SEMI-ANALYTIC MODELING

Semi-analytic Models (SAMs) try to boil down everything we know about the evolution of black holes and galaxies into a concise set of equations.  In the era of large cosmological simulations, these are still excellent tools when you need large effective volumes and small galaxies. 

 

I can also use my semi-analytic model to bridge astrophysics between event horizon scales to cosmological scales.  In the video to the right, you can see the evolution of black holes in a small galaxy cluster on the M-sigma relation, color-coded by spin.  I have implemented new spin evolution formulae that I derived from GRMHD simulations, accounting for angular momentum loss from a magnetized jet. You can learn more about this model here. 

 

You can download luminosity functions and gravitational wave distributions from this model here and here.
