Han worked with Professor Froney Crawford as a summer student investigating the modulation characteristics of PSR J0529-6652, a very luminous pulsar in the Large Magellanic Cloud that has shown unusual variability on short time-scales. This is a continuation of work that was first started by Dean Altemose ‘09. Han modified and extended some of Dean's analysis code to take a different approach toward characterizing the variability of this pulsar. The results are inconsistent with the predictions of a proposed model of pulsar emission and suggest that the model is incorrect or does not apply to emission from this pulsar.
Sam worked with Professor Etienne Gagnon on “Terahertz Pulse Shaping” Terahertz radiation is a form of light that is generated by a broad range of physical phenomena, including interaction of intense light pulses with semiconductor materials. While relatively easy to generate, using THz radiation can be difficult, due in part to our limited abilities at manipulating this form of light. Over the summer, Sam worked on a way to gain better control of the THz radiation by modifying the generation process. Specifically, he looked at using an etalon to shape the intense light pulse that would in turn shape the THz it generates. We were able to show that we can indeed control the spectral shape of the THz radiation and the work that Sam did will serve as foundation for further projects.
