Description
Narrow Line Seyfert 1{NLS1} galaxies, defined by narrow emission lines and small black hole masses, reveal intriguing commonalities with blazars, renowned for their intense and beamed relativistic jet emissions. This paper reviews the evolving unification scheme of NLS1s and blazars. Unification models for AGNs have long been proposed in which orientation f AGN emitting axis to the line of sight causes the apparent differences between various subclasses of the AGN. Recent multi-wavelength observations have surprisingly indicated the presence of relativistic jets in NLS1 galaxies, and this has been a prompt to the proposed extended unification model. Nevertheess, questions persist about transitional objects and potential orientation-independent differences. Understanding the unity between NLS1 galaxies and blazars not only reshapes our perception of these cosmic entities but also deepens our understanding of the fundamental mechanisms underlying the cosmos.
