论文摘要
磁铁是具有异常强的偶极子磁场的中子星，观察到显示一系列X射线燃烧行为，但燃烧机制尚不清楚。第三次观测高级LIGO和处女座的运行延伸从2019年4月1日延伸至2020年3月27日，并包含来自已知Magnetar SGR 1935+2154的X射线耀斑，以及新发现的磁场Swift J1818-1607。我们搜索与这些磁铁耀斑一致的引力波，并具有最低建模的相干搜索，这些搜索专门针对磁铁核心激发F-Modes产生的短期短期引力波，以及由gasi-periodic振动型在Giant of Glarares tails of Geriant Flarares中的Quasi-Periodic振荡所激发的长期引力。在本文中，我们报告了这些搜索的方法和敏感性估计以及天体物理的含义。
Magnetars are neutron stars with exceptionally strong dipole magnetic fields which are observed to display a range of x-ray flaring behavior, but the flaring mechanism is not well understood. The third observing run of Advanced LIGO and Virgo extended from April 1, 2019 to March 27, 2020, and contained x-ray flares from known magnetar SGR 1935+2154, as well as the newly-discovered magnetar, Swift J1818-1607. We search for gravitational waves coincident with these magnetar flares with minimally modeled, coherent searches which specifically target both short-duration gravitational waves produced by excited f-modes in the magnetar's core, as well as long-duration gravitational waves motivated by the Quasi-Periodic Oscillations observed in the tails of giant flares. In this paper, we report on the methods and sensitivity estimates of these searches, and the astrophysical implications.
