As a Harvard-Smithsonian Center for Astrophysics Postdoctoral Fellow, I lead research on X-ray jet emission mechanisms in quasars across cosmic time. By integrating cutting-edge observational techniques with sophisticated analytical modeling, I developed novel method to characterize these enigmatic phenomena.

High-redshift radio-loud quasars are essential to understanding early SMBH growth, yet their X-ray emissions are not well understood. While inverse Compton (IC) scattering of cosmic microwave background (CMB) photons by relativistic jet electrons is thought to be a dominant mechanism, its role remains uncertain. To resolve this, I combine deep X-ray observations with high-resolution radio data and developed semi-analytical models, demonstrating that IC/CMB significantly contributes to X-ray emissions, especially at high redshifts (e.g., Fig 1). My findings provide a consistent explanation for the origin of X-ray emission, helping to fill a critical gap in understanding how jets evolve and interact with their environments over cosmic time.
