NewAthena X-Ray Astronomy

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.

Scientific questions

Questions guiding this work

  1. 01

    Which proposed feedback measurements could use NewAthena’s planned high-throughput imaging and high-resolution X-ray spectroscopy?

  2. 02

    How can XRISM spectroscopy and observations from Chandra, XMM-Newton, and NuSTAR provide the preparatory measurements needed for NewAthena?

  3. 03

    Which future joint NewAthena and LISA observations could connect electromagnetic and gravitational-wave views of black-hole accretion, winds, and mergers?

Highly Ionized X-Ray-Emitting Gas

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

Spectroscopy & Tools

I develop reproducible spatially resolved X-ray spectroscopy workflows for calibration, extraction, and spectral modeling that support, but do not by themselves validate, physical inferences about faint extended gas, ionization, and energetics.

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.
