Oscillation Modes and Gravitational Waves from Strangeon Stars

Kavli Affiliate: Lijing Shao | First 5 Authors: Hong-Bo Li, Yong Gao, Lijing Shao, Ren-Xin Xu, Rui Xu | Summary: The strong interaction at low energy scales determines the equation of state (EOS) of supranuclear matters in neutron stars (NSs). It is conjectured that the bulk dense matter may be composed of strangeons, which are […]

Magnetically driven accretion disc winds: the role of gas thermodynamics and comparison to ultra-fast outflows

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 […]

ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions — XI. From inflow to infall in hub-filament systems

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 […]

Cold Gas Reservoirs of Low and High Mass Central Galaxies Differ in Response to AGN Feedback

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 […]

Binaries Wandering Around Supermassive Black Holes Due To Gravito-electromagnetism

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 […]

Direct ultrafast parametric amplification pumped by a picosecond thin-disk laser

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 […]

ET White Paper: To Find the First Earth 2.0

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 […]
