Extremal Scalarization of Charged Black Holes: Miransky Scaling across Reissner-Nordström Extremality
Hong Guo, Yun Soo Myung, Lijing Shao
We study spontaneous scalarization near and at extremality in Einstein-Maxwell-scalar theory. As Reissner-Nordström (RN) extremality is approached from below, the nonextremal scala…
Asymptotically-flat Black holes in Bumblebee gravity: Exact solutions and Thermodynamics
Jinbo Yang, Zhan-Feng Mai, Dicong Liang +1
We construct analytic solutions to the bumblebee gravity theory in static and spherically symmetric spacetimes, where the bumblebee vector field admits only a non-vanishing tempora…
Constraining Ultralight Scalar Dark Matter in the Galactic Center with the S2 Orbit
Jiang-Chuan Yu, Yan Cao, Lijing Shao
The dense environment of our Galactic Center (GC) offers a unique laboratory for probing ultralight dark matter (ULDM). We explore the prospect of detecting a scalar ULDM field thr…
A Realistic Pulsar -- Supermassive Black Hole Timing Model
Zexin Hu, Ziming Wang, Lijing Shao
Timing observation of pulsars orbiting around a supermassive black hole (SMBH) can measure the spacetime around the SMBH to a high precision and thus be a novel probe of the gravit…
Scalarized neutron stars with a highly relativistic core in scalar-tensor gravity
Peixiang Ji, Lijing Shao
Compact stars in scalar-tensor (ST) gravity have been extensively investigated, but relatively few studies have focused on highly relativistic neutron stars (NSs) with an extremely…
Bumblebee cosmology: The FLRW solution and the CMB temperature anisotropy
Rui Xu, Dandan Xu, Lars Andersson +2
We put into test the idea of replacing dark energy by a vector field against the cosmic microwave background (CMB) observation using the simplest vector-tensor theory, where a mass…
Neutron stars in the bumblebee theory of gravity
Peixiang Ji, Zhuhai Li, Lirui Yang +3
Recently, theoretical studies on the bumblebee gravity model, a nonminimally-coupled vector-tensor theory that violates the Lorentz symmetry, have flourished, with a simultaneous i…
Scalar Dark Energy Models and Scalar-Tensor Gravity: Theoretical Explanations for the Accelerated Expansion of Present Universe
Peixiang Ji, Lijing Shao
The reason for the present accelerated expansion of the Universe stands as one of the most profound questions in the realm of science, with deep connections to both cosmology and f…
