Proposals for CFHT Open for Semester 2024B

The 3.6 meter optical/infrared Canadian-France-Hawaii Telescope (CFHT) is now open for proposals from all Taiwan-based researchers for semester 2024B. The deadline for proposal submission is:

2024 March 21st at 23:59 Taiwan time

We expect up to 2.5 nights to be allocated, depending on demand and quality of proposals. Available instruments for 2024B are MegaCam, WIRCam, ESPaDOnS, Sitelle, and SPIRou (some targets are reserved for the SPIRou Legacy Survey and cannot be accessed by other programs with the same science as the SLS). Detailed information on the telescope, available instrumentation, proposal format, and how to submit proposals is available from the CFHT web page:

Eligibility

All professional astronomers affiliated with Taiwanese academic institutes are eligible to apply for observing time.

  • Postdocs or faculty who will soon (e.g., within the same semester as the CfP) join a Taiwanese institute could also submit proposals as a PI.
  • For visiting scholars of ASIAA who are not physically based at ASIAA: their proposals have to be PI'd by researchers who are physicallybased in ASIAA or other institutes in Taiwan.

Long-Term Proposals

A category of "long-term proposals" was created in 2014A for CFHT-Taiwan proposals. Proposals requesting for multi-semester observations or large amount of observing time should follow the guideline.

Exploratory Programs

To encourage innovative science, we will continue considering "exploratory" programs using MegaCam, WIRCam, Sitelle, or ESPaDOnS that require no more than 1 hour of observing time. Such proposals will not be refereed, but will be scrutinized by the TAC and allocated time based on scientific merit and feasibility. When submitting such proposals, please state at the beginning of the scientific justification that "This is an EXPLORATORY proposal".

Queued Service Observations Snapshot Programs

In addition, we would like to bring to your attention to the Queued Service (QSO) snapshot program. These are programs that can be executed with either MegaCam or WIRCam in relatively poor seeing conditions when the seeing is >1.2". Projects executed under the QSO snapshot program are not charged to the available observing time for Taiwan. Proposals to the QSO snapshot program will not be refereed, but will be scrutinized by the TAC for scientific value and feasibility.

Resubmission due to Lost Time

If your scheduled project from previous semesters was not completed for any reason (including bad weather), you will need to resubmit your proposal explaining why you need more time. Your proposal will be stronger if the available data has been analyzed, and you use this data to demonstrate that the stated science goals can be achieved with allocation of the full requested time.

Time Allocation Process

All new proposals, and where deemed necessary resubmitted proposals, are refereed by researchers selected by the Taiwan-CFHT TAC based on their demonstrated expertise in the relevant research fields. Apart from the referees comments, who are asked to evaluate primarily the scientific strength of the proposal, the Taiwan-CFHT TAC also takes into account technical feasibility. For those who have previously been scheduled observing time on the CFHT, the Taiwan-CFHT TAC will also take into account the status of previously executed projects and publications.
