Evidence of TeV halos around millisecond pulsars [PDF]
Physical Review D, 2021 Using data from the HAWC gamma-ray Telescope, we have studied a sample of 37 millisecond pulsars (MSPs), selected for their spindown power and proximity. From among these MSP, we have identified four which favor the presence of very high-energy gamma-ray

NICER Detection of Thermal X-Ray Pulsations from the Massive Millisecond Pulsars PSR J0740+6620 and PSR J1614–2230 [PDF]
Astrophysical Journal Letters, 2021 We report the detection of X-ray pulsations from the rotation-powered millisecond-period pulsars PSR J0740+6620 and PSR J1614−2230, two of the most massive neutron stars known, using observations with the Neutron Star Interior Composition Explorer (NICER)

Measurements of pulse jitter and single-pulse variability in millisecond pulsars using MeerKAT [PDF]
, 2021 Using the state-of-the-art SKA precursor, the MeerKAT radio telescope, we explore the limits to precision pulsar timing of millisecond pulsars achievable due to pulse stochasticity (jitter).

Spin Equilibrium of Rapidly Spinning Neutron Stars via Transient Accretion
Galaxies, 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 ...

The Emission Physics of Millisecond Pulsars [PDF]
, 2021 Understanding the physics of rotation-powered millisecond pulsars (MSPs) presents a number of challenges compared to that of the non-recycled pulsar population.

Millisecond pulsar velocities [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We present improved timing parameters for 13 millisecond pulsars (MSPs), including nine new proper motion measurements. These new proper motions bring to 23 the number of MSPs with measured transverse velocities. In light of these new results we present and compare the kinematic properties of MSPs with those of ordinary pulsars.

SAX J1808.4-3657 in Quiescence: A Keystone for Neutron Star Science [PDF]
, 2007 The accreting millisecond pulsar SAX J1808.4-3658 may be a transition object between accreting X-ray binaries and millisecond radio pulsars. We have constrained the thermal radiation from its surface through XMM-Newton X-ray observations, providing ...

The 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 ...

Description and Application of the Surfing Effect
Universe, 2022 The standard technique for very low-frequency gravitational wave detection is mainly based on searching for a specific spatial correlation in the variation of the times of arrival of the radio pulses emitted by millisecond pulsars with respect to a ...

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