Clumpy Outflows from Super-Eddington Accreting Black Holes I: Radiation Hydrodynamics Simulations and Observational Implications
Haojie Hu, Yuta Asahina, Shogo Yoshioka +2
Recent advances in X-ray spectroscopic observation have enabled researchers to reveal distinct clumpy structures in the super-Eddington outflows from the supermassive black hole in…
Back to Normal Again: Possible Destinies of JWST overmassive SMBHs and "Little Red Dots" in the View of Shin-Uchuu Simulation
Haojie Hu, Hiroto Yanagisawa, Moka Nishigaki +3
The James Webb Space Telescope (JWST) has enabled the discovery of hundreds of supermassive black holes (SMBHs) at redshifts . A non-negligible fraction of these SMBH…
Microlensing of non-singular black holes at finite size: a ray tracing approach
Jens Boos, Hao Hu
We study the gravitational microlensing of various static and spherically symmetric non-singular black holes (and horizonless, non-singular compact objects of similar size). For po…
Quasinormal Modes and Dynamical Evolution of Scalar Fields in the Einstein-Bumblebee Theory with a Cosmological Constant
Hao Hu, Guoxiong Zhu
This paper investigates the dynamic behavior of static, spherically symmetric black holes within the Einstein-Bumblebee gravity model with a cosmological constant, focusing on scal…
Forced non-conformal relativistic fluid from the Chamblin-Reall gravity
Chao Wu, Hao Hu, Ruohan Wang +1
The Chamblin-Reall gravity is a remarkable non-conformal platform for the fluid/gravity correspondence to achieve its maximum efficiency. When a probe scalar field that does not ch…
