Researching Radio Astronomy Affiliated Curtin Appointed 2022
Callan is a PhD student at the Curtin Institute of Radio Astronomy (CIRA), which is the Curtin node of the International Centre for Radio Astronomy Research (ICRAR), researching relativistic jets launched from stellar-mass black holes within our Galaxy. Prior to commencing his PhD in 2022, Callan studied a Bachelor of Advanced Science (with Honours) at Curtin University, majoring in Physics recently graduating in 2021.
Callans research is focused on investigating new imaging and modelling techniques to analyse observations made by radio telescopes of jets launched from black holes within our Galaxy. These jets can travel across the resolution of an image in a matter of minutes, making hours long observations difficult to reconstruct, since the jets become smeared out (imaging trying to take a long exposure photo of a speeding car). Through the use of new imaging and modelling techniques, we hope to be able to improve our reconstructions of these observations, which when combined with X-ray observations, will help us answer the question, ‘how are these jets launched?’.
