AN UPPER BOUND ON NEUTRON STAR MASSES FROM MODELS OF SHORT GAMMA-RAY BURSTS [PDF]

open access: yes, 2015
The discovery of two neutron stars with gravitational masses ≈ 2 M ⊙ ?> has placed a strong lower limit on the maximum mass of nonrotating neutron stars, and with it a strong constraint on the properties of cold matter beyond nuclear density.

SEARCH FOR PROMPT NEUTRINO EMISSION FROM GAMMA-RAY BURSTS WITH ICECUBE [PDF]

open access: yesAstrophysical Journal, 2014
We present constraints derived from a search of four years of IceCube data for a prompt neutrino flux from gamma-ray bursts (GRBs). A single low-significance neutrino, compatible with the atmospheric neutrino background, was found in coincidence with one

A White Dwarf Merger Paradigm for Supernovae and Gamma-Ray Bursts

open access: yes, 2003
Gamma-ray bursts can appear to be a hundred times as luminous as supernovae, but their underlying energy source(s) have remained a mystery. However, there has been evidence for some time now of an association of gamma-ray bursts with supernovae of Type ...

Thermal and Nonthermal Emission from a Peculiar Long-duration GRB 211211A

open access: yesThe Astrophysical Journal, 2023
Long-duration GRB 211211A that lacks a supernova emission even down to very stringent limits at such a low redshift z = 0.076 and is associated with kilonova emission, suggests that its physical origin is from a binary compact star merger. By reanalyzing

Carbon Fiber Reinforced Thermoplastics: From Materials to Manufacturing and Applications

open access: yesAdvanced Materials, EarlyView.
A contemporary and critical review on carbon fiber reinforced thermoplastics. The common thermoplastic and carbon fiber applied in the manufacture of carbon fiber reinforced thermoplastics are summarized, and the processing and postprocessing methods are reviewed, with emphasis on state‐of‐the‐art welding techniques.

GRB 200829A: External-shock Origin of the Very Early Prompt Emission?

open access: yesThe Astrophysical Journal, 2023
Long-duration GRB 200829A was detected by Fermi-GBM and Swift-BAT/XRT, and then rapidly observed by other ground-based telescopes. It has a weak γ -ray emission in the very early phase and is followed by a bright spiky γ -ray emission pulse.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Neutrino and cosmic-ray emission from multiple internal shocks in gamma-ray bursts [PDF]

open access: yesNature Communications, 2014
Gamma-ray bursts (GRBs) are short-lived, luminous explosions at cosmological distances, thought to originate from relativistic jets launched at the deaths of massive stars.

Adjusting Cell‐Surface Interactions Through a Covalent Immobilization of Biomolecules

open access: yesAdvanced Materials Interfaces, EarlyView.
This review presents an overview of current and emerging immobilization techniques coupled with an in‐depth investigation of the underlying mechanisms governing the activity and stability of covalently immobilized biomolecules. The aim of this study is to serve as a guide for the development of long‐lasting biomedical coatings with versatile biological
