Black Hole

Lensing of space time around a black hole. At Oxford we study black holes observationally and theoretically on all size and time scales - it is some of our core work.

My current research covers a range of topics with a focus on understanding the connection between galaxies and their dark matter halos using large galaxy surveys. I am currently in my third DPhil year under the supervision of Prof Matt Jarvis.

I specifically utilise optical data from HSC, VOICE and near-IR data from VIDEO and UltraVISTA in three independent fields to overcome cosmic variance; COSMOS, XMM-LSS and ECDF-S, with total area of 9.3 deg2. I measure galaxy clustering using the angular two-point correlation function and compute halo properties using halo occupation distribution (HOD) modelling. This allows me to look into the evolution of halo masses, satellite fractions, galaxy bias and stellar-to-halo-mass-ratio (SHMR) for different stellar mass galaxies. 

My main research objective is to better understand how different galaxies occupy dark matter halos and how this evolves with cosmic time.
