Hydrodynamical Simulations of the Triggering of Nuclear Activities by Minor Mergers of Galaxies
Chao Yang, Junqiang Ge, Youjun Lu
Major mergers of galaxies are considered to be an efficient way to trigger Active Galactic Nuclei and are thought to be responsible for the phenomenon of quasars. This has however…
Investigating the co-evolution of massive black holes in dual active galactic nuclei and their host galaxies via galaxy merger simulations
Chao Yang, Junqiang Ge, Youjun Lu
Major galaxy mergers can trigger nuclear activities and are responsible for high-luminosity quasi-stellar objects /active galactic nuclei (QSOs/AGNs). In certain circumstances, suc…
Streaming Instability with Multiple Dust Species: II. Turbulence and Dust-Gas Dynamics at Nonlinear Saturation
Chao-Chin Yang, Zhaohuan Zhu
The streaming instability is a fundamental process that can drive dust-gas dynamics and ultimately planetesimal formation in protoplanetary discs. As a linear instability, it has b…
Kozai-Lidov oscillations triggered by a tilt instability of detached circumplanetary discs
Rebecca G. Martin, Zhaohuan Zhu, Philip J. Armitage +2
Circumplanetary discs can be linearly unstable to the growth of disc tilt in the tidal potential of the star-planet system. We use three-dimensional hydrodynamical simulations to c…
