LIGO/Virgo探测伽马射线暴相关引力波的机会估计

Chance Estimations for Detecting Gravitational Waves with LIGO/Virgo Associated with Gamma Ray Bursts

Alexander Dietz

摘要:

短伽马射线暴(SGRB)被认为起源于两个致密天体的合并。如果这种情况是正确的,SGRB将伴随着强引力波的发射,可以被目前或计划中的GW探测器(如LIGO和Virgo)探测到。到目前为止还没有发现引力波。在本文中,我将使用一组SGRB观测到的红移,以适应一个模型描述的SGRB的累积数量作为红移的函数,以确定在附近的宇宙中的合并事件的速度。这些估计将用于在LIGO/Virgo的最新科学运行期间检测与短伽马射线暴相关的引力波的概率声明。增强和先进的探测器的机会估计也将作出,并从这项工作推导出的速率之间的比较将与现有的文献。

英文摘要:

Short Gamma Ray Bursts (SGRB) are believed to originate from the merger of two compact objects. If this scenario is correct, SGRB will be accompanied by the emission of strong gravitational waves, detectable by current or planned GW detectors, such as LIGO and Virgo. No detection of a gravitational wave has been made up to date. In this paper I will use a set of SGRB with observed redshifts to fit a model describing the cumulative number of SGRB as a function of redshift, to determine the rate of such merger events in the nearby universe. These estimations will be used to make probability statements about detecting a gravitational wave associated with a short gamma ray burst during the latest science run of LIGO/Virgo. Chance estimations for the enhanced and advanced detectors will also be made, and a comparison between the rates deduced from this work will be compared to the existing literature.
