TAPIR Seminar

Self-Force Waveforms with a Spinning Secondary
Josh Mathews, Graduate Student, Maths Support Centre, University College Dublin,
Speaker's Bio:
Currently in my fourth year of theoretical physics. I wasn't especially fond of maths up until studying at UCD and now most of my favourite modules have been ACM modules. I more than understand when students say they are not big fans of maths but having been there myself I know I can help. I specialise in ACM and physics modules and can offer help with Python and LaTex. Outside of academics you'll find me training in the university judo club or outdoors somewhere.

In this talk I will give a brief overview of the perturbative self-force approach to the relativistic two-body problem and the current effort to produce gravitational waveform templates for extreme mass ratio inspirals (EMRIs). I will specialise the discussion to the effect of the spin of the 'secondary' body on EMRI waveforms, including preliminary work on precessing spin configurations.  Beginning with simplified EMRI configurations, I will outline a practical first-principles approach to producing self-force waveforms and finish with some qualitative comparisons of subleading 'post-adiabatic' order waveforms with numerical relativity counterparts.
