Kavli Affiliate: Feng Yuan | First 5 Authors: Weixiao Wang, De-Fu Bu, Feng Yuan, , | Summary: Winds are commonly observed in luminous active galactic nuclei (AGNs). A plausible model of those winds is magnetohydrodynamic (MHD) disc winds. In the case of disc winds from a thin accretion disc, isothermal or adiabatic assumption is usually […]
Kavli Affiliate: Ke Wang | First 5 Authors: Jian-Wen Zhou, Tie Liu, Neal J. Evans II, Guido Garay, Paul F. Goldsmith | Summary: We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using H$^{13}$CO$^{+}$ J=1-0 molecular line data obtained from the ATOMS survey. We find that filaments are ubiquitous […]
Kavli Affiliate: Jing Wang | First 5 Authors: Hong Guo, Michael G. Jones, Jing Wang, , | Summary: The growth of supermassive black holes, especially the associated state of active galactic nuclei (AGNs), is generally believed to be the key step in regulating star formation in massive galaxies. As the fuel of star formation, the […]

Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Zhongfu Zhang, , , | Summary: Extreme-mass-ratio inspirals (EMRIs) are important sources for space-borne gravitational-wave (GW) detectors. Such a source normally consists of a stellar-mass black hole (BH) and a Kerr supermassive BH (SMBH), but recent astrophysical models predict that the small body could also […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Peng Yuan, Dongfang Zhang, Guoqiang Xie, Kainan Xiong | Summary: Optical quadratic nonlinearity is ultrafast in nature, while parametric interaction usually manifests only the broadband characteristic. Enormous progress has been made toward broadband phase-matching for parametric amplification and wide applications. In existing devices of broadband […]
Kavli Affiliate: Subo Dong | First 5 Authors: Jian Ge, Hui Zhang, Weicheng Zang, Hongping Deng, Shude Mao | Summary: We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time, the occurrence rate and the orbital distributions of Earth-sized […]
Kavli Affiliate: Jing Wang | First 5 Authors: Wenxuan Wang, Chen Chen, Jing Wang, Sen Zha, Yan Zhang | Summary: For 3D medical image (e.g. CT and MRI) segmentation, the difficulty of segmenting each slice in a clinical case varies greatly. Previous research on volumetric medical image segmentation in a slice-by-slice manner conventionally use the […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Yuming Fu, Xue-Bing Wu, Linhua Jiang, Yanxia Zhang, Zhi-Ying Huo | Summary: Quasars behind the Galactic plane (GPQs) are important astrometric references and valuable probes of the Galactic gas, yet the search of GPQs is difficult due to severe extinction and source crowding in the Galactic plane. […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, Hui Li, Yosuke Mizuno, Fan Guo | Summary: The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the […]
