Yvette Perrott


Yvette did her undergraduate studies at the University of Auckland, gaining a BA, BSc and BSc(Hons) majoring in Physics, Italian and Spanish before moving to Cambridge University on a Rutherford PhD Scholarship in 2010. She completed her PhD in the Cavendish Astrophysics Group in 2013 and was awarded a Trinity College Junior Research Fellowship in the same year. In 2017 she was awarded a Rutherford Discovery Fellowship which she took up at VUW in 2018.

Research Interests

My main research interest is the study of clusters of galaxies. Galaxy clusters contain hot gas which interacts with the leftover radiation from the Big Bang, producing a signal in the radio frequency range known as the Sunyaev-Zel'dovich (SZ) effect. My research involves observing the SZ signal with radio telescopes and using this to infer the total masses of galaxy clusters, which as a function of distance can be used to study the expansion history and properties of the Universe.
