The 2nd International Workshop on Gravitational Waves and the Early Universe
1号楼集贤厅
北京大学中关新园
With the detection of gravitational waves from the merger of binary black holes by LIGO, we officially entered the era of gravitational wave cosmology. During the early universe, many interesting physical processes could generate gravitational waves, which were usually associated with new physics beyond the standard model. This opens up a new observational window for humanity to further uncover the origins of the universe and its matter content. These gravitational waves are generated at different epochs and propagate through the cosmic history until the present, which are redshifted to different frequency bands. In the recent future, various gravitational wave detection projects are planned, including CMB-S4, LiteBIRD, BICEP3/Keck Array, AliCPT utilizing the B-mode polarization of the cosmic microwave background radiation; NANOGrav, EPTA, PPTA, CPTA using pulsar timing arrays; LISA, Taiji, TianQin utilizing space-based gravitational wave interferometers; and ET, BBO for ground-based gravitational wave interferometers.
Recently, the NANOGrav, EPTA, and CPTA jointly announced strong evidence for the existence of a nanohertz stochastic gravitational wave background. This has reignited our interest in gravitational waves produced in the early universe.
In order to further advance research in relevant fields, we held the first International Workshop on Gravitational Waves and the Early Universe, which attracted more than 100 scholars from over a dozen domestic and international research institutions and universities. During the three days of the conference, participants engaged in extensive discussions on recent developments in observations and theory.
We are glad to announce that the 2nd International Workshop on Gravitational Waves and the Early Universe will be held from April 8th to 11th, 2024. Invited speakers include：

随着LIGO观测到双黑洞合并的引力波，人类正式进入引力波宇宙学时代。在早期宇宙中，很多有趣的物理过程都能产生引力波。它们通常都和超出标准模型的新物理相联系，是人类进一步揭开宇宙起源和物质起源的一个新的观测窗口。这些引力波诞生于宇宙的不同时期，可能出现在许多可探测频段上。未来十几年内将有不同的引力波探测计划进行探测。其中包括间接利用微波背景辐射B模偏振的CMB-S4、LiteBIRD、BICEP3/Keck Array、AliCPT；利用脉冲星测时阵列的NANOGrav, EPTA, PPTA, CPTA；空间引力波干涉仪的LISA、太极、天琴；地面引力波探测器的ET、BBO等。最近，NANOGrav, EPTA, CPTA等脉冲星测试阵列观测组同时宣布观测到纳赫兹随机引力波背景存在的强烈证据。这重新燃起了我们对早期宇宙中产生的引力波的兴趣。
我们曾于2023年10月13日至16日举办了第一届《引力波与早期宇宙》国际研讨会，共吸引了来自国内外十几个科研院所与高校的100余名学者参与。在三天的会议期间，参会学者利用24场学术报告和自由讨论，充分研讨了早期宇宙和引力波的相关领域的理论和观测问题的近期进展。
为了进一步推进相关领域的研究并促进国内外学者之间的合作与交流，我们将于2024年4月8日至11日举办第二届《引力波与早期宇宙》国际研讨会。邀请报告人包括：
| 安海鹏(清华大学) | 陈弦(北京大学) |
| 范锡龙(武汉大学) | 孔镇郁(梨花女子大学) |
| 韩文标(上海天文台) | 胡彬(北京师范大学) |
| 黄志琦(中山大学) | 门田健司(国科大杭州高等研究院) |
| Alexey Koshelev(上海科技大学) | 向山信治(京都大学基础物理学研究所) |
| 成子笃(京都大学基础物理学研究所) | 佐佐木节(东京大学Kavli数物连携宇宙研究机构) |
| 须山辉明(东京工业大学) | 田中贵浩(京都大学) |
| 汤勇(中国科学院大学) | 王博(中国科学技术大学) |
| 武雷(南京师范大学) | 鲜于中之(清华大学) |
| 山口昌英(韩国基础科学研究院) | 章颖理(同济大学) |
本次会议不收注册费，食宿自理。2024年4月8日（周一）报到，4月9日（周二）及4月10日（周三）两天会议，4月11日（周四）自由讨论、离会。
会议地点：北京大学中关新园1号楼集贤厅。地址：北京市海淀区中关村北大街126号。
为了方便外地来的老师参会，我们在中关新园预订了一些房间。如果您愿意入住，请在注册时勾选。我们将按照注册的时间顺序安排住宿。因为数量有限，有可能无法安排，还请您谅解。
本次会议由中国科学院理论物理研究所及北京大学高能物理研究中心联合举办，并受到科技部国家重点研发计划“引力波探测”专项项目“宇宙弦等新颖引力波源与随机引力波背景的特征和信号识别研究”(项目号2021YFC2203004)的资助。
