Strong gravitational lensing effects around rotating regular black holes

Physics Letters B
In this letter, we investigate the strong gravitational lensing effects around two classes of rotating regular black holes, which behave as non-singular Minkowski core at the center.

Rotating Black Hole Thermodynamics with a Particle Probe

, 2011
The thermodynamics of Myers-Perry black holes in general dimensions are studied using a particle probe. When undergoing particle absorption, the changes of the entropy and irreducible mass are shown to be dependent on the particle radial momentum.

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Scalarization of Taub-NUT black holes in extended scalar-tensor-Gauss-Bonnet theory

Journal of High Energy Physics
Recently, the scalarization of the Schwarzschild black hole has been extensively studied. In this work, we explore the scalarization of the Taub-NUT black hole within the context of the extended scalar-tensor-Gauss-Bonnet theory, which admits a Ricci ...

Non-extensive entropic corrected thermal stability and geometries of well-known black holes

Nuclear Physics B
In this study, we investigate the thermodynamic stability and geometries of well-known black holes such as the spherical static black hole, charged Einstein-Gauss-Bonnet black hole and R-N black hole of the dyadosphere in the presence of Barrow and Gauss-

Gluing gravitational blocks for AdS black holes

Journal of High Energy Physics, 2019
We provide a unifying entropy functional and an extremization principle for black holes and black strings in AdS4 × S 7 and AdS5 × S 5 with arbitrary rotation and generic electric and magnetic charges.

The Dynamical Evolution of Stellar Black Holes in Globular Clusters

, 2014
Our current understanding of the stellar initial mass function and massive star evolution suggests that young globular clusters may have formed hundreds to thousands of stellar-mass black holes, the remnants of stars with initial masses from $\sim 20 ...

Circular‐Polarization‐Sensitive Organic Photodetectors with a Chiral Nanopatterned Electrode Inverse‐Designed by Genetic Algorithm

Advanced Functional Materials, EarlyView.
A chiral photodetector capable of selectively distinguishing left‐ and right‐handed circularly polarized light is experimentally demonstrated. The device, which features a nanopatterned electrode inverse‐designed by a genetic algorithm within a metal–dielectric–metal nanocavity that incorporates a vacuum‐deposited small‐molecule multilayer, exhibits ...

The weak cosmic censorship conjecture in hairy Kerr black holes

European Physical Journal C: Particles and Fields
The weak cosmic censorship conjecture, since its proposal, has always been a controversial hypothesis, but its significance in astrophysics is undeniable.
