Description
The Narrow-Line Seyfert 1 Galaxy (NLS1) AGN, J1522+3934 was observed to study core-jet evolution, which is the observation of jets growing as frequency progresses. Core-jet evolution is important as it generates better understanding of the physics of jets that influence star formation through AGN feedback. Imaging and spectral analysis were performed in the X (8-12 GHz) and K (18-27 GHz) bands to study the morphology and mechanism of J1522+3934 with respect to frequency for three epochs, 28 April, 27 August and 29 September 2023. A compact and unresolved morphology was observed at the X, K and sub-bands for all epochs. The spectra were inverted, as result of absorption. Synchrotron-self and free-free absorption were plausible mechanisms at the stage of jet formation. Higher frequency and yearly-epoch observations are required to study significant effects in the formation and evolution of AGNs.
