Observational and Thermodynamic aspects of one-dimensional Dark Energy EoS parametrization models
Anirban Chatterjee, Yungui Gong
We investigate the observational and thermodynamic viability of Gong-Zhang (GZ) Type~I (GZ1) and Type~II (GZ2) dark-energy parametrizations using late-time cosmological probes incl…
Numerical simulations of primordial black hole formation via delayed first-order phase transitions
Zhuan Ning, Xiang-Xi Zeng, Rong-Gen Cai +1
We perform fully nonlinear, spherically symmetric numerical simulations of superhorizon false-vacuum-domain (FVD) collapse in a coupled gravity-scalar-fluid system to study primord…
Imaging Signatures of the Israel Junction: Photon Ring Evolution in Dynamical Thin Shell Schwarzschild Spacetimes
Li-Ming Cao, Long-Yue Li, Xia-Yuan Liu
We study the images of black holes by gluing two Schwarzschild spacetimes with a thin shell where the Israel junction conditions are satisfied. By studying the refraction law for n…
Differential topology and micro-structure of black hole in Einstein-Euler-Heisenberg spacetimes with exponential entropy
Muhammad Yasir, Tong Lining, Kazuharu Bamba
Exact black holes in the Einstein Euler-Heisenberg theory are explored with an exponential entropy framework by using the topological current -mapping theory. The topology class…
Images and photon regions of continuous photon sphere spacetime
Long-Yue Li, Xia-Yuan Liu, Rong-Gen Cai +2
We study images of spacetimes containing continuous photon spheres (CPS). For a self-gravitating, isotropic, spherically symmetric spacetime with CPS, we find that a thin accretion…
Observational constraints on inflationary models with non-minimally derivative coupling by ACT
Qing Gao, Yanjiang Qian, Yungui Gong +1
The most recent data release from the Atacama Cosmology Telescope (ACT) reveals a larger value of the scalar spectral tilt , ruling out a broad class of inflationary attractor…
Gravitational wave cosmology
Ligong Bian, Rong-Gen Cai, Yu-Qi Dong +18
Gravitational waves (GWs) originating from cosmological sources offer direct insights into the physics of the primordial Universe, the fundamental nature of gravity, and the cosmic…
Dynamical friction can flip the hierarchical three-body system
Li Hu, Rong-Gen Cai, Shao-Jiang Wang
In recent years, the long-term effects of non-linear perturbations were found to be important for the evolution of the hierarchical triple system, which, for the central third body…
Distinguishing dark matter halos with Extreme mass ratio inspirals
Yang Zhao, Ning Dai, Yungui Gong
Using the static, spherically symmetric metric for a black hole (BH) immersed in dark matter (DM) halo characterized by Hernquist, Burkert, and Navarro-Frenk-White (NFW) density di…
Observational constraints on generic models of non-minimal curvature-matter coupling
Anirban Chatterjee, Akshay Panda, Abhijit Bandyopadhyay
We investigate two classes of non-minimally coupled curvature-matter models in the FLRW universe with a perfect fluid and analyze their cosmological implications using Supernova Ia…
QED Effects on Kerr-Newman Black Hole Shadows
Shaobing Yuan, Changkai Luo, Zezhou Hu +2
Incorporating first-order QED effects, we explore the shadows of Kerr-Newman black holes with a magnetic charge through the numerical backward ray-tracing method. Our investigation…
Sky localization of space-based detectors with time-delay interferometry
Tong Jiang, Yungui Gong, Xuchen Lu
The accurate sky localization of gravitational wave (GW) sources is an important scientific goal for space-based GW detectors. The main differences between future space-based GW de…
