Subaru Intensive Program

1. Definition

The following proposals are regarded as Intensive Programs.
(i) Proposals which request more than 5 nights for the classical mode and 3.5 nights for the HSC queue mode in a semester.
(ii) Proposals which request observing nights up to 40 nights for the classical mode and 28 nights for the HSC queue mode over up to 6 consecutive semesters.
The maximum number of nights in a semester is 20 nights for the classical mode and 14 nights for the HSC Queue mode.
* Please note that the number of nights available for the open-use observations is expected to be relatively small due to pressures by SSP and carried-over intensive observations.

2. Eligibility

Only Japanese researchers (i.e., either researchers of Japanese nationality or those belonging to Japanese institutes) can be the PIs of Intensive Program proposals.

3. Available Instruments for Intensive Program

Facility Instruments

Visiting Instruments/Devices

For intensive programs with a visiting instrument/device, the Time Allocation Committee and the observatory will assess its technical feasibility in a more cautious manner than those for the facility instruments. The observatory may request the instrument group to provide additional information as described in 'General Review Points for Technical Justification of Intensive Program with Visiting Instrument'. Thus, consultation with the instrument group before submitting proposals is essential. Currently the following instruments/devices may be available:

Important note on Intensive Proposals using time exchange

Intensive programs using Gemini instruments can be submitted only for B semesters (March deadline). Intensive proposals requesting Keck instruments are not allowed.

4. Notice for Intensive Program Applicants

Dupulication Unallowed
Identical or very similar proposals should not be submitted to both Normal and Intensive Programs.
Scientific Justification
The maximum page limit of scientific justification is 5 pages. It is desirable to clarify the following points in the Scientific Justification:
  • Uniqueness
  • Impact to broad astronomical community
  • Comparison with similar (firmly planned or ongoing) programs by other large telescopes
  • Outline of the schedule to complete the program
[NOTE] Roles of Co-Investigators should be described in "Team Expertise" section in Coversheet.

5. Oral Interview

In addition to the proposal screening by referees, the PI may be asked to be interviewed at the Time Allocation Committee (TAC) meeting. This interview is a short presentation followed by questions from the committee members, conducted via remote-connection. The relevant PIs of Intensive Program proposals (or alternative persons selected from CoIs in case of unavoidable circumstances) are obliged to attend this interview which is scheduled on the first day of TAC meeting.

6. Notice for Accepted Intensive PIs

Devotion and Complement
Since the PI of an accepted Intensive Program proposal should devote to it, it is not desirable that same person doubles as the PIs of Intensive program and Normal program proposals simultaneously. However, if the overall completion rate is expected to be significantly low, we allow submission of an equivalent normal program proposal (of the same science goal) by the same PI at the last semester of the running intensive program.
Report to TAC
The PIs of accepted Intensive Program proposals should report their observations and achievements to the Time Allocation Committee upon request, so that the Committee can check and assess them. The Time Allocation Committee will decide, at the time of acceptance, whether and when a mid term review for each program is necessary in order to judge whether the program may be continued or not.
Report in Users' Meeting
Reports of each accepted Intensive Program must be presented at the Subaru Users' Meeting.
