Correct Criterion of Crustal Failure Driven by Intense Magnetic Stress in Neutron Stars

Magnetar outbursts are powered by an intense magnetic field. The phenomenon has recently drawn significant attention because of a connection to some fast radio bursts that has been reported. Understanding magnetar outbursts may provide the ...

A tetraquark 81-plet with $$J^{PC}=1^{-+}$$ J PC = 1 - + or a hybrid nonet

Abstract Confirming the existence of hybrid states remains challenging due to their experimental indistinguishability from tightly bound tetraquarks and loosely bound molecules. To address this issue, we employ QCD sum rules to systematical...

A Gaussian Process Framework for Testing General Relativity with Gravitational Waves

Gravitational-wave astronomy provides a promising avenue for the discovery of new physics beyond general relativity as it probes extreme curvature and ultrarelativistic dynamics. However, in the absence of a compelling alternative to genera...

Multiplexed quantum repeaters based on single-photon interference with mild stabilization

Abstract Quantum repeaters are pivotal in the physical layer of the quantum internet, and quantum repeaters capable of efficient entanglement distribution are necessary for its development. Quantum repeater schemes based on single-photon in...

The Be star o Cas is indeed the primary of a triple system

Analysis of radial velocities of two narrow absorption components in the Mg II 4481 Å line demonstrated that the secondary of the Be star o Cas is indeed a close binary system composed of two B7 stars orbiting each other with a period of ...

Cross-correlation transmission spectroscopy of ultra-hot Jupiters WASP-189b, HAT-P-57b, KELT-17b, and KELT-21b with GIANO-B

Since the discovery of the first exoplanet, significant efforts have been made to characterise their atmospheres. Ultra-hot Jupiters (UHJs) are of particular interest due to their extended and hot atmospheres. Although previous studies have...

Investigating the timelike Compton scattering in photon–proton interactions at the EIC

Abstract Information about the three-dimensional description of the quark and gluon content of hadrons, described by the generalized parton distributions (GPDs), can be probed by exclusive processes in electron–proton (ep) collisions. In th...

27 yr of Spaceborne IR Astronomy: An ISO, Spitzer, WISE, and NEOWISE Survey for Large-amplitude Variability in Young Stellar Objects

Infrared observations can probe photometric variability across the full evolutionary range of young stellar objects (YSOs), from deeply embedded protostars to pre-main-sequence stars with dusty disks. We present 3–8 μ m light curves extendi...

Constraining young massive cluster properties with radio-continuum observations: The Arches cluster

Context. The Arches cluster, located in the Galactic Centre (GC) is one of the best astrophysical laboratories to study the properties of massive stars and young massive clusters (YMCs). However, despite having been observed for decades at ...

Cusp of Non-Gaussian Density of Particles for a Diffusing Diffusivity Model

We study a two state “jumping diffusivity” model for a Brownian process alternating between two different diffusion constants, D+>D−, with random waiting times in both states whose distribution is rather general. In the limit of long measur...

DPS mechanism for associated $$c\bar{c} b\bar{b}$$ cc¯bb¯ production in AA UPCs

Abstract We discuss the associated $$c\bar{c}$$ cc¯ and $$b\bar{b}$$ bb¯ quark pairs production in the double-parton scattering (DPS) process in ultraperipheral (UPCs) AA collisions. We derive an analogue of the inclusive DPS pocket formula...

Yang–Mills black holes in quasitopological gravity

Abstract In this paper, we formulate two new classes of black hole solutions in higher curvature quartic quasitopological gravity with nonabelian Yang–Mills theory. At first step, we consider the SO(n) and $$SO(n-1,1)$$ S O ( n - 1 , 1 ) se...

The magnetic fields in Be stars are stronger than previously suggested

Context. Recent observational studies suggest that Be stars most likely are formed through the process of mass transfer in binary systems. In view of the wide consensus that the origin of the magnetic field in stars with radiative envelopes...

Power Load Probabilistic Prediction Based on Multi-Value Quantile Regression and Timing Fusion Ensemble Learning Model

The core component to ensure the refined and safe operation of distribution network scheduling is 10 kV bus load probabilistic prediction. However, existing probabilistic prediction methods suffer from insufficient dynamic feature extractio...

On the Anisotropic Velocity Distribution of Newborn Pickup Ions in the Heliosheath

The evolution of the velocity distribution of pickup ions is crucial for understanding the energetic neutral atom (ENA) fluxes observed by Interstellar Boundary Explorer. Pickup ions in the heliosheath contain two main components: those tra...

FEAST: JWST Uncovers the Emerging Timescales of Young Star Clusters in M83

We present JWST NIRCam observations of the emerging young star clusters (eYSCs) detected in the nearby spiral galaxy M83. The NIRcam mosaic encompasses the nuclear starburst, the bar, and the inner spiral arms. The eYSCs, detected in Pa α a...

Particle astrophysics with high energy neutrinos

High-Energy Neutrino Astrophysics

▪ Abstract High-energy (>100 MeV) neutrino astrophysics enters an era of opportunity and discovery as the sensitivity of detectors approaches astrophysically relevant flux levels. We review the major challenges for this emerging field, amon...

Astrophysics of Dust

Abstract. Currently ∼36 different absorption bands have been detected in the infrared spectra of cold, dense interstellar and circumstellar environments. These are attributed to the vibrational transitions of ∼17 different molecules frozen ...

Numerical Relativity and Astrophysics

Throughout the Universe many powerful events are driven by strong gravitational effects that require general relativity to fully describe them. These include compact binary mergers, black hole accretion, and stellar collapse, where velociti...
