Improved methods for the detection of gravitational waves associated with gamma-ray bursts

随着先进的ligo和先进的处女座引力波探测器的出现，人们期待已久的引力波天文学的诞生将在未来几年内发生。这些仪器将为研究自然界中最极端的现象和环境开辟一条新的通道，包括伽马射线暴、核心坍缩、超新星和黑洞合并。这些系统的内部引擎对电磁观测来说要么是模糊的，要么是固有的不可见的。此外，相关的引力波发射通常依赖于人们知之甚少的物理学，比如超核密度下物质的状态方程。因此，引力波将为这些天体物理系统提供令人兴奋的新探测，例如约束中子星状态方程，并为基础物理学和宇宙学的测试提供实验室。然而，实现引力波的潜力带来了一个重大挑战：探测和解释引力波的最先进技术需要精确的引力波发射理论模型，因此不适用于大多数引力波源。该项目旨在通过超越当前最先进的快速自动化分析、先进的信号/背景识别和波形重建技术，最大限度地科学利用引力波。该项目的目标是：(i)开发独立于模型的技术，以可靠地探测来自相对论瞬态事件的引力波，并确定信号结构；（ii）将这些应用于来自Advanced LIGO / Advanced Virgo网络的数据，以探测gw；和(

The long-anticipated birth of gravitational-wave astronomy willoccur in the next few years with the advent of the AdvancedLIGO and Advanced Virgo gravitational-wave detectors. Theseinstruments will open a new channel for studying the most extreme phenomena andenvironments found in nature, including gamma-ray bursts, core-collapsesupernovae, and black-hole mergers. The inner engines of these systems are eitherobscured or inherently invisible to electromagnetic observations. Furthermore, theassociated gravitational-wave emission typically depends on poorly understoodphysics, such as the equation-of-state of matter at supra-nuclear densities.Gravitational waves will therefore provide an exciting new probe of theseastrophysical systems, for example constraining the neutron star equation-of-state,and providing laboratories for tests of fundamental physics and cosmology. However,realising the potential of gravitational waves poses a significant challenge: state-of the-art techniques for detecting and interpreting gravitational waves require precisetheoretical models of the gravitational-wave emission, and hence are not applicableto most gravitational-wave sources. This project aims at maximising the scientificexploitation of gravitational waves through advancements beyond current state-of the-art in rapid automated analyses, advanced signal/background discrimination, andwaveform reconstruction. The goals of this project are: (i) to develop the model independenttechniques needed to robustly detect gravitational waves fromrelativistic transient events, and determine the signal structure; (ii) to apply these todata from the Advanced LIGO / Advanced Virgo network to detect GWs; and (
