Effect of laser type on hole machining of SiC/SiC composites

open access: yesJournal of Aeronautical Materials, 2023
SiC/SiC composites have the characteristics of high hardness and brittleness, and they are typical difficult materials to process. Laser processing is mainly used to prepare cooling holes.

The Effect of Irradiation on the Spin of Millisecond Pulsars

open access: yesThe Astrophysical Journal Letters, 2023
A millisecond pulsar (MSP) is an old neutron star (NS) that has accreted material from its companion star, causing it to spin up, which is known as the recycling scenario.

Discovery and Timing Analysis of New Pulsars in Globular Cluster NGC 5024: New Observations from FAST

open access: yesThe Astrophysical Journal Letters, 2023
The most distant globular cluster (GC) with known pulsars is NGC 5024 (M53). In this paper, we report the discovery of a new binary millisecond pulsar, PSR J1312+1810E (M53E), and present the new timing solutions for M53B–E based on 22 observations from ...

Comparing random dot motion in MATLAB vs. Inquisit Millisecond

open access: yesFrontiers in Psychology, 2022
Random Dot Motion (RDM) displays refer to clouds of independently moving dots that can be parametrically manipulated to provide a perception of the overall cloud moving coherently in a specified direction of motion.

A NICER View of the Nearest and Brightest Millisecond Pulsar: PSR J0437–4715 [PDF]

open access: yesAstrophysical Journal Letters
We report Bayesian inference of the mass, radius, and hot X-ray emitting region properties—using data from the Neutron Star Interior Composition ExploreR (NICER)—for the brightest rotation-powered millisecond X-ray pulsar, PSR J0437−4715. Our modeling is

The Galactic Millisecond Pulsar Population [PDF]

open access: yes, 2012
Among the current sample of over 2000 radio pulsars known primarily in the disk of our Galaxy, millisecond pulsars now number almost 200. Due to the phenomenal success of blind surveys of the Galactic field, and targeted searches of Fermi gamma-ray ...

Gravitational-wave Constraints on the Equatorial Ellipticity of Millisecond Pulsars [PDF]

open access: yesAstrophysical Journal Letters, 2020
We present a search for continuous gravitational waves from five radio pulsars, comprising three recycled pulsars (PSR J0437−4715, PSR J0711−6830, and PSR J0737−3039A) and two young pulsars: the Crab pulsar (J0534+2200) and the Vela pulsar (J0835−4510 ...
