Math-Physics Speaker Series Instalment 4

This evening, on Monday, November 29, Dr. P.T. Jayachandran joined us to present his talk titled, "Monitoring the Arctic Ionosphere – Research and Applications". Dr. Jayachandran is a physics professor at UNB and the Principal Investigator of the Canadian High Arctic Ionospheric Network (CHAIN). We were pleased to have him as our last speaker of the Fall term.

Maggie Lawrence, a fourth year physics student at UNB, wrote the following summary for his talk.

“Dr. Jayachandran spoke about physics research done at UNB in the Arctic ionosphere, and its numerous applications to our everyday life. First, Dr. Jayachandran explained how solar radiation and charged particles reach us here on Earth, starting with when they are emitted from the Sun, directed into the Earth along our magnetic field axes in the magnetosphere, and finally sent into the ionosphere. We learned about how auroras are like “nature’s TV” as Dr. Jayachandran drew analogies between the interactions of solar wind and the Earth’s upper atmosphere to create the well-known Northern Lights and old CRT televisions, but also learned how the same interactions that cause auroras disrupt technologies such as GPS and radio communications that we rely on every day. Dr. Jayachandran then went on to outline reasons his lab’s research in the Canadian Arctic is important, and talked about future plans to install radio instruments all over the Canadian north to further aid this work. Finally, the talk ended with some first-hand experience of what it is like to work as far north as Eureka, Nunavut, concluding a highly educational and captivating presentation on some of the sophisticated research done at UNB. Those interested in learning more about the work done by Dr. Jayachandran’s group and to see data collected in real time by their radio instruments should visit”

We are excited to continue on with our speaker series next term. Until then!
