Relativistic Shapiro delay measurements of an extremely massive millisecond pulsar
Despite its importance to our understanding of physics at supranuclear densities, the equation of state (EoS) of matter deep within neutron stars remains poorly understood. Millisecond pulsars (MSPs)
Multifrequency Observations of Radio Pulse Broadening and Constraints on Interstellar Electron Density Microstructure
We have made observations of 98 low Galactic latitude pulsars to measure pulse broadening caused by multipath propagation through the interstellar medium. Data were collected with the 305 m Arecibo
The NANOGrav Nine-year Data Set: Mass and Geometric Measurements of Binary Millisecond Pulsars
We analyze 24 binary radio pulsars in the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) nine-year data set. We make fourteen significant measurements of Shapiro delay,
A 2.1 M☉ Pulsar Measured by Relativistic Orbital Decay
PSR J0751+1807 is a millisecond pulsar in a circular 6 hr binary system with a helium white dwarf secondary. Through high-precision pulse timing measurements with the Arecibo and Effelsberg radio
Timing Measurements of the Relativistic Binary Pulsar PSR B1913+16
We present results of more than three decades of timing measurements of the first known binary pulsar, PSR B1913+16. Like most other pulsars, its rotational behavior over such long timescales is
Timing behavior of 96 radio pulsars
We present results from observations of 104 pulsars made between 1989 August and 1993 April, including timing solutions for 96 of them. Pulse profiles were recorded at four frequencies in the range
An Eccentric Binary Millisecond Pulsar in the Galactic Plane
TLDR
In a survey with the Arecibo telescope, a radio pulsar with a rotational period of 2.15 milliseconds in a highly eccentric orbit around a solar mass is found and infrared observations identify a possible main-sequence companion star.
The NANOGrav 12.5 yr Data Set: Search for an Isotropic Stochastic Gravitational-wave Background
We search for an isotropic stochastic gravitational-wave background (GWB) in the $12.5$-year pulsar timing data set collected by the North American Nanohertz Observatory for Gravitational Waves
On the nature and evolution of the unique binary pulsar J1903+0327
PSR J1903+0327, a millisecond pulsar in an eccentric (e = 0.44) 95-d orbit with an ∼ 1M � companion poses a challenge to our understanding of stellar evolution in binary and multiplestar systems.
