BL Lac对象

BL Lac object

BL Lacertae物体或BL Lac物体是一种具有活跃星系核的活跃星系,并以其原型BL Lacertae命名。 与其他类型的活跃星系核相反,BL Lacs的特征在于快速且大幅度的通量变化和显着的光学偏振。 由于这些属性,类的原型最初被认为是一个变星。 当与具有强发射线的更多发光的活性核相比时,BL Lac物体具有由无特征非热连续体主导的光谱。 在无线电大声活跃星系核的统一方案中,观察到的BL Lacs的核现象学被解释为由于与观察者的视线紧密相关的相对论射流的影响。 BL Lacs被认为与低功率无线电星系本质上相同。 这些活跃的核主要在大量的球状星系。 从AGN分类来看,BL Lacs是一个blazar亚型。 所有已知的BL Lac与核心主导的无线电源相关联,其中许多显示出超光速运动。 A BL Lacertae object or BL Lac object is a type of active galaxy with an active galactic nucleus and is named after its prototype, BL Lacertae. In contrast to other types of active galactic nuclei, BL Lacs are characterized by rapid and large-amplitude flux variability and significant optical polarization. Because of these properties, the prototype of the class was originally believed to be a variable star. When compared to the more luminous active nuclei with strong emission lines, BL Lac objects have spectra dominated by a featureless non-thermal continuum. In the unified scheme of radio-loud active galactic nuclei, the observed nuclear phenomenology of BL Lacs is interpreted as being due to the effects of the relativistic jet that is closely aligned to the line of sight of the observer. BL Lacs are believed to be intrinsically identical to low-power radio galaxies. These active nuclei are hosted in massive spheroidal galaxies. From the point of AGN classification, BL Lacs are a blazar subtype. All known BL Lacs are associated with core dominated radio sources, many of them exhibiting superluminal motion.
