The scarcity of quantum gravity (QG) inspired rotating black holes limits the progress of testing QG through observational data, such as that from the Event Horizon Telescope (EHT). Recently, the EHT imaged the supermassive black holes, Sgr A* reveal

The EHT observation revealed event horizon-scale images of the supermassive black holes Sgr A* and M87* and these results are consistent with the shadow of a Kerr black hole as predicted by general relativity. However, Kerr-like rotating black holes

In the disk-corona model, the X-ray spectrum of a stellar-mass black hole in an X-ray binary is characterized by three components: a thermal component from a thin and cold accretion disk, a Comptonized component from a hot corona, and a reflection co

We examine and compare the gravitational lensing, in the strong field limit, for the spherically symmetric string-inspired Euler-Heisenberg black holes, characterized by additional parameters $Q^2$ and $\alpha-\beta$, representing magnetic charge and

Lexical Semantic Change Detection (LSCD) is a complex, lemma-level task, which is usually operationalized based on two subsequently applied usage-level tasks: First, Word-in-Context (WiC) labels are derived for pairs of usages. Then, these labels are

We present a new model to calculate reflection spectra of thin accretion disks in Kerr spacetimes. Our model includes the effect of returning radiation, which is the radiation that is emitted by the disk and returns to the disk because of the strong

In this work, an efficient and robust isogeometric three-dimensional solid-beam finite element is developed for large deformations and finite rotations with merely displacements as degrees of freedom. The finite strain theory and hyperelastic constit
