The orientation of jet axis with respect to our line of sight not only govern the AGN unification theory but also significantly affects estimates of black hole mass, accretion rates, and luminosities. Current orientation predictors, such as radio core dominance—which measures the amplified emission from the jet base (‘core’) due to Doppler boosting relative to the AGN’s total power—are often biased because survey data frequently lacks the resolution to distinguish between the core and extended jet regions.

I led the observations and analysis of high-resolution Very Large Array (VLA) radio data (0.2′′ at 10 GHz) of 147 radio-loud quasars as part of my PhD dissertation. In Maithil et al. (2020), I demonstrated that about 40% of the sample had systematically higher core brightness in radio survey measurements compared to high-resolution data, even after accounting for variability. This work established an accurate approach for measuring AGN orientation, which is crucial for correctly interpreting their physical properties and jet dynamics.
