Highly Ionized X-Ray-Emitting Gas in Active Galaxies

I use Chandra imaging spectroscopy and physical modeling to distinguish contributions from photoionized gas, shocks, and spatially extended nuclear outflows.

Scientific questions

Questions guiding this work

  1. 01

    What powers spatially extended soft X-ray emission around an active nucleus?

  2. 02

    How can photoionized plasma be distinguished from collisionally ionized gas and unresolved nuclear emission?

  3. 03

    What do the morphology, spectrum, and spatial scale of the X-ray-emitting phase reveal about possible feedback?

AGN 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.

Multiphase Outflows

I compare X-ray, molecular, and warm ionized gas observations to test whether spatially associated phases trace related outflow structures and how model-dependent energetics constrain possible feedback.

NewAthena

I develop science cases, spectral simulations, and prospective observing strategies for NewAthena, an ESA mission currently in study, using observations from Chandra, XMM-Newton, NuSTAR, and XRISM as preparation and exploring future coordination with LISA.
