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 deviations…
Masses, Radii, and the Equation of State of Neutron Stars
We summarize our current knowledge of neutron-star masses and radii. Recent instrumentation and computational advances have resulted in a rapid increase in the discovery rate and precise timing of…
THE SECOND FERMI LARGE AREA TELESCOPE CATALOG OF GAMMA-RAY PULSARS

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.
A Double-Pulsar System: A Rare Laboratory for Relativistic Gravity and Plasma Physics
The detection of the 2.8-second pulsar J0737–3039B as the companion to the 23-millisecond pulsars in a highly relativistic double neutron star system, allowing unprecedented tests of fundamental gravitational physics.
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.

The dramatic increase in the number of known gamma-ray pulsars since the launch of the Fermi Gamma-ray Space Telescope (formerly GLAST) offers the first opportunity to study a sizable population of…
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.
FAST RADIO BURST DISCOVERED IN THE ARECIBO PULSAR ALFA SURVEY
- L. Spitler, J. Cordes, H. Fehrmann
- Physics
- 10 April 2014
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 arising…
A strong magnetic field around the supermassive black hole at the centre of the Galaxy

- PhysicsNature
- 14 August 2013
Multi-frequency radio measurements of a newly discovered pulsar close to the Galactic Centre are reported and it is shown that the pulsar’s unusually large Faraday rotation indicates that there is a dynamically important magnetic field near the black hole.
