Insights in cosmology: the relevance of the connection
Ismael Ayuso, Mariam Bouhmadi-López, Che-Yu Chen +3
We explore the role of the affine connection in gravity, a modified theory where gravity is governed by non-metricity within the symmetric teleparallel framework. Although t…
Imaging a semi-classical horizonless compact object with strong redshift
Che-Yu Chen, Yuki Yokokura
The recent advancements in black hole imaging have opened a new era of probing horizon-scale physics with electromagnetic radiation. However, a feature of the observed images, a br…
Quasinormal modes of black holes encircled by a gravitating thin disk
Che-Yu Chen, Petr Kotlařík
The ringdown phase of gravitational waves emitted by a perturbed black hole is described by a superposition of exponentially decaying sinusoidal modes, called quasinormal modes (QN…
On the Possible Spacetime Structures of Rotating Loop Quantum Black Holes
Che-Yu Chen
To date, a mathematically consistent construction of effective rotating black hole models in the context of Loop Quantum Gravity (LQG) is still lacking. In this work, we start with…
Curved accretion disks around rotating black holes without reflection symmetry
Che-Yu Chen, Hsiang-Yi Karen Yang
Rotating black holes without equatorial reflection symmetry can naturally arise in effective low-energy theories of fundamental quantum gravity, in particular, when parity-violatin…
Traversable Wormhole in Einstein 3-Form Theory With Self-Interacting Potential
Mariam Bouhmadi-López, Che-Yu Chen, Xiao Yan Chew +2
We numerically construct a symmetric wormhole solution in pure Einstein gravity supported by a massive -form field with a potential that contains a quartic self-interaction term…
