Inspiraling streams of enriched gas observed around a massive galaxy 11 billion years ago
Shiwu Zhang, Zheng Cai, Dandan Xu +19
Stars form in galaxies, from gas that has been accreted from the intergalactic medium. Simulations have shown that recycling of gas-the reaccretion of gas that was previously eject…
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…
Variations of Broad Emission Lines from periodicity QSOs under the interpretation of supermassive binary black holes with misaligned circumbinary broad line regions
Xiang Ji, Junqiang Ge, Youjun Lu +1
Quasars with periodic light curves are considered as candidates of supermassive binary black hole (BBH) systems. One way for further confirmations may be searching for other charac…
Formation and Evolution of Binary Neutron Stars: Mergers and Their Host Galaxies
Qingbo Chu, Shenghua Yu, Youjun Lu
In this paper, we investigate the properties of binary neutron stars (BNSs) and their mergers by combining population synthesis models for binary stellar evolution (BSE) with cosmo…
SDSS-IV MaNGA: Stellar M/L gradients and the M/L-colour relation in galaxies
Junqiang Ge, Shude Mao, Youjun Lu +3
The stellar mass-to-light ratio gradient in SDSS band of a galaxy depends on its mass assembly history, which is imprinted in its morphology and gradients of…
