摘要
我们对 Seyfert 1 星系 NGC 5548 进行了多波长连续谱变化研究，以调查其吸积盘的温度结构。19 条重叠的连续谱光变曲线（1158 至 9157 埃）结合了 2014 年 1 月至 7 月 180 天期间 HST、Swift 和地面观测的同步数据。光变曲线的变化被解释为吸积盘对中心时变点源照射的反响响应。我们的模型得出了盘倾角 i、距离黑洞 1 光日处的温度 T1 以及温度-半径斜率 alpha。我们还推断了驱动光变曲线，发现它与硬 X 射线和软 X 射线光变曲线的相关性都很差，这表明在观测期间仅 X 射线可能无法驱动紫外和光学变化。我们还将光变曲线分解为明亮、微弱和平均吸积盘光谱。这些光谱位于标准黑体吸积盘在 吸积下预期光谱的下方。
