Astrophysics in 1995 [PDF]

Publications of the Astronomical Society of the Pacific, 1996
Ap95 differs from Ap91 to Ap94 primarily in Ap number. That is, it once again attempts to highlight some areas of our mutual science where a major event has occurred during the year (a possible solution of the Type II supernova problem, the faintness of quasar host galaxies, and the collision of Shoemaker-Levy 9 with Jupiter), but also to focus on some

Artificial Intelligence‐Assisted Target Design for High‐Intensity Laser‐Driven Neutron Sources

Advanced Intelligent Systems, EarlyView.
This study presents an artificial intelligence (AI)‐assisted target design that combines particle‐in‐cell simulations with gradient ascent algorithm to optimize laser‐driven neutron sources. By enhancing the sheath electric field, the optimized structure increases neutron yield by a factor of 4,000.

Astrophysics in 1996 [PDF]

Publications of the Astronomical Society of the Pacific, 1997
The loudest astronomical headlines of the year came from both very near (planets orbiting stars in the solar neighborhood) and very far (galaxies and parts of galaxies at redshifts of 1 to 3 and more). We explore these and other happenings in our Solar System (Galileo at Jupiter, Comet Hyakutake), Milky Way (the bursting pulsar, spotted stars), Local ...

The visual, the textual, and the one‐dimensional: An exploration of the visual elements of bibliographic classification schemes

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Classification schemes are a key way of organizing bibliographic knowledge, yet the way that classification schemes communicate their information to classifiers receives little attention. This article takes a novel approach by exploring the visual aspects contained within classification schemes.

Improved effective-one-body model of spinning, nonprecessing binary black holes for the era of gravitational-wave astrophysics with advanced detectors [PDF]

, 2016
We improve the accuracy of the effective-one-body (EOB) waveforms that were employed during the first observing run of Advanced LIGO for binaries of spinning, nonprecessing black holes by calibrating them to a set of 141 numerical-relativity (NR ...

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

Astronomische Nachrichten, EarlyView.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Multimessenger Studies with the Pierre Auger Observatory

Particles
The Pierre Auger Observatory, the world’s largest ultra-high-energy (UHE) cosmic ray (CR) detector, plays a crucial role in multi-messenger astroparticle physics with its high sensitivity to UHE photons and neutrinos.

Origin of an orbiting star around the galactic supermassive black hole

Proceedings of the Japan Academy. Series B, Physical and Biological Sciences, 2023
The tremendous tidal force that is linked to the supermassive black hole (SMBH) at the center of our galaxy is expected to strongly subdue star formation in its vicinity.

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

Astronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

The Euler’s harmonic holomorphic regenerative universe [PDF]

INCAS Bulletin
The Cartesian dualism is a precursor to Euler’s complex theory, that completes the Descartes-Leibnitz monadic conception using the natural quanta (non-splitting e, π) along with their topological torsion in the form of dual isomorphism.
