Research

I am interested in constraining very light Axion-Like Particles (ALPs) using the X-Ray transparency of galaxy clusters. So far, I have been working in constraining very light ALPs using Chandra High Energy Transmission Grating spectroscopy of the powerful cluster-hosted quasar H1821+643. In the long term, I will focus on testing the sensitivity of the Athena X-Ray Observatory, expected to be launched in 2034, to constraining these very light ALPs.
