New results on the dynamics of critical collapse
Jun-Qi Guo, Yu Hu, Pan-Pan Wang +1
We study the dynamics of the critical collapse of a spherically symmetric scalar field. Approximate analytic expressions for the metric functions and matter field in the large-radi…
Massive Gauge Theory with Quasigluon for Hot : Phase Transition and Thermodynamics
Jiang Zhu, Jun Guo, Zhaofeng Kang
It is challenging to build a model that can correctly and unifiedly account for the deconfinement phase transition and thermodynamics of the hot pure Yang-Mills (PYM) syste…
Strength of the naked singularity in critical collapse
Jun-Qi Guo, Lin Zhang, Yuewen Chen +2
The critical collapse of a scalar field is a threshold solution of black hole formation, in which a naked singularity arises. We study here the curvature strength of this singulari…
Accretion disks around naked singularities
Jun-Qi Guo, Pankaj S. Joshi, Ramesh Narayan +1
We investigate here the thermal properties of accretion disks in a spacetime for some galactic density profiles in spherical symmetry. The matter distributions have a finite outer…
Dynamics near the central singularity in spherical collapse
Jun-Qi Guo
We study the dynamics near the central singularity in spherically symmetric collapse of a massless scalar field toward Schwarzschild black hole formation. The equations of motion t…
Dynamics of critical collapse
Jun-Qi Guo, Hongsheng Zhang
Critical collapse of a massless scalar field in spherical symmetry is systematically studied. We combine numerical simulations and asymptotic analysis, and synthesize critical coll…
