Global existence of Euler-Korteweg equations with the non-monotone pressure
Zihao Song
We are concerned with the global solution of the compressible Euler-Korteweg equations in . In the case of zero sound speed , it is found that the p…
Decay of higher order derivatives for solutions to the compressible fluid model of Korteweg type
Zihao Song, Jiang Xu
We present a new derivation for the optimal decay of \textit{arbitrary} higher order derivatives for solutions to the compressible fluid model of Korteweg type. This approach…
Global existence and analyticity of solutions to the compressible fluid model of Korteweg type
Zihao Song, Jiang Xu
We are concerned with a system of equations in governing the evolution of isothermal, viscous and compressible fluids of Korteweg type, that can be used as…
Variation of Broad Emission Lines from QSOs with Optical/UV Periodicity to Test the Interpretation of Supermassive Binary Black Holes
Xiang Ji, Youjun Lu, Junqiang Ge +2
Periodic quasars have been suggested to host supermassive binary black holes (BBHs) in their centers, and their optical/UV periodicities are interpreted as caused by either the Dop…
Broad-line region configuration of the supermassive binary black hole candidate PG1302-102 in the relativistic Doppler boosting scenario
Zihao Song, Junqiang Ge, Youjun Lu +2
PG1302-102 is thought to be a supermassive binary black hole (BBH) system according to the periodical variations of its optical and UV photometry, which may be interpreted as being…
Testing the relativistic Doppler boost hypothesis for supermassive binary black holes candidates via broad emission line profiles
Zihao Song, Junqiang Ge, Youjun Lu +1
Optical periodicity QSOs found by transient surveys are suggested to be sub-parsec supermassive binary black holes (BBHs). An intriguing interpretation for the periodicity of some…
