Research area
Using spatially resolved multiwavelength observations to distinguish candidate dual active nuclei from complex structure around a single accreting supermassive black hole.
Observational approach
I compare compact Chandra, Hubble, and VLA centroids, separations, morphologies, and spectral evidence after registering each observation to a physically appropriate nuclear reference.
Observatories
Physical interpretation
Multiple compact peaks are treated as candidate active nuclei until their astrometry and multiwavelength properties disfavor a single AGN with shocked, photoionized, or jet-related structure.
Scientific questions
Do independent X-ray, optical, and radio peaks trace two accreting supermassive black holes or structure around one nucleus?
How precisely do the compact centroids and separations agree across wavebands?
What can close nuclear pairs reveal about the growth of supermassive black holes during galaxy interactions?
