Thermal Spectra of Warped and Broken Accretion Disks
Published 2025-01-01“…The resulting accretion disks are subject to Lense–Thirring precession, and hence torque. Analytical calculations and simulations show that Lense–Thirring precession will warp, and, for large misalignments, fracture the disk. …”

Radiative properties and QPOs around charged black hole in Kalb–Ramond gravity
Published 2025-02-01“…The frequency of Keplerian orbits and the radial and vertical oscillations of the particles along stable orbits are calculated and applied to analyze the existence of QPO in relativistic precession, warped disc, and epicyclic resonance models. …”

Flexible and cost-effective deep learning for accelerated multi-parametric relaxometry using phase-cycled bSSFP
Published 2025-02-01“…In this study, feed-forward deep neural network (DNN)- and iterative fitting-based frameworks are compared for multi-parametric (MP) relaxometry based on phase-cycled balanced steady-state free precession (pc-bSSFP) imaging. The performance of supervised DNNs (SVNN), self-supervised physics-informed DNNs (PINN), and an iterative fitting framework termed motion-insensitive rapid configuration relaxometry (MIRACLE) was evaluated in silico and in vivo in brain tissue of healthy subjects, including Monte Carlo sampling to simulate noise. …”

Particle motion and QPOs around Euler-Heisenberg black hole immersed in cold dark matter halo
Published 2025-03-01“…The epicyclic oscillations of particles in proximity to stable circular orbits have been examined, and the phenomenon of periastron precession has been addressed. Additionally, we examine the collision of particles and the center of mass energy in proximity to the black hole's horizon. …”
