The National Astronomical Observatory of Japan invites proposals at the Atacama Submillimeter Telescope Experiment (ASTE)

The Atacama Submillimeter Telescope Experiment (ASTE) is a project to promote ground-based observations at submillimeter wavelengths with a telescope in Atacama desert in Chile, operated by the National Astronomical Observatory of Japan (NAOJ), under the collaboration with University of Chile and Japanese Universities including University of Tokyo, Osaka Prefecture University, Ibaraki University, Hokkaido University, Keio University, and Joetsu University of Education. Single-beam spectroscopy observations in 350 GHz and 460 GHz bands are offered under the shared-risk basis. This opportunity is open to astronomers affiliated with institutes in Japan, Taiwan, and South Korea.

Seiichi Sakamoto
Director, Chile Observatory, National Astronomical Observatory of Japan

Available observing mode:

Single-beam spectroscopy observations in 350GHz-band (DASH345) and ASTE Band 8 with both the spectrometers (MAC/WHSF) are offered for open-use proposals. Details of the receiver and the spectrometers are available on the instrumentation web page.

Scheduling period:

June 1st to September 30th, 2017

Total observing time:

~300 hours between 21 - 6h in LST

Available time is roughly 30h for LST=21-22h, 49h for LST=22-23h, 57h for LST=23-24, 47h for LST=0-1h, 40h for LST=1-2h, 33h for LST=2-3h, 23h for LST=3-4h, 22h for LST=4-5h, and 11h for LST=5-6h

Submission deadline:

May 9, 2017 (15:00 JST or 6:00 UT)

Instruction and related information for observers:

Please visit the URL below to find instruction for proposal preparation and submission, updated reports on status of the telescope and instruments, and related information for observers.

Proposal Template:

Proposers must use this template (LaTeX) for the science and technical justifications. No other formats are accepted. The scientific and technical justification, including figures, tables and references, must fit within 3 pages. The cover-page is generated online through the "Proposal Submission" page.

Proposal Categories:

  1. General
    2. This is the regular observing proposal, and the proposals can be submitted here. We encourage large scale projects that can lead to outcome with significant impact.
  2. Joint observations with the 45m telescope
    3. Joint projects are not offered for this call for proposals.
  3. Guaranteed Time Observations
    4. GTO is not offered for this call for proposals.
  4. Directors Discretionary Time (DDT)
    5. DDT is not offered for this call for proposals.

Proposal Rules:

  • Proposal must be written in English.
  • Proposal must be prepared as a PDF file describing the scientific backgrounds, goals, plan/strategy of observations, estimation of observing time and related information.
  • Proposals must be submitted through the online submission form, which is accessible from the "Proposal Submission" page. We do not accept proposal resubmission before and after the proposal deadline unless it is properly justified.

Proposal Evaluation:

The proposals are evaluated by the mm/submm Time Allocation Committee of the NAOJ, and the final time allocation is also made at the Time Allocation Committee. It is advised that the proposers clearly state the science value, uniqueness, and originality.

Observations:

PI/co-Is are expected to conduct their observations by themselves at Mitaka, headquarters of NAOJ in Tokyo, Japan for observational support. Experienced users can operate the telescope from their home institute. No compensation of observing time will be made even when your observing time is lost due to a trouble, bad weather, or any cases. The travel cost of domestic transportation for up to two observers per program is supported if you request financial support from the NAOJ.

ASTE data delivery:

The full-size ASTE science data will be provided to the PIs via a FTP server in the NAOJ Chile observatory within 1.5 months after their final observations.

Policy for data release:

From 2013 term, all ASTE raw data will be released after 1.5 years from the completion of the data delivery via the NAOJ archive. In addition, all ASTE data reduced by PI have to be submitted to the NAOJ Chile Observatory within 1.5 years after the completion of the data delivery. These ASTE data will be available for anonymous download from the NAOJ archive. In the case that a PI refuses to submit the reduced data, the NAOJ Chile Observatory will possibly reject a new ASTE proposal from the PI.

Duplication rules:

In ASTE, a duplication is defined as an observation of a same target, frequency and sensitivity. If a proposal duplicates others, only the highest ranked proposal will be allocated.

Guaranteed Time Observations: (not offered for this call)

The ASTE operation members can apply for Guaranteed Time Observations (GTO). The deadline for submission is the same as that for common-use proposals. If a GTO proposal duplicate a common-use proposal, the above “Duplication rules” is also applicable to this case.
