J.S. Plaskett Medal

The Royal Astronomical Society of Canada and the Canadian Astronomical Society have established an award entitled The Plaskett Medal in recognition of the pivotal role played by John Stanley Plaskett in the establishment of astrophysical research in Canada. The award, consisting of a gold medal, is to be made annually to the Ph.D. graduate from a Canadian university who is judged to have submitted the most outstanding doctoral thesis in astronomy or astrophysics in the preceding two calendar years. The recipient is invited to address one or the other of the sponsoring Societies (at his or her choice) at their Annual Meeting, and to submit an invited article for the Journal of the Royal Astronomical Society of Canada (JRASC). The recipient will receive a $750 honorarium and all expenses to attend the meeting will be covered by that Society.

At most one candidate may be nominated by the head of his/her department from among the graduates of that university. The candidate need not have carried out his/her work in an astronomy or physics department, however, to be considered for the award, the candidate must be a CASCA member or must have been a CASCA member for at least one year during his/her doctoral studies.

For consideration for the 2015 award, the department head should send, in pdf format, the following materials to the chair of the awards committee:

  1. a letter of recommendation in support of the candidate/thesis (maximum three pages)
  2. a copy of the thesis
  3. a copy of the report from the outside examiner of the thesis

Copies of all materials should also be sent to the CASCA business office: casca at casca.ca. The deadline for submission is January 19, 2015. Note that if the thesis does not clearly indicate how much of its content represents the original work and ideas of the author, the department head should address this point in the letter. No other material should be submitted.

Note that the phrase “in the two preceding calendar years” in the eligibility rules makes it possible to re-nominate a candidate for whom an unsuccessful nomination was made in the preceding year. Because none of the documentation of previous nominations is retained for the use of the current selection committee, all re-nominations should be submitted with full documentation.

2014 Plaskett Medal

ponCASCA is pleased to announce that the recipient of the 2014 J.S. Plaskett Medal is Dr. Andrew Pon.

Dr. Pon completed his doctoral studies at the University of Victoria in 2013 under the supervision of Dr. Douglas Johnstone (UVic, NRC-Herzberg). His thesis, entitled “Shocks, Superbubbles, and Filaments: Investigations into Large Scale Gas Motions in Giant Molecular Clouds”, covers a wide range of topics in star formation — including gravitational collapse, turbulent heating, and Galactic ecology. This work bridges theory and observations, and crosses traditional boundaries between the detailed investigation of individual nearby star-forming regions and the much larger scale studies of galactic-scale star formation.

Dr. Pon is currently a postdoctoral researcher at the University of Leeds, where he is continuing his studies of turbulent dissipation and shock heating in molecular clouds.

CASCA congratulates Dr. Pon on the receipt of the 2014 J.S. Plaskett medal.
