ABSTRACT
Abstract Blazars are radio-loud active galactic nuclei whose jets have a very small angle to our line of sight. Observationally, the radio emissions mostly compact or compact-core with one-sided jet. With 2.″5 resolution at 3 GHz, Very Large Array Sky Survey (VLASS) enables us resolve structure some blazar candidates in sky north decl. −40°. We introduce an algorithm classify sources as either blazar-like non-blazar-like based on their morphology VLASS images. apply three existing catalogs, including one known blazars (Roma-BzCAT) and two identified by Wide-field Infrared Explorer colors emission (WIBRaLS, KDEBLLACS). show that all there objects morphologies inconsistent being blazars. Considering more than 12% unlikely be blazars, this analysis. Notably, we 3% Roma-BzCAT confirmed could misclassification morphology. The resulting table morphological classification is available online.
