Radio Modeling of Dual Active Galactic Nuclei
Summer 2026–Present
Graduate Researcher, Center for Relativistic Astrophysics, Georgia Institute of Technology
Co-advisors: David R. Ballantyne (PI) and Tamara Bogdanović (Co-PI) · Funding: NSF AST-2407658, “The Population and Evolution of Dual AGNs at Radio Wavelengths: Predictions for the ngVLA”
- Develop a theoretical and computational framework for predicting radio emission from dual AGNs in post-merger galaxies, with applications to searches for SMBH pairs.
- Connect host-galaxy and SMBH properties from IllustrisTNG with pre-existing orbital-evolution calculations to model the evolving accretion and radio-emission properties of the pair.
- Model accretion from magnetized gas and relativistic jet power, considering the dependence on the black holes’ motion and the surrounding galactic environment.
- Calculate radio synchrotron spectra, including synchrotron self-absorption, to predict the fluxes and spectral properties of the two AGN cores.
- Investigate how radio detectability depends on projected separation, redshift, host-galaxy properties, and observing frequency, toward predictions for next-generation Very Large Array (ngVLA) surveys.
