黑洞并合的电磁对应物

Electromagnetic Counterparts to Black Hole Mergers

Jeremy D. Schnittman

摘要:

在双黑洞(BH)合并的最后时刻,系统的引力波(GW)亮度大于整个可观测宇宙的电磁输出之和。然而,GW与普通物质之间极弱的耦合使得这些波很难直接检测到。幸运的是,螺旋BH系统将与宿主星系中的任何周围物质发生强烈的相互作用-在纯粹的牛顿水平上,这种物质反过来可以产生在地球上可检测到的独特电磁(EM)信号。通过确定GW源的EM对应物,我们将能够研究合并BH的宿主环境,从而大大扩展像LISA这样的任务的科学产量。

英文摘要:

During the final moments of a binary black hole (BH) merger, the gravitational wave (GW) luminosity of the system is greater than the combined electromagnetic output of the entire observable universe. However, the extremely weak coupling between GWs and ordinary matter makes these waves very difficult to detect directly. Fortunately, the inspiraling BH system will interact strongly--on a purely Newtonian level--with any surrounding material in the host galaxy, and this matter can in turn produce unique electromagnetic (EM) signals detectable at Earth. By identifying EM counterparts to GW sources, we will be able to study the host environments of the merging BHs, in turn greatly expanding the scientific yield of a mission like LISA.
