Mr. Omand’s thesis presents a model of the electromagnetic emissions of a pulsar winddriven nebula in the period following the death of the progenitor star. In particular, the
model is proposed as an emission mechanism for type I super-luminous supernovæ (SLSNI). The thesis computes the spectrum and time dependence in radio and millimetre bands
and makes predictions for observations to be carried out using the Jansky VLA and ALMA
observatories, respectively. VLA observations of 10 SLSNe-I remnants at 3GHz are presented
and compared to the model. 9 are null results, 1 shows a detection. The null results show
tensions with the model and are interpreted to mean that at least some of these sources
cannot be due to the proposed emission model. The model, the observations, and the
interpretation are all novel results. Examples of some results are shown in the future below,
which has been taken from Mr. Omand’s thesis

Altogether the work has been conducted in collaboration with a large number of other
researchers, for example those conducting the observations. Mr. Omand’s specific contributions have been identified in the thesis, and consent forms for publication of the work have
been obtained from all collaborators.
Following Mr. Omand’s revisions to the manuscript, which we requested and have reviewed, the committee recommends that a doctoral degree be awarded.
