A 350 MHz Green Bank Telescope Survey of Unassociated Fermi LAT Sources: Discovery and Timing of 10 Millisecond Pulsars

The Astrophysical Journal
We have searched for radio pulsations toward 49 Fermi Large Area Telescope (LAT) 1FGL Catalog γ -ray sources using the Green Bank Telescope at 350 MHz. We detected 18 millisecond pulsars (MSPs) in blind searches of the data; 10 of these were discoveries ...

Polarized Multiwavelength Emission from Pulsar Wind—Accretion Disk Interaction in a Transitional Millisecond Pulsar

The Astrophysical Journal Letters
Transitional millisecond pulsars (tMSPs) bridge the evolutionary gap between accreting neutron stars in low-mass X-ray binaries and millisecond radio pulsars.

A Counterintuitive Correlation between Neutron Star Radii Inferred from Pulse Modeling and Surface Emission Beaming

The Astrophysical Journal
Thermal X-ray emission from rotation-powered millisecond pulsars, shaped by gravitational lensing and the beaming of the surface radiation, provides critical insights into neutron star properties. This approach has been the focus of observations with the

Transient Emission Phenomena in Millisecond Pulsars [PDF]

Millisecond pulsars are rapidly rotating neutron stars, with rotational periods on the order of milliseconds. The radio emission of millisecond pulsars exhibit a variety of interesting features such as bright transient bursts and rapid state changes ...
