- How black holes influence the microphysical, energetic, and dynamical properties of their surroundings, e.g., accretion discs and relativistic jets.
- Understanding how radiation is produced in the vicinity of the event horizon and subsequently attenuated by intervening media, thereby providing key information about the black hole, the state of the accreting material, and the underlying theory of gravity.
- Calculating physically-accurate models of this radiation using a combination of theory, computational astrophysics, and observational data to construct synthetic images, spectra, and light-curves.
What I do
- I authored and maintain the general-relativistic radiation transport (GRRT) code, “BHOSS”, which solves the equations of covariant polarised radiation transport and fully incorporates the effects of both special relativity and general relativity (or any metric theory of gravity).
- By interfacing BHOSS with general-relativistic magnetohydrodynamics (GRMHD) simulations, I calculate the multi-frequency polarised emissions from turbulent plasmas surrounding black holes.
- These calculations enable constraints on black-hole mass and spin, accretion physics, and facilitate strong-field tests of gravity.
