LRP2020 is the third in the series of Canadian Long Range Plans for astronomy and astrophysics. LRP2020 will review the field of astronomy and astrophysics, along with associated education, training, and outreach programs, and will produce a list of recommended priorities for the next decade. The resulting plan will serve as a single unified vision for the highest priority projects in astronomy in Canada over the period 2020 to 2030.

Criteria for LRP White papers

Assessment and prioritisation of facilities and programs in LRP2020 will be based on a predefined set of criteria:

  1. How does the proposed initiative result in fundamental or transformational advances in our understanding of the Universe?
  2. What are the main scientific risks and how will they be mitigated?
  3. Is there the expectation of and capacity for Canadian scientific, technical or strategic leadership?
  4. Is there support from, involvement from, and coordination within the relevant Canadian community and more broadly?
  5. Will this program position Canadian astronomy for future opportunities and returns in 2020-2030 or beyond 2030?
  6. In what ways is the cost-benefit ratio, including existing investments and future operating costs, favourable?
  7. What are the main programmatic risks and how will they be mitigated?
  8. Does the proposed initiative offer specific tangible benefits to Canadians, including but not limited to interdisciplinary research, industry opportunities, HQP training, EDI, outreach or education?

In addition, the following overall criterion will be applied to the final ensemble of prioritisations and recommendations:

9. The sum of the recommendations will be for a set of facilities and programs that reflects Canada’s strengths and breadth, with a range of project sizes, time scales, science areas and degrees of Canadian participation, offering strong prospects for Canadian HQP training, and providing specific tangible benefits to Canadians. Where appropriate and feasible, the recommendations will be aligned with the priorities of government and funding agencies and with the recommendations of previous Long Range Plans.
