Heating up holography for single-trace J T ¯ $$ J\overline{T} $$ deformations by Luis Apolo, Wei Song

“…Abstract We study thermodynamic aspects of a tractable toy model of holography for extremal Kerr black holes proposed in [1]. On the gravity side, the theory can be described by the worldsheet action of string theory on a warped AdS3 background supported by NS-NS flux. …”

Dp-brane Dynamics and Thermalization in Type IIB Ben Ami-Kuperstein-Sonnenschein Models by Dariush Kaviani

“…We show that when the minimal extension is positive definite, the induced world volume metrics of type IIB rotating probe branes admit thermal horizons and Hawking temperatures despite the absence of black holes in the bulk subject to the world volume and topology of the nontrivial internal cycle wrapped by the probe. …”

Predicting Pulsars from Imbalanced Dataset with Hybrid Resampling Approach by Ernesto Lee, Furqan Rustam, Wajdi Aljedaani, Abid Ishaq, Vaibhav Rupapara, Imran Ashraf

“…Pulsar stars are considered an important cosmic phenomenon, and scientists use them to study nuclear physics, gravitational waves, and collisions between black holes. Defining the process of automatic detection of pulsar stars can accelerate the study of pulsar stars by scientists. …”

Linear Bending Wave Propagation in Laminar and Turbulent Disks by Callum W. Fairbairn

“…This may have implications for the inclination damping rates induced by planet–disk interactions, the capture rate of black holes in active galactic nucleus disks or the warped shapes assumed by disks in misaligned systems.…”

Une transition économique inattendue : vers le « cupidalisme » ? by Wladimir Andreff

“…Originating in post-communist economies in transition asset grabbing has spread throughout the global economy through public assets transferred to private owners (privatisations), predatory real assets stripping by finance, the emergence of shadow finance (of which shadow banking), namely in all the black holes of global finance (tax and judiciary havens). …”

Measurement of Atmospheric Neutrino Cross-Sections on Oxygen, Water and Argon using Nuwro Event Generator by Iflah Rasool Shaik, Qudsia Gani, Mir Hameeda

Revisiting the trading activity of high-frequency trading firms around ultra-fast flash events by Christophe Desagre, Floris Laly, Mikael Petitjean

“…Abstract We investigate high-frequency traders’ behavior in the context of the fastest and most extreme price movements (EPMs) that can be observed in the market, specifically ultra-fast flash events, challenging the methodologies employed in the academic and practitioner literature for identifying sudden liquidity black holes. To refine the price-shock identification methodology, we introduce a new approach called sequence-based flash events (SFEs), which relies on tick sequences instead of predetermined fixed-time intervals within which all flash events in the sample are assumed to occur. …”

A Semi-analytical Model for Stellar Evolution in AGN Disks by Alexander J. Dittmann, Matteo Cantiello

“…Disks of gas accreting onto supermassive black holes may host numerous stellar-mass objects, formed within the disk or captured from a nuclear star cluster. …”

What Drives the H i Content of Central Galaxies—A Comparison between Hydrodynamic Simulations and Observations Using Random Forest by Xiao Li, Cheng Li, H. J. Mo

“…Beyond that, the accretion rate of supermassive black holes is the most important feature in TNG, while specific star formation rate is the top ranked in EAGLE. …”

Assessing the Dark Matter Content of Two Quasar Host Galaxies at z ∼ 6 through Gas Kinematics by Qinyue Fei, John D. Silverman, Seiji Fujimoto, Ran Wang, Luis C. Ho, Manuela Bischetti, Stefano Carniani, Michele Ginolfi, Gareth Jones, Roberto Maiolino, Wiphu Rujopakarn, N. M. Förster Schreiber, Juan M. Espejo Salcedo, L. L. Lee

“…Notably, while the masses of these supermassive black holes (SMBHs) are approximately 1 dex higher than the low-redshift relationship with stellar mass, the closer alignment of SMBH and halo masses with a local relationship may indicate that the early formation of these SMBHs is linked to their dark matter halos, providing insights into the coevolution of galaxies and black holes in the early Universe.…”

Extreme Scale Height Variations and Nozzle Shocks in Warped Disks by Nicholas Kaaz, Yoram Lithwick, Matthew Liska, Alexander Tchekhovskoy
