来源：光明日报 陈一帆介绍，纳赫兹频段的引力波主要产生于超大质量黑洞双星在缓慢绕转并逐渐靠近的过程中，是研 究宇宙中最巨大黑洞系统的重要窗口。最新的脉冲星计时阵列能谱数据显示，引力波背景整体上与超大 质量黑洞双星的理论预期一致，但在最低频段呈现出轻微偏离传统模型的趋势。这一特征提示，黑洞双 星的轨道演化可能并非仅由引力波辐射主导，而是受到其周围环境的影响。 研究团队将这一环境效应与黑洞双星轨道偏心率的演化同时纳入统一模型，并将理论预测与北美纳赫兹 引力波天文台合作组15年的观测数据进行对比分析。结果表明，引力波数据已经能够对星系中心的物质 密度给出有意义的限制，其推断得到的密度范围，与银河系以及邻近星系M87星系中心区域已知的恒星 分布情况相符。研究还表明，星系中心环境对黑洞演化的影响，有时会与黑洞双星具有较大偏心率的椭 圆轨道产生相似的观测效果，从而使两种因素在引力波信号中不容易被直接区分。为此，研究团队系统 测试了多种模型假设，发现无论采用何种合理的参数化方式，推断得到的物质密度尺度都保持稳定，从 而增强了结论的可靠性。 本报北京2月8日电 记者张晓华 从上海交通大学李政道研究所获悉，该研究所青年学者陈一 ...
