Pulse profiles of millisecond pulsars [PDF]
International Astronomical Union Colloquium, 1996 We present a comparison between the average radio pulse profiles of millisecond pulsars (MSPs) in the field and in globular clusters. Our sample consists of 20 field MSPs and 25 cluster MSPs for which observations exist at 400 - 600 MHz. We find that 6 of the 20 field MSPs, or about 30%, have a comparable interpulse at a phase offset of 180 ±30 ...

Discovery of Millisecond Pulsars in the Globular Cluster Omega Centauri [PDF]
Astrophysical Journal, 2019 The globular cluster Omega Centauri is the most massive and luminous cluster in the Galaxy. The γ-ray source FL8Y J1326.7–4729 is coincident with the core of the cluster, leading to speculation that hitherto unknown radio pulsars or annihilating dark ...

An ultraluminous nascent millisecond pulsar [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2015 Abstract If the ultraluminous source (ULX) M82 X-2 sustains its measured spin-up value of $\dot{\nu }= 10^{-10}\,{\rm s^{-2}}$, it will become a millisecond pulsar in less than 105 yr. The observed (isotropic) luminosity of 1040 erg s−1 also supports the notion that the neutron star will spin up to a millisecond period upon accreting ...

Super-Massive Neutron Stars and Compact Binary Millisecond Pulsars [PDF]
Proceedings of Multifrequency Behaviour of High Energy Cosmic Sources - XIII — PoS(MULTIF2019), 2019 The maximum mass of a neutron star has important implications across multiple research fields, including astrophysics, nuclear physics and gravitational wave astronomy.

Highlights of Astronomy, 1989 AbstractMillisecond pulsars are intrinsically interesting because they illustrate some of the most extreme physical conditions to be found anywhere in the Universe, and because their evolution exhibits several stages of great drama. It had been widely believed for several years that spin-up of an old neutron star by accretion from a close stellar ...

Eight Millisecond Pulsars Discovered in the Arecibo PALFA Survey [PDF]
Astrophysical Journal, 2019 We report on eight millisecond pulsars (MSPs) in binary systems discovered with the Arecibo L-Band Feed Array (PALFA) pulsar survey. Phase-coherent timing solutions derived from 2.5–5 yr of observations carried out at the Arecibo and Jodrell Bank ...

Evidence for a Minimum Ellipticity in Millisecond Pulsars [PDF]
Astrophysical Journal, 2018 Neutron stars spin down over time due to a number of energy-loss processes. We provide tantalizing population-based evidence that millisecond pulsars (MSPs) have a minimum ellipticity of ϵ ≈ 10−9 around their spin axis and that, consequently, some spin ...

Bayesian model comparison and analysis of the Galactic disc population of gamma-ray millisecond pulsars [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Pulsed emission from almost one hundred millisecond pulsars (MSPs) has been detected in γ-rays by the Fermi Large-Area Telescope. The global properties of this population remain relatively unconstrained despite many attempts to model their spatial and ...
