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 ...

Multi-Messenger Astrophysics of a Millisecond Pulsar Orbiting around a Massive Black Hole
Universe, 2022 Extreme-mass-ratio and intermediate-mass-ratio binaries with a millisecond pulsar are gravitational-wave sources that emit also electromagnetic radiation.

Stellar Forensics II: Millisecond Pulsar Binaries [PDF]
, 1997 We use the grid of models described in paper~I to analyse those millisecond pulsar binaries whose secondaries have been studied optically. In particular, we find cooling ages for these binary systems that range from $< 1 \rm Gyr$ to $\sim \rm 15 Gyr ...

Strong Support for the Millisecond Pulsar Origin of the Galactic Center GeV Excess. [PDF]
Physical Review Letters, 2015 Using γ-ray data from the Fermi Large Area Telescope, various groups have identified a clear excess emission in the Inner Galaxy, at energies around a few GeV. This excess resembles remarkably well a signal from dark-matter annihilation.

The Associations Between Chronic Active Lesions and White Matter Disease: A 7 Tesla Imaging Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background The relationship between paramagnetic rim lesions (PRLs) and surrounding normally appearing white matter (NAWM) disease, potentially contributory to the associations seen between PRLs and clinical impairment, is underexplored. Objectives To assess whether PRLs correlate with a greater degree of NAWM injury in early MS.

, 2009 We have shown previously that many of the properties of persistent accretion-powered millisecond pulsars can be understood if their X-ray emitting areas are near their spin axes and move as the accretion rate and structure of the inner disk vary. Here we

Binary-Binary Interactions and the Formation of the PSR B1620-26 Triple System in M4 [PDF]
, 1994 The hierarchical triple system containing the millisecond pulsar PSR B1620-26 in M4 is the first triple star system ever detected in a globular cluster. Such systems should form in globular clusters as a result of dynamical interactions between binaries.

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

The Relationships between Emission Geometry and Jitter Noise in Millisecond Pulsars
The Astrophysical JournalThe relationships between several parameters of an emission geometry and jitter noise in 17 millisecond pulsars (MSPs) are investigated. By assuming the jitter noise is due only to a pulse variation in phase, the former can be modeled as changes in the ...
