具有ngVLA的科学：由引力波追踪的致密双星合并
Science with an ngVLA: Compact binary mergers as traced by gravitational waves
摘要：
鉴于最近令人眼花缭乱的发现GW 170817，我们讨论了几个新的科学机会，将出现在多信使时域天体物理学，如果像下一代甚大阵（ngVLA）的设施与地面引力波（GW）探测器协同工作。这些机会包括探测中子星（NS）-NS合并的广角喷出物和离轴余辉;能够直接测量NS-NS合并的无线电喷出物的大小;以及通过在无线电波长的宿主星系研究揭示紧凑双星合并的前身背后的物理学。我们的研究结果表明，由于其前所未有的灵敏度和分辨率，ngVLA将在瞬态无线电天空的多信使探索中实现变革性的结果。
英文摘要：
In light of the recent dazzling discovery of GW170817, we discuss several new scientific opportunities that would emerge in multi-messenger time-domain astrophysics if a facility like the next generation Very Large Array (ngVLA) were to work in tandem with ground-based gravitational wave (GW) detectors. These opportunities include probing wide-angle ejecta and off-axis afterglows of neutron star (NS)-NS mergers; enabling direct size measurements of radio ejecta from NS-NS mergers; and unraveling the physics behind the progenitors of compact binary mergers via host galaxy studies at radio wavelengths. Our results show that, thanks to its unprecedented sensitivity and resolution, the ngVLA will enable transformational results in the multi-messenger exploration of the transient radio sky.
