available from Monday July 10 2017 to the end of the semester, for work on the dome. Targets will be limited to 4 < RA hours < 23.5.

    Gemini North will have dome shutter restrictions in place through 2017A. Gemini North PIs with targets with declinations below -35° and above +78° should have alternative targets available.

    In some cases there are additional constraints as described below and in the target and instrument accessibility page.


    Facility instruments offered in 2017A, in queue or classical mode, are:
    Visitor instruments offered in 2017A (subject to demand), in queue mode only, are:
    • TEXES: a high resolution (R ~4,000-100,000) mid-infrared (5-25 micron) spectrometer. Available during February 2017. Targets are generally limited to 4h < RA < 20h.
    • DSSI Speckle camera: a dual-channel visual-wavelength camera giving simultaneous diffraction limited images in two filters over a 2.8 arcsec field of view. Available during the first half of 2017A. Targets are generally limited to 4h < RA < 20h (targets near the RA limits are available only for short periods). The scheduling and length of the entire DSSI visitor block(s) will be subject to community demand and instrument availability.
    • GRACES: a high-resolution, R~67,500, optical (0.4-1 micron) spectrometer. Scheduled blocks to be determined with CFHT, based on demand.

     

    Gemini South

    Targets are generally limited to 5 < RA hours < 2 and -90 < dec degrees < +28. In some cases there are additional constraints as described below and in the target and instrument accessibility page.
    Facility instruments offered in 2017A, in queue or classical mode, are:
    Visitor instruments offered in 2017A (subject to demand), in queue mode only, are:
    • DSSI Speckle camera: a dual-channel visual-wavelength camera giving simultaneous diffraction limited images in two filters over a 2.8 arcsec field of view. Available during the second half of 2017A. Targets are generally limited to 12h < RA < 1h. The scheduling and length of the entire DSSI visitor block(s) will be subject to community demand and instrument availability.
    • Phoenix: A high-resolution (R ~50,000 - 80,000), near IR (1-5 micron) echelle spectrometer. Available during the second half of 2017A. Targets are generally limited to 12h < RA < 1h. The scheduling and length of the Phoenix visitor block(s) will be subject to community demand and instrument availability. An ITC is available on the NOAO Phoenix webpage.

     


     

    Important Dates for 2017A

    The deadline for Phase I submission varies with participant. For successful proposals, both queue and classical, the Phase II submission deadline is 17 January, 2017. More information is available in the 2017A schedule.


     


     

    Phase I Submission Guidelines for 2017A

    Proposals for time on Gemini, and for time on Subaru via the Gemini-Subaru exchange program, must use the Gemini Phase I Tool (PIT). Latex and Word templates are available to create a pdf attachment which includes the science and technical cases. See the PIT page for installation information and the help pages for the PIT for assistance. The requested time for the visitor instruments should include all required calibrations (unlike the facility instruments where the time required for a specified set of baseline calibrations should not be included). Investigators are requested to include the output from the integration time calculators in the proposal.


     


     

    Time Available in 2017A

    The time available for each participant and host institution in 2017A is shown on the time distribution page. At Gemini North, ~150 nights are expected to be available for science. At Gemini South, ~165 nights are expected to be available for science.

     


     

    Limited-Term Collaborations

    Proposals from Korea and Australia are accepted under Limited-Term Collaborations with Gemini Observatory. Proposals with PIs from limited-term collaborations are not eligible for joint proposals or Subaru Exchange time. Additionally, for PIs from limited-term collaborations, access to block-scheduled instruments is subject to scheduling constraints, and not guaranteed, irrespective of science rank. The block-scheduled instruments are GeMS/GSAOI, GRACES, DSSI, and Phoenix.

     


     

    Subaru Exchange Time

    The exchange of time between the Gemini and Subaru communities will continue in 2017A. Gemini expects to be able to exchange a minimum of 5 nights in semester 2017A.
  • Limited-term collaborators (Korea and Australia) are not eligible for the exchange program.
  • Proposals should be submitted via the normal Gemini Phase I process. PIs in the Gemini community who intend to use the Subaru telescope are encouraged to apply through the time-exchange program and not through the open use Subaru Call.
  • Subaru time must be requested in integer nights, and runs will be evenly distributed across dark, gray and bright nights.
  • Due to repair work of the mirror hatch, the Subaru telescope will be unavailable for several nights in 2017A. The exact schedule has not been fixed yet.
  • Nearly all dark nights will be allocated to HSC in 2017A, and will not be available to other instruments
  • The Suprime-Cam is offered for open-use for the last time in 2017A.
  • See the Subaru Call for Proposals for important information. Notes on capabilities follow:

    Priority Visitor Observing Mode

    In Priority Visitor Observing, a visiting observer comes to the Observatory for a block exceeding their program's time allocation, and elects when to carry out their program within that block. This may be when conditions are within their requirement, better than their requirement or even fail to meet their requirement. If time remains on the program after the summit time is complete, the program carries on in the regular queue with priority given by the TAC-assigned science ranking band. PV observing mode is offered as a possibility for band 1 queue programs in 2017A. Investigators wishing to have their program considered for PV observing should indicate that in the Technical Design portion of their 2017A queue proposal.

     

     


     

    Other Proposal Opportunities in 2017A

    Other proposal opportunities are available at Gemini Observatory in 2017A. These include:

    • The Fast Turnaround (FT) Program provides monthly opportunities to submit proposals, with successful programs scheduled for observation starting one month after each proposal deadline. Up to 10% of the time at Gemini North and Gemini South is available for the FT program.
    • Director's Discretionary Time is open to any astronomer worldwide and can be submitted at any time.
    • Poor Weather Proposals are solicited for programs that can use poor, but usable, conditions and are executed when nothing in the regular queue is observable. Proposals can be submitted via the normal TAC process (this call) or at any time.

     

     


     

    Bring One, Get One: Travel Assistance Program

    The Gemini Observatory, at the request of its Users' Committee, would like to strongly encourage the visit of students, and other early-career observers, to observing runs (attending Queue, Classical, or Priority Visiting Observing). In semester 2017A, the Gemini Observatory may subsidize with up to US$2000 the travel expenses of individual under- and graduate students, and other early career observers, visiting Gemini North or South, when accompanying a senior observer. The "Bring One, Get One" Student Observer Support Program" page has full details on this program. This program is subject to the availability of limited funds.


     


     

    Remote Eavesdropping

    Remote Eavesdropping will be available in 2017A for all queue programs. Investigators will be invited to sign up for eavesdropping via the PI email announcing they have been granted time.
