Research theme

Active Galactic Nucleus Feedback

I investigate how observations of X-ray-emitting and warm ionized gas, together with model-dependent energetics, test where black-hole winds may interact with and transfer energy or momentum to their host galaxies.

Scientific questions

Questions guiding this work

  1. 01

    Where do observations indicate that nuclear winds may interact with the surrounding interstellar medium, and what evidence would establish physical coupling?

  2. 02

    How do observed multiphase structures and measured gas properties change from nuclear to kiloparsec scales?

  3. 03

    Which measurements and model-dependent energetics most strongly constrain possible energy and momentum transfer to the host?
