I study physical processes for accretion & ejection of matter
(termed inflows & outflows) from compact objects (namely, from
such systems as XRBs,
CVs,
& AGN).
Inflows and outflows are ubiquitous in astrophysics.
Relevant areas, simply judging from the categories listed on Scholarpedia,
include
cosmology, extragalactic astronomy, stellar astrophysics,
and solar & planetary physics. An essential skill in this line of work is the ability to correctly solve equations numerically; this is its own field: computational astrophysics. The equations that I attempt to solve are the Euler equations of gas dynamics and the equations of magnetohydrodynamics (MHD, see also here), either set of which form a coupled system of non-linear, partial differential equations. For some specific applications showing the great diversity and complexity of the solutions of these equations, found via simulations, see here.
