Swings between rotation and accretion power in a millisecond binary pulsar [PDF]

open access: yesThe Astrophysical Journal Letters, 2013
It is thought that neutron stars in low-mass binary systems can accrete matter and angular momentum from the companion star and be spun-up to millisecond rotational periods.

Gamma-ray emission from millisecond pulsars - an Outergap perspective [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2013
In this review paper we explain the following gamma-ray emission features from the millisecond pulsars. (1) Why is the dipolar field of millisecond pulsars so weak but the magnetic pair creation process may still be able to control the size of the ...

Une perception discrète ? Et le sens de la continuité du temps, alors ?

open access: yesRecherches, 2021
Individuals with disorders on the schizophrenia spectrum report temporal thought fragmentation and of their bodily sense of self. These clinical descriptions question the mechanisms that enable a sense of continuity of time, and a sense of immersion in ...

Exploring Frontiers of 4D X-ray Tomography

open access: yesApplied Sciences, 2021
In the 4D world of three-dimensional (3D) space plus time that we live in, there is a vast blue ocean in the spatio-temporal domain of micrometers and milliseconds that has never been accessed even with the most advanced measurement technology, and it is

Spin Equilibrium of Rapidly Spinning Neutron Stars via Transient Accretion

open access: yesGalaxies, 2023
The concept of spin equilibrium due to an interaction between the stellar magnetosphere and a thin, Keplerian accretion disk, and a well-known formula of the corresponding equilibrium spin frequency, provide a key understanding of spin evolution and the ...

Search for the Gravitational-wave Background from Cosmic Strings with the Parkes Pulsar Timing Array Second Data Release

open access: yesThe Astrophysical Journal, 2022
We perform a direct search for an isotropic stochastic gravitational-wave background (SGWB) produced by cosmic strings in the Parkes Pulsar Timing Array (PPTA) Data Release 2 (DR2).

Electroporation safety factor of 300 nanosecond and 10 millisecond defibrillation in Langendorff-perfused rabbit hearts.

open access: yesPLoS ONE, 2021
AimsRecently, a new defibrillation modality using nanosecond pulses was shown to be effective at much lower energies than conventional 10 millisecond monophasic shocks in ex vivo experiments.

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.
