Contribution

It introduces a comprehensive analysis of jet image modeling with multiple lens mass distribution models, highlighting the impact on Hubble constant estimation.

Findings

Jet image modeling depends significantly on lens mass distribution.

The Hubble constant estimate varies with model parameters.

Circular structures in lens models affect the results.

Abstract

The jets image modelling of gravitationally lensed sources have been performed. Several basic models of the lens mass distribution were considered, in particular, a singular isothermal ellipsoid, an isothermal ellipsoid with the core, different multi-components models with the galactic disk, halo and bulge. The obtained jet images were compared as with each other as with results of observations. A significant dependence of the Hubble constant on the model parameters was revealed for B0218+357, when the circular structure was took into account.
