We report the discovery of PSR J0952$-$0607, a 707-Hz binary millisecond pulsar which is now the fastest-spinning neutron star known in the Galactic field (i.e., outside of a globular cluster). PSR J0952$-$0607 was found using LOFAR at a central observing frequency of 135 MHz, well below the 300 MHz to 3 GHz frequencies typically used in pulsar searches. The discovery is part of an ongoing LOFAR survey targeting unassociated Fermi Large Area Telescope $\gamma$-ray sources. PSR J0952$-$0607 is…

XMM-Newton Detection and Spectrum of the Second Fastest Spinning Pulsar PSR J0952−0607
With a spin frequency of 707 Hz, PSR J0952-0607 is the second fastest spinning pulsar known. It was discovered in radio by LOFAR in 2017 at an estimated distance of either 0.97 or 1.74 kpc and has a
A Millisecond Pulsar Discovery in a Survey of Unidentified Fermi γ-Ray Sources with LOFAR
Using LOFAR, we have performed a very-low-frequency (115−155 MHz) radio survey for millisecond pulsars (MSPs). The survey targeted 52 unidentified Fermi γ-ray sources. Employing a combination of
Discovery of a Steep-spectrum Low-luminosity Pulsar with the Murchison Widefield Array
We report the discovery of the first new pulsar with the Murchison Widefield Array (MWA), PSR J0036−1033, a long-period (0.9 s) nonrecycled pulsar with a dispersion measure (DM) of 23.1 pc cm−3. It
Detection and Timing of Gamma-Ray Pulsations from the 707 Hz Pulsar J0952−0607
The LOFAR radio telescope discovered the $707$-Hz binary millisecond pulsar J0952$-$0607 in a targeted radio pulsation search of an unidentified $\textit{Fermi}$ gamma-ray source. This source shows a
LOFAR radio search for single and periodic pulses from M 31
Bright, short radio bursts are emitted by sources at a large range of distances: from the nearby Crab pulsar to remote Fast Radio Bursts (FRBs). FRBs are likely to originate from distant neutron
The Search for Millisecond Pulsars – Implications from Fermi Observations and Future Prospects
Millisecond pulsars (MSPs) are old pulsars which have been spun up to incredible rotation rates by the accretion of matter from an orbiting companion star. Their extreme properties and long-term
Optical detection of the black widow binary PSR J2052+1219
We present optical time-resolved multiband photometry of the black widow binary millisecond pulsar J2052+1219 using direct-imaging observations with the 2.1-m telescope of the Observatorio
First measurement of the total gravitational quadrupole moment of a black widow companion
We present the first measurement of the gravitational quadrupole moment of the companion star of a spider pulsar, namely the black widow PSR J2051$-$0827. To this end we have re-analysed radio timing
The GBT 350-MHz Drift Scan Pulsar Survey – III. Detection of a magnetic field in the eclipsing material of PSR J2256–1024
We present the first measurement of a non-zero magnetic field in the eclipsing material of a black widow pulsar. Black widows are millisecond pulsars which are ablating their companions; therefore
The prospects of pulsar timing with new-generation radio telescopes and the Square Kilometre Array
TLDR
Present and near-future pulsar surveys, especially those using the new generation of telescopes, will find more extreme binary systems and pulsars that are more precise ‘clocks’ and the increased number of sources will reveal rare sources, including possibly a pulsar–black hole binary, which can provide the most stringent tests of strong-field gravity.

A Radio Pulsar Spinning at 716 Hz
TLDR
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.
