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 in good standing or must have been a CASCA member in good standing for at least two years during his/her doctoral studies.

For consideration for the 2017 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
  4. (optional) a letter from the outside examiner in the case that the report is insufficiently detailed

Copies of all materials should also be sent to the CASCA business office: casca at casca.ca. The deadline for submission is Nov 21 2016. 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.

2017 Plaskett Medal

Rajabi

CASCA is pleased to announce Dr. Fereshteh Rajabi as the 2017 recipient of the J. S. Plaskett Medal.

Dr. Rajabi completed her doctoral studies at the University of Western Ontario under the supervision of Dr. Martin Houde. Her thesis entitled “Dicke’s Superradiance in Astrophysics” extends the mathematical description of this intriguing physical process to many phenomena of astrophysical interest. Superradiance is a quantum mechanical and coherent behaviour between closely spaced atoms or molecules (i.e., several within a wavelength) that makes them, when certain conditions are met, emit radiation that is much more focused and intense than expected. Dr. Rajabi used superradiance to elegantly explain anomalous fluxes in the 21cm line of hydrogen atom and unexplained maser flares and bursts in the envelopes of evolved stars. She made fundamental physical advances that brought superradiance out of the lab and into an ever more surprising Universe. Her work has attracted worldwide attention not only in astrophysics, but also in the field of quantum optics.

CASCA congratulates Dr. Rajabi on the receipt of the 2017 Plaskett medal for her highly original work to advance our understanding of fascinating transient phenomena in the Universe.
