Polarized X-Rays Detected from the Anomalous X-Ray Pulsar 1E 2259+586

The Astrophysical Journal
Anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are believed to be associated with magnetars, which have extremely strong magnetic fields.

A strongly magnetized strange star model for soft gamma-ray repeaters

, 2002
Soft γ-ray repeaters (SGRs) have been currently argued as super-strongly magnetized neutron stars (magnetars) with magnetic fields with a few 1014 G. Here we propose an alternate model, in which SGRs are young strange stars with superconducting cores and

Additive Manufacturing of High‐Performance Polymers for Extreme Environments

Advanced Science, EarlyView.
Additive manufacturing of high‐performance polymers for extreme environments is critically reviewed through an integrated chemistry‐processing‐structure‐property‐qualification framework. The review compares fused filament fabrication, selective laser sintering, and direct ink writing, linking rheology and thermal history to crystallization, defect ...

17 yr of Magnetar Bursts Observed with the Fermi Gamma-Ray Burst Monitor

The Astrophysical Journal Supplement Series
The Fermi Gamma-ray Burst Monitor (GBM) has been in operation for over 17 yr, during which it has observed more than 1000 bursts from soft gamma repeaters (SGRs), also known as magnetars.

Scalable Multilayer PTFE‐Reinforced Membranes for Durable, High‐Current‐Density Hydroxide Exchange Membrane Water Electrolysis in Dilute Alkali

Advanced Science, EarlyView.
Low‐Tg HEMs are designed to improve membrane‐electrode adhesion by promoting intimate contact with catalyst layers. After hydration, the membrane develops a hydrogel‐like network that supports water uptake and ion transport while retaining mechanical robustness.

Nonlinear Coupling between Magnetar QPOs

The Astrophysical Journal
The quasiperiodic oscillations (QPOs) observed in the tails of magnetar giant γ -ray flares have long been interpreted as normal oscillation modes of these stars. However, most studies modeling QPOs have neglected some key features in the analyses of the

The Environments of Soft Gamma-Ray Repeaters: A Brief & Biased Review

, 2002
I review some recent developments in our understanding of the environments of soft gamma-ray repeaters. I pay particular attention to the apparent association betwwen SGR 1900+14 and SGR 1806-20 and embedded clusters of stars.

Understanding soft gamma-ray repeaters in the context of the extragalactic radio pulsar origin of gamma-ray bursts

The Astrophysical Journal, 1993
Gamma-ray burst (GRB) sources and soft gamma-ray repeaters (SGRs) may be neutron stars undergoing structural adjustments that produce transient gamma-ray events. A unified scenario is proposed in which young radio pulsars are responsible for SGRs and classical GRB sources.
