Investigating shadow images and rings of the charged Horndeski black hole illuminated by various thin accretions

Xiao-Jun Gao, Tao-Tao Sui, Xiao-Xiong Zeng +2

In this paper, we investigate the shadows and rings of the charged Horndeski black hole illuminated by accretion flow that is both geometrically and optically thin. We consider two…

On the gauge dependence of scalar induced secondary gravitational waves during radiation and matter domination eras

Arshad Ali, Ya-Peng Hu, Mudassar Sabir +1

We revisit the vital issue of gauge dependence in the scalar-induced secondary gravitational waves (SIGWs), focusing on the radiation domination (RD) and matter domination (MD) era…

Gravitational lensing by a charged spherically symmetric black hole immersed in thin dark matter

Xiao-Jun Gao, Xiao-kun Yan, Yihao Yin +1

We investigate the gravitational lensing effect around a spherically symmetric black hole, whose metric is obtained from the Einstein field equation with electric charge and perfec…

Phase Transitions and Critical Phenomena for the FRW Universe in an Effective Scalar-Tensor Theory

Haximjan Abdusattar, Shi-Bei Kong, Hongsheng Zhang +1

We find phase transitions and critical phenomena of the FRW (Friedmann-Robertson-Walker) universe in the framework of an effective scalar-tensor theory that belongs to the Horndesk…
