The LIGO Scientific Collaboration and the Virgo Collaborations recently announced the first observation of gravitational waves from merging neutron stars. The first gravitational-wave constraints on neutron-star matter have begun to shine new light on the properties of matter above nuclear density, cross-checking neutron-star measurements in electromagnetic astronomy and informing calculations in nuclear physics. Upgrades to the detectors are in progress, and we are soon to enter an era in which regular observations can used to learn about astrophysical sources. These first constraints will be supplanted by precision measurements that rely on an accurate understanding of how neutron star matter affects gravitational waves. In the proposed work, the CSUF students will explore the impact of dense matter on gravitational waves. This research introduces them to the science community, sparking future participation in gravitational astrophysics, data science, and engineering.The CSUF group will develop on-the-fly hybrid waveform infrastructure within LIGO software, connecting expensive numerical mergers to long analytic inspirals with desired parameters, yielding waveforms spanning LIGO's entire frequency band and quantifying accuracy requirements. They will determine and work to reduce the systematic errors in gravitational-wave parameter estimation techniques using multiple neutron-star waveform models and simulations. These efforts will connect the information coming from gravitational-wave observations with the broader astrophysical context of dense neutron-star matter and microphysics.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

Ligo科学合作和处女座合作最近宣布了合并中子星的重力波的首次观察。对中子明星物质的第一个重力波限制已经开始为核密度高于核密度的物质的特性提供新的启示，并在电磁天文学中进行了交叉检查中子星测量，并告知核物理学中的计算。对探测器的升级正在进行中，我们很快就会进入一个可以使用常规观察来学习天体物理来源的时代。这些第一个约束将被精确测量所取代，这些测量依赖于对中子恒星物质的准确理解会影响重力波。在拟议的工作中，CSUF学生将探索密集物质对引力波的影响。这项研究向他们介绍了科学界，引发了未来参与引力天体物理学，数据科学和工程。CSUFGroup将在LIGO软件中开发在Fly Hybrid Wove基础架构中，将昂贵的数值合并与长期分析的启发器连接到所需的启发器中，从而使波浪跨度跨度的spanning Ligo的整个频率频段要求和量化频率率需求。他们将确定并努力使用多个中子星波形模型和仿真来减少重力波参数估计技术中的系统误差。这些努力将将来自重力波观测的信息与密集的中子星和微物理学的更广泛的天体物理背景联系起来。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来进行评估的。
