Cosmological Evolution of the Randall-Sundrum II Model with Running Vacuum: A Special Class of Solutions

Hao Yu, Jin Li, Zi-Chao Lin

In this work, we construct a novel cosmological framework by integrating the running vacuum model into the Randall-Sundrum II braneworld scenario. We derive a special class of anal…

Qualitative Shadow Anomaly as a Smoking-gun Signature of Nonmetricity

Zi-Chao Lin, Hao Yu, Yu-Xiao Liu +1

In general relativity and its metric-formalism extensions, the innermost stable circular orbit and the photon ring of a charged black hole contract as the charge increases. In this…

The constraints on the stochastic gravitational wave background from cosmic strings by an electromagnetic resonance system

Jin Li, Meijin Li, Nan Yang +6

As one of the primary detection targets for contemporary gravitational wave (GW) observatories, the stochastic gravitational wave background (SGWB) holds significant potential for…

Shadows, Quasinormal Modes, and Optical Appearances of Black Holes in Horndeski Theory

Zhi Luo, Jin Li, Ke-Jian He +1

This work describes the motion of photons in black hole (BH) spacetimes within the framework of Horndeski theory. We focus on the shadows, quasinormal modes (QNMs) and optical appe…

Holographic entropy bound and a special class of spherical systems in cosmology

Hao Yu, Zi-Chao Lin, Jin Li

The holographic entropy bound is discussed in cosmology. Inspired by the work of Fischler and Susskind [hep-th/9806039], we aim to define a special class of spherical systems in co…

Observational appearance and additional photon rings of the asymmetric thin-shell wormhole in Horndeski theory

Zhi Luo, Hao Yu, Jin Li

In this paper, we study the observational appearance of the asymmetric thin-shell wormhole (ATW) in Horndeski theory by employing the ray-tracing method. We first calculate the eff…
