Searching for Continuous Gravitational Waves

Main Focus

My work at AEI spans analytical source-modelling, numerical methods and algorithms, and observational astrophysics & astronomy as a member of the Einstein@Home Data Analysis team. On the analytical front, I work on modelling the interior dynamics of a glitching neutron star and analysing the continuous gravitational waves emission channels in this process [1]. In observational astrophysics & astronomy, I have run searches for high-frequency continuous gravitational waves in LIGO1-S5 data [2] using the Einstein@Home framework. Most recently, I have worked on the deepest low- and mid-frequency searches for continuous gravitational waves in the aLIGO-O1 and LIGO1-S6 data respectively [4,5,6] and designing novel algorithms for even deeper and cost-efficient searches [3]. In parallel, I am also interested in probing the early stages of the universe with radiation and matter, i.e. the Cosmic Microwave Background and the Large Scale Structure respectively [7].
