Moving Toward Gravitational Wave Detection in Advanced LIGO

索尔森在锡拉丘兹的研究小组已经工作了二十年，以帮助开发LIGO引力波探测器，并通过其所做的观测为引力波的搜索做出贡献。在未来三年内，该小组将开发一种新技术，以揭示LIGO数据中过量（非高斯）干扰或“故障”的原因。他们将开发一个数据挖掘系统，以寻找受干扰的时间与各种控制和监测信号值之间的联系。这将允许探索控制系统中误差信号饱和导致对环境干扰额外敏感的可能性，以及其他可能导致控制通道和引力波输出之间时变耦合的机制。该项目的成功将使引力波信号的探测更加可靠，并将为未来与公众共享LIGO数据铺平道路。锡拉丘兹小组还将致力于改进高级LIGO对中子星星双星合并产生的引力波的搜索。将开发一个特别关注的管道，以充分利用该信号的所有特殊功能。这将提高Advanced LIGO探测这一关键科学目标信号的能力。当我们成功探测到引力波时，我们将能够以全新的方式探索宇宙。它将使我们能够对黑洞进行前所未有的观察，特别是检查它们是否像爱因斯坦的广义相对论所预测的那样。引力波探测技术的发展导致了美国在激光、真空系统和精密机械等方面的技术能力的进步。索尔森在锡拉丘兹的小组从事多层次的正规和非正规教育，包括本科生和研究生培训以及向公众推广。该小组还与卡迪夫大学的哈里柯林斯教授一起参与科学社会学的研究。

Saulson's research group at Syracuse has been working for two decades to help develop the LIGO gravitational wave detector and to contribute to the search for gravitational waves with the observations that it has made. In the coming three years, the group will develop a new technique to uncover the causes of excess (non-Gaussian) disturbances, or 'glitches',in LIGO's data. They will develop a data-mining system to look for the connection between times subject to disturbances and the values of a wide array of control and monitoring signals. This will allow the exploration of the possibility that saturation of error signals in control systems causes extra sensitivity to environmental disturbances, as well as other mechanisms that can cause time-varying couplings between control channels and the gravitational wave output. Success in this project will allow more confident detections of gravitational wave signals, and will ease the path to future sharing of LIGO data with the public. The Syracuse group will also work to improve Advanced LIGO's search for gravitational waves from the coalescence of a neutron star binary. A specially-focused pipeline will be developed to take full advantage of all of the special features of this signal. This will improve Advanced LIGO's ability to detect signals from this key science target.When we have succeeded in detecting gravitational waves, we will be able to explore the universe in a completely new way. It will enable us to make unprecedented observations of black holes, and in particular to check whether they behave as predicted by Einstein's General Theory of Relativity. Development of gravitational wave detection techniques has led to advances in U.S. technological capability in lasers, vacuum systems, and precision mechanics, among others. Saulson's group at Syracuse is engaged in formal and informal education at many levels, including undergraduate and graduate training and outreach to the general public. The group also participates in research on the sociology of science, in conjunction with Prof. Harry Collins of Cardiff University.
