Families of regular spacetimes and energy conditions
Zi-Liang Wang, Emmanuele Battista
We present a systematic method for constructing static, spherically symmetric regular spacetimes of Kerr-Schild type in general relativity that satisfy the weak energy condition. O…

Shadows of quintessence black holes: spherical accretion, photon trajectories, and geodesic observers
Ji-Wen Li, Zi-Liang Wang, Tao-Tao Sui
The presence of a quintessence-like field can influence the black hole shadow through three primary mechanisms: the dynamics of accretion flows, the trajectories of photons, and th…

Energy conditions in static, spherically symmetric spacetimes and effective geometries
Zi-Liang Wang, Emmanuele Battista
Classical energy conditions are investigated in generic static and spherically symmetric spacetimes. In setups with nonconstant , the appearance of horizons can sign…
