天文学家发现了迄今最遥远的蝎虎 BL型类星体(blazar),位于红移约 7.0 的宇宙时期,相当于宇宙年龄不到 8 亿年。蝎虎BL型类星体是一类活跃星系核,其特征是中心的超大质量黑洞驱动高速相对论性喷流,且喷流方向几乎直接对准地球。此次发现的天体 VLASS J041009.05−013919.88(J0410−0139)其核心包含一颗质量约为太阳 7 亿倍的超大质量黑洞。其电波辐射的变化、致密结构与 X 射线特征证实,它是一颗喷流几乎直接对准地球的蝎虎BL型类星体。J0410−0139 的发现暗示,在早期宇宙中可能存在更多类似的喷流源。这些喷流可能促进黑洞快速增长,并显著影响其宿主星系的演化。
