Last Update: 8th November, 2016
The National Astronomical Observatory of Japan invites proposals at Atacama Submillimeter Telescope Experiment ASTE and with the Nobeyama 45-m telescope.
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 band are offered under the shared-risk basis. This opportunity is open to astronomers affiliated with institutes in Japan, Taiwan, and South Korea.
The Nobeyama 45-m telescope promotes ground-based observations at centimeter to millimeter wavelengths operated by the National Astronomical Observatory of Japan (NAOJ). In this call for observing proposals, single-beam spectroscopy or continuum observations in 20 - 116 GHz bands and four-beam spectroscopy observations in 80 - 116 GHz bands are offered. A new receiver Z45 in 42 - 46 GHz is offered under the shared-risk basis.
Following information is about observations with the 45-m telescope except for Joint Proposals.
For observation with the ASTE telescope, information can be obtained at Call for Proposals for the ASTE Telescope
2300 hours are expected to be available for open-use observations.
Astronomers and researchers in the related fields (including graduate students) can submit proposals.
In addition, undergraduate students, who are already admitted to graduate schools, can also submit proposals.
We only accept proposals written in English.
Since we open new categories and receiver, applicants are required to refer carefully to the instruction in this web page, Status Report, and A Guide for Preparation and Submission via Web.
|Category||Submission Deadline||Main Observing Period|
|Regular Program1||Thursday 1st December 2016 to Monday 15th May 2017|
|Joint Proposal for the Nobeyam 45-m Telescope and the ASTE Telescope|
Tuesday 13th December 2016, 15:00JST [06:00UT]
|March to April 2017|
|Director's Discretionary Time||Anytime after Submission Deadline for Regular Program3||Thursday 1st December 2016 to Monday 15th May 2017|
Important notice about the main differences from previous season is summarised as follows:
|New Observing Categories||Joint Proposal with the ASTE Telescope, Director's Discretionary Time, and Large Programs are open. Details of each proposal categories is described in Proposal Categories and Submission Deadline section in A Guide for Proposal Submission via Web page.|
|Receivers at 40 GHz||S40 receiver is decommissioned due to many spurs within its frequency range. The new single-pixel Z45 receiver with an RF frequency between 42 and 46 GHz is provided in a shared-risk mode. Applicants can also use H40 receiver as previous observing seasons.|
|Remote Observation||Experienced observers are allowed to perform remote observations in Japan (Not limited to the NAOJ Headquarter in Mitaka, Tokyo). Those who wish to perform remote observations should state in "Site" section in the Application Form and read carefully instructions summarised in Remote Observation. No compensation of observing time will be made even when your observing time is lost due to a trouble, bad weather, or any cases.|
|Spectral Window Mode||Spectral window mode that enables more flexible frequency resolution setting opens for FOREST observations.|
|Proprietary Period||By default, data obtained as part of an the Nobeyama 45-m science program are subject to a proprietary period of 18 months starting when all the observations of each project are complete.|
|Time Estimator||The time estimator is updated: time estimation with obtaining two polarizations and an imporovement of estimation with more realistic system temperature based on measurments of atmospheric opacity.|
|Change Request||Major change requests are defined as 1) adding new sources, 2) changing observing lines, and 3) changing mapping areas from the original proposals. Change requests are made through the Helpdesk. After a contact to the Helpdesk, an observer must submit a paper in which reasons is described within 1 page of A4. The paper must include a very clear description of the proposed change along with a clear, substantive justification for the change. The requests will be evaluated by the Time Allocation Committee (TAC) chair and the observatory director and will be approved only if they are fully justified. Change requests duplicating against current NRO proposals will not be approved.|
|There are special notices for the short program:
1. The observatory offers total observing time of about 200 hours, each LST time of about 8 hours for the Short Program.
2. Remote observation for the Short Program is only allowed from NAOJ Mitaka Campus.
3. Applicants must calculate their observing time with the value for the 2nd period in the time estimator.
(i.e., For Position switching observations: Scan number for one ON-point_p2, Tsys_obs_p2, and Total obs. time_p2. For On-The-Fly Observations: Tsys_obs_p2 and dTa*_p2.)
|The observatory encourages applicants to study based on observations with the 45-m telescope and the ASTE Telescope and/or the James Clerk Maxwell Telescope (JCMT).|
|Helpdesk||NRO offers Helpdesk support. Requests and questions about the open use of the Nobeyama 45-m telescope can be available through the Helpdesk. A trigger of Target of Opportunity observations should be sent to the Helpdesk.|
|Web Submission||From 2015--2016 observing season, we accept the proposal only via web submission form. If you face any difficulty in web submission, please contact us through the Helpdesk.|
|Support for New Users||The NRO staff offers support for observers who are not familiar with observations using the Nobeyama 45-m telescope. We provide support from help getting started to full collaboration. Please contact us via the Helpdesk for questions on proposal preparation, observing techniques and strategies, observation scripts, and data analysis.|
|ToO Observation||Please note that you should submit a proposal for the Regular Program or the short program for studies of expected ToO (Target of Opportunity) objects such as comets, gamma ray bursts, and extragalactic supernovae. The ToO trigger should be sent to the Helpdesk.|
|Target Duplication Check||Applicants are required to check their targets in the NRO 45-m legacy projects before submission. If the target objects have already been in list and target lines are as same as you desire, the reason why you need to be observed by yourselves must be described in Science Justification.|
|Observational Support for the Open Use||The assistant supports the open use observations, including remote observations. The assistant conducts the receiver tuning and the trouble shoot. In order to shorten communication time between users and the assistant, experienced users can tune the receiver by themselves.|
|Effect by Automotive Millimetre-Wave Radar||Automotive millimetre-wave radar mounted on the car may cause unwanted signals at 76-77 GHz. The observatory suggests users to avoid RF setting around 76--77 GHz if possible. Following links represent the results of test observations of receiving automotive millimetre-wave radar emitted from different types of cars: link1 link2|
|Re-allocation||Cancelled observing time due to unexpected instrumentation/telescope failure will be re-allocated. Observing time surrendered to back-up programs due to bad weather also will be compensated.|
|Travel Support||(1)The observatory will support travel expenses of domestic transportation for up to two observers per program is supported if you request financial support from the NAOJ. (2)If you come to NRO by train, the observatory offers transportation service from Nobeyama station to the observatory. Please describe the need of transportation service and your arrival time on On-line Submission of Observing Plan Sheet.|
|Visiting Instruments||The observatory allows to carry-in visiting instruments. If you are planning to carry-in a new instrument such as a receiver, you are requested to submit a PI instrument proposal to the obseratory. The procedure can be asked through our Helpdesk. Especially, we strongly request the PI to contact the observatory via the Helpdesk about your plan before submitting a funding proposal|
Proposal Preparation Guide:
Proposal Submission Form
If your proposal is approved, PI (a delegate) needs to send an observing plan sheet. Observers who will visit NRO can make a reservation for lodging with the sheet. The observatory will support travel expenses for two domestic observers (two times in total for observations and data reduction).Instructions for Observers (written in English):
A computer account is necessary for your observations. Information of the account will be sent to the principal investigator (or the contact person).
