The Crucial First Step in the Discovery of Millisecond Pulsars [PDF]
arXivMillisecond pulsars, like pulsars, have led to major advances in many areas of astronomy and physics. The discovery in 2023 of a cosmological gravitational wave (GW) stochastic background using millisecond pulsar timing arrays has focused attention on the importance of millisecond pulsars, to both multi-messenger astronomy and cosmology, and for ...

Spin Rates and Magnetic Fields of Millisecond Pulsars [PDF]
arXiv, 2004 Observations made using the Rossi X-ray Timing Explorer have shown that accreting weak-field neutron stars in low-mass X-ray binary systems (LMXBs) produce three distinct types of millisecond X-ray oscillations that can be used to determine the spin rates and estimate the magnetic fields of these stars.

Advanced Materials, EarlyView.This study introduces a multimodal nonlinear microscopy approach using upconverting nanoparticles (UCNPs) under continuous‐wave excitation. The UCNPs exhibit high‐order nonlinear optical responses, enabling deep‐tissue 3D imaging, video‐rate wide‐field imaging, and depth‐selective photomodulation.

Millisecond pulsar population in the Galactic center and high energy contributions [PDF]
arXiv, 2005 We propose that there possibly exists a population of millisecond pulsars in the Galactic center region. Millisecond pulsars (MSPs) could emit GeV gamma-rays through synchrotron-curvature radiation as predicted by outer gap models. In the same time, the compact wind nebulae around millisecond pulsars can emit X-rays though synchrotron radiation and TeV

3D Wiring Microelectrodes in a PMMA Microfluidic Device by Vacuum Filling Method
Advanced Materials Technologies, EarlyView.This paper proposes a method for fabricating 3D wiring microelectrodes in arbitrary designs within 3D‐printed microfluidics. By attaching a PDMS lid and using vacuum filling, low‐melting‐point alloy (LMA) is introduced into microchannels. This enables the creation of 50 µm microelectrodes, including complex shapes.
