Gone with the wind? Potential gas inflow in the broad-line region of a QSO at traced by time-varying Balmer absorption
Xihan Ji, Dominic J. Walton, Francesco D'Eugenio +6
We report spectroscopic observations of a remarkable QSO, J115724.80-000455.56 at from the Dark Energy Spectroscopic Instrument (DESI) survey. This QSO exhibits variabili…
Formation of black hole stars via star--black hole collisions
Yanlong Shi, Qingru Hu, Zhenghao Xu +2
In dense stellar environments such as globular clusters and active galactic nucleus (AGN) disks, stellar-mass black holes (sBHs) may frequently collide with massive stars. We inves…
Dynamical formation of high-eccentricity compact binaries through BH--BH*/TZO collisions
Qingru Hu, Yanlong Shi, Douglas N. C. Lin +1
The rapidly accumulating discoveries of binary stellar-mass black-hole (sBH) coalescences, detected by LIGO, have opened a new window into the formation and evolution of compact bi…
Stellar mergers and chemical element mixing: implications for the metamorphic stellar evolution in AGN disks
Yanlong Shi, Xiaoshan Huang, Douglas N. C. Lin +1
Chemical mixing during stellar mergers can significantly influence the subsequent evolution of the merger remnant. We perform a suite of three-dimensional hydrodynamical simulation…
