The research is directed at finding environmental factors that are related to the switch-on of the general relativistic engine responsible for the few percent of accreting black holes that drive powerful relativistic jets. This is important since this will relate directly to constraints on the initial state and boundary conditions on numerical models of black hole driven jets.
Topics of research:
• long term 3-D MHD numerical simulations of black hole magnetospheres
• in depth high resolution VLBA monitoring of the nearby quasar MRK 231
• X-ray observations of quasars with polar broad UV absorption line outflows
• propensity for red (redward of the QSO systemic velocity) broad line emission excess in radio loud quasars that is accentuated for polar lines of sight
• discovery of excess narrow line widths of broad emission lines in broad absorption line quasars
• finding environmental factors that are related to the switch-on of the general relativistic engine responsible for a few percent of quasars driving powerful relativistic jets
• the study of 3-D numerical simulations of black hole magnetospheres and how they relate to observations of astrophysical jets
• using the jet in the Galactic black hole, GRS 1915+105, as a test case for black hole driven jets
