This special volume includes contributions from some of the most relevant scientists who have participated in the IWARA 2020 Video Conference. The series of meetings known by the acronyms IWARA, STARS, and SMFNS,—more than a congregation of events, students and researchers which in itself would be extremely important for science—became in last years a kind of platform for scientific and academic projects, partnerships and presentation of high-quality research contributions describing original and unpublished results on several topics related as new phenomena and new states of matter in the Universe, general relativity, gravitation, cosmology, astrophysics, particle and nuclear physics, and topics related. And the scientists participating in this volume, perfectly integrated with this design, bring more than just a glimpse into the technical toolbox of their work, be it theoretical or experimental. In addition to international scientific recognition, these researchers are mentors of students and young researchers, and demonstrate, in these contributions, also glimpses of systematically complex decisions made about the interpretation of data, about which problems are relevant to pursue, thus contributing a lot to the craft of science and its development.

特别卷，序言——第九届天文学和相对论天体物理学国际研讨会：从夸克到宇宙

这本特刊包括一些参与 IWARA 2020 视频会议的最相关科学家的贡献。以首字母缩写词 IWARA、STARS 和 SMFNS 为人所知的一系列会议——不仅仅是事件、学生和研究人员的聚会，这些会议本身对科学非常重要——在去年成为了一种科学和学术项目的平台，合作伙伴关系和高质量研究贡献的介绍，描述与宇宙中的新现象和新物质状态、广义相对论、引力、宇宙学、天体物理学、粒子和核物理学以及相关主题相关的几个主题的原始和未发表的结果。而参与这本书的科学家们，与这个设计完美结合，不仅仅是一瞥他们工作的技术工具箱，无论是理论的还是实验的。除了国际科学界的认可，这些研究人员还是学生和年轻研究人员的导师，并在这些贡献中展示了对数据解释做出的系统性复杂决策的一瞥，以及与追求哪些问题相关的问题，从而为科学的工艺及其发展。
