Interfaces in Numerical Relativistic hydrodynamics [PDF]
, 2010 This thesis investigates numerical techniques for modelling sharp interfacesbetween relativistic fluids. The motivation for this work lies in obtaining accuratemodels of neutron star interiors for use in multidimensional simulationsin general relativity. Millmore, Stephen Timothycore First Look at the High-resolution X-Ray Spectra in the Highly Absorbed High-mass X-Ray Binary IGR J16318−4848 with Chandra
The Astrophysical JournalWe present a comprehensive analysis of the X-ray spectrum of the highly obscured high-mass X-ray binary IGR J16318−4848 based on ∼250 ks Chandra/HETGS observations covering different orbital phases.Pragati Pradhan, David P.

Advanced Science, EarlyView.WS2‐based in‐memory sensing reservoir computing integrates sensing, memory, and computation in one compact device. It achieves ∼94% N‐MNIST, ∼93% eye motion perception, and ∼89% speech recognition with ultra‐low energy (∼25.5 fJ/spike). The system shows stability at 95% humidity, endurance over 1.5M cycles, and supports synaptic plasticity, enabling ...Dayanand Kumar, Hanrui Li, Divyanshu Divyanshu, Dhananjay D.

The Astrophysical Journal LettersThe X-ray binary system Cygnus X-3 (4U 2030+40, V1521 Cyg) is luminous but enigmatic owing to the high intervening absorption. High-resolution X-ray spectroscopy uniquely probes the dynamics of the photoionized gas in the system.XRISM Collaboration, Marc Audard, Hisamitsu Awaki, Ralf Ballhausen, Aya Bamba, Ehud Behar, Rozenn Boissay-Malaquin, Laura Brenneman, Gregory V.

Advanced Science, EarlyView.This study integrates two complementary traditional Chinese medicine components as precursors to synthesize bioactive AM‐AS@CDs. Compared with single‐component CDs, these dual‐component CDs exhibit enhanced antioxidant capacity and superior renoprotective effects.Bixiao Liu, Fuying Zhu, Zhuqing Wang, Jiawen Chen, Xiaomiao Cui, Congzhong Yang, Yao Peng, Dengyuan Feng, Li Lu, Hui Wei, Xiaozhi Zhao +10 morewiley +1 more sourceRelativistic Scattering in the Funnel of Cygnus X-3
The Astrophysical JournalCygnus X-3 presents significant challenges to standard accretion models. Recent polarimetric observations by X-ray Polarimetry Explorer reveal high polarization degrees in the hard state (∼23%) and unexpectedly significant polarization in the soft state (Suraj K.

Advanced Science, EarlyView.This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.Maoyuan Huang, Ziqiang Tian, Binkun Xie, Haiyang Li, Bo Tan, Chang He, Shiliang Mei, Wanlu Zhang, Changchun Wang, Ruiqian Guo +9 morewiley +1 more sourceX-ray diversity in old star clusters [PDF]
, 2018 The X-ray sky is host to a variety of objects with very distinct properties and underlying physics. In particular, groups of stars known as star clusters are excellent environments to study an array of X-ray sources.Vats, S.core The CHARA Array Interferometric Program on the Multiplicity of Classical Be Stars: New Detections and Orbits of Stripped Subdwarf Companions
The Astrophysical JournalRapid rotation and nonradial pulsations enable Be stars to build decretion disks, where the characteristic line emission forms. A major but unconstrained fraction of Be stars owe their rapid rotation to mass and angular momentum transfer in a binary. The Robert Klement, Thomas Rivinius, Douglas R.
