Relativistic Thermal Emission from Accretion Disks in Kerr-MOG Spacetimes
Cheng Liu, Xu-fan Hu, Yosuke Mizuno +1
In Scalar-Tensor-Vector Gravity (STVG, also known as MOG), a massive vector field generates a repulsive fifth force that endows rotating black holes with a gravitational char…
Signature of iron line profile from a Kerr-like wormhole
Cheng Liu, Hoongwah Siew, Hong-Xuan Jiang +2
Broad, skewed iron K emission lines in the X-ray spectra of accreting black holes encode key information about the spacetime geometry of the innermost disk. While the Kerr metri…
Two distinct types of echoes in compact objects
Shui-Fa Shen, Kai Lin, Tao Zhu +3
In the black hole perturbation theory framework, two different physical pictures for echoes in compact objects have been proposed. The first mechanism interprets echoes as repeated…
The Heavier the Faster: A Sub-population of Heavy, Rapidly Spinning and Quickly Evolving Binary Black Holes
Wei-Hua Guo, Yin-Jie Li, Yuan-Zhu Wang +4
The spins of binary black holes (BBHs) measured from gravitational waves carry notable information of the formation pathways. Here we propose a quantity "dimensionless net spin" ($…
Observational test of spacetimes with the S2 star in the Milky Way galactic center
Jian-Ming Yan, Tao Zhu, Mustapha Azreg-Aïnou +2
A novel class of vacuum metrics expressible in analytical form was recently found for pure gravity, based on a groundwork put forth by Buchdahl in 1962. These Buchda…
Observational tests of asymptotically flat spacetimes
Tao Zhu, Hoang Ky Nguyen, Mustapha Azreg-Aïnou +1
A novel class of Buchdahl-inspired metrics with closed-form expressions was recently obtained based on Buchdahl's seminal work on searching for static, spherically symmetric metric…
