Computational modeling of astrophysical phenomena has grown in sophistication and realism, leading to a diversity of complex simulation platforms, each utilizing its own mechanism and format for representing particles and fluids. Similarly, most of the data analysis is conducted with tools developed in isolation and targeted to a specific simulation platform or research domain; very little systematic and direct technology transfer between astrophysical researchers exists. The yt project is a parallel analysis and visualization toolkit designed to support a collaborative community of researchers as they focus on answering physical questions, rather than the technical mechanics of reading, processing and visualizing data formats. This project will enable the development of advanced, physics-based modules that apply universally across simulation codes, advancing scientific inquiry and enabling more efficient utilization of computational and human resources. In doing so, it will help advance a myriad of research goals from the study of black hole binaries to the growth of cosmic structure. In addition, the project will serve as a touchstone for collaboration and cross-code utilization between many groups studying diverse phenomena. Moreover, the project will be developed through a community-oriented process, engaging a wide range of participants.The infrastructure development in this research will enable these capabilities by broadening the applicable simulation platforms within yt, enabling cross-code utilization of microphysical solvers and physics modules and in situ analysis, and developing collaborative platforms for the exploration of astrophysical datasets. In particular, it will develop the capabilities of yt in three primary mechanisms. The first is to enable support for additional, fundamentally different simulation platforms such as smoothed particle hydrodynamics, unstructured mesh, and non-Cartesian coordinate systems. The second is to provide simulation instrumentation components to ease the process of developing simulation codes, interfacing and exchanging technology between those simulation codes, and to enable deeper, on-the-fly integration of astrophysical simulation codes with yt and other analysis toolkits. The final focus is on developing interface components to enable collaborative and interactive exploration of data utilizing web-based platforms. An explicit goal of this SI2-SSE project is the development of collaborative relationships between scientists, furthering the development of the field as a whole. By conducting all business in the open with a focus on developing and encouraging collaborative, welcoming environments for contributors and researchers, this SSE will help to foster a level playing field that is more accessible to all parties, particularly women and underrepresented minorities. An explicit milestone of this project is to streamline the process of conducting direct outreach through scientific visualization, greatly expanding the domains and individuals engaged in STEM-based public outreach.

天体物理现象的计算建模变得越来越复杂和真实，导致了复杂的模拟平台的多样性，每个平台都利用自己的机制和格式来表示粒子和流体。 同样，大多数数据分析都是使用单独开发的工具进行的，并且针对特定的模拟平台或研究领域；天体物理学研究人员之间几乎没有系统和直接的技术转让。 yt 项目是一个并行分析和可视化工具包，旨在支持研究人员的协作社区，因为他们专注于回答物理问题，而不是读取、处理和可视化数据格式的技术机制。 该项目将实现先进的、基于物理的模块的开发，这些模块普遍适用于模拟代码，推进科学探究并实现计算和人力资源的更有效利用。 这样做，它将有助于推进从黑洞双星研究到宇宙结构增长的无数研究目标。 此外，该项目将成为研究不同现象的许多小组之间协作和跨代码利用的试金石。此外，该项目将通过面向社区的流程进行开发，吸引广泛的参与者。本研究中的基础设施开发将通过扩大 yt 内适用的模拟平台来实现这些功能，从而实现微物理求解器和物理的跨代码利用模块和原位分析，并开发用于探索天体物理数据集的协作平台。 特别是，它将在三个主要机制中发展 yt 的能力。 第一个是支持其他根本不同的模拟平台，例如平滑粒子流体动力学、非结构化网格和非笛卡尔坐标系。 第二个是提供模拟仪器组件，以简化模拟代码的开发过程、这些模拟代码之间的接口和技术交换，并实现天体物理模拟代码与 yt 和其他分析工具包的更深入、动态集成。 最后的重点是开发界面组件，以利用基于网络的平台实现数据的协作和交互式探索。 SI2-SSE 项目的一个明确目标是发展科学家之间的合作关系，促进整个领域的发展。 通过公开开展所有业务，重点是为贡献者和研究人员发展和鼓励协作、热情的环境，该 SSE 将有助于营造一个对各方，特别是女性和代表性不足的少数族裔更容易参与的公平竞争环境。 该项目的一个明确里程碑是通过科学可视化简化直接推广的流程，极大地扩展了参与基于 STEM 的公共推广的领域和个人。
