A Massive Pulsar in a Compact Relativistic Binary
Introduction Neutron stars with masses above 1.8 solar masses (M☉), possess extreme gravitational fields, which may give rise to phenomena outside general relativity. These strong-field deviationsExpand
A Radio Pulsar/X-ray Binary Link
From X-ray Binary to Pulsar Pulsars with millisecond rotational periods are thought to originate from neutron stars in low-mass x-ray binaries that had their spin frequencies increased byExpand
A repeating fast radio burst
These repeat bursts with high dispersion measure and variable spectra specifically seen from the direction of FRB 121102 support an origin in a young, highly magnetized, extragalactic neutron star. Expand
The Parkes multi-beam pulsar survey - I. Observing and data analysis systems, discovery and timing of 100 pulsars
limiting flux density of the survey is about 0.2 mJy. At shorter or longer periods or higher dispersions, the sensitivity is reduced. Timing observations are carried out for pulsars discovered in theExpand
A Radio Pulsar Spinning at 716 Hz
A 716-hertz eclipsing binary radio pulsar in the globular cluster Terzan 5 using the Green Bank Telescope is discovered, it is the fastest spinning neutron star found to date, and constrains models that suggest that gravitational radiation, through an r-mode (Rossby wave) instability, limits the maximum spin frequency of neutron stars. Expand
Fast Radio Burst Discovered in the Arecibo Pulsar ALFA Survey
Recent work has exploited pulsar survey data to identify temporally isolated, millisecond-duration radio bursts with large dispersion measures (DMs). These bursts have been interpreted as arisingExpand
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)Expand
Tests of General Relativity from Timing the Double Pulsar
By measuring relativistic corrections to the Keplerian description of the orbital motion, it is found that the “post-Keplerian” parameter s agrees with the value predicted by general relativity within an uncertainty of 0.05%, the most precise test yet obtained. Expand
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,Expand
The Parkes Multibeam Pulsar Survey - VI. Discovery and timing of 142 pulsars and a Galactic population analysis
We present the discovery and follow-up observations of 142 pulsars found in the Parkes 20-cm multibeam pulsar survey of the Galactic plane. These new discoveries bring the total number of pulsarsExpand
