Constraints on the Cosmological Coupling of Black Holes from the Globular Cluster NGC 3201

The Astrophysical Journal Letters, 2023
Globular clusters are among the oldest stellar populations in the Milky Way; consequently, they also host some of the oldest known stellar-mass black holes, providing insight into black hole formation and evolution in the early ( z ≳ 2) universe.

Clusters of Primordial Black Holes [PDF]

The European Physical Journal C, 2018
The Primordial Black Holes (PBHs) are a well-established probe for new physics in the very early Universe. We discuss here the possibility of PBH agglomeration into clusters that may have several prominent observable features.

A scalar field condensation instability of rotating anti-de Sitter black holes

, 2010
Near-extreme Reissner-Nordstrom-anti-de Sitter black holes are unstable against the condensation of an uncharged scalar field with mass close to the Breitenlohner-Freedman bound. It is shown that a similar instability afflicts near-extreme large rotating

A Multi‐Center Retrospective Cohort Study of Neurosarcoidosis Myelitis: Current Observations and Future Directions

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The optimal treatment for neurosarcoidosis myelitis is uncertain. We characterize incident neurosarcoidosis myelitis and assess treatment response by MRI and clinical scales. Methods Incident probable or definite neurosarcoidosis myelitis in adults was retrospectively identified from 13 academic medical centers.

Energy input from quasars regulates the growth and activity of black holes and their host galaxies [PDF]

Nature, 2005
In the early Universe, while galaxies were still forming, black holes as massive as a billion solar masses powered quasars. Supermassive black holes are found at the centres of most galaxies today, where their masses are related to the velocity ...

High‐Temperature Oxidation of the CrFeNi Medium‐Entropy Alloy

Advanced Engineering Materials, EarlyView.
The oxidation behavior of equiatomic CrFeNi MEA is a key issue that determines this material's suitability for high‐temperature application. The understanding of long‐term behavior is even more crucial than short‐term corrosion effects. The alloy is exposed to synthetic air at 1000, 1050, and 1100 °C for 24, 100, and 1000 h and systematically compared ...

Impact of Structural Adhesive Hybridization Strategy on the Performance of In‐Mold Electronics Devices Across Thermoforming and Injection Molding

Advanced Engineering Materials, EarlyView.
In‐mold electronics (IME) undergo complex thermoforming and over‐molding processes that strain device integrity. This study demonstrates how adapting the amount and placement of structural adhesive to local deformation levels preserves electrical functionality.

The special role of toroidal black holes in holography

Nuclear Physics B, 2023
In the standard holographic “dictionary”, the deep infrared of the strongly coupled boundary field theory is studied by examining the bulk region near to the event horizon of a simple AdS-Reissner-Nordström black hole, near to extremality.
