We present a pulse timing analysis of NICER observations of the accreting millisecond X-ray pulsar SAX J1808.4−3658 during the outburst that started on 2022 August 19.

A massive millisecond pulsar in an eccentric binary [PDF]
The recent discovery of a population of eccentric (e ~ 0.1) millisecond pulsar (MSP) binaries with low-mass white dwarf companions in the Galactic field represents a challenge to evolutionary models that explain MSP formation as recycling: all such ...

XMM‐Newton Observations of the Peculiar Be X‐Ray Binary A0538‐66
ABSTRACT A0538‐66 is a neutron star/Be x‐ray binary located in the Large Magellanic Cloud and, since its discovery in the 70s, it showed a peculiar behavior that makes it a unique object in the high‐mass x‐ray binaries scene: the extremely eccentric orbit (e=0.72$$ e=0.72 $$), the short spin period of the neutron star (P=69$$ P=69 $$ ms), the episodes ...

The XinJiang Astronomical Observatory NSRT Pulsar Data Archive
The sensitivity of our pulsar observation system with typical integration time of 16 minutes has reached 0.4 mJy after we have upgraded the receiver cooling system of NanShan 25‐m radio telescope (NSRT) at Xinjiang Astronomical Observatory (XAO) in 2002. About 280 pulsars were observed after the upgrade.

The Role of XMM–Newton in the Investigation of Persistent BeXRBs
ABSTRACT The persistent BeXRBs are a class of high‐mass X‐ray binaries (HMXRBs), which are characterized by persistent low X‐ray luminosities (LX~1034$$ {L}_{\mathrm{X}}\sim {10}^{34} $$ erg s −1$$ {}^{-1} $$) and wide (Porb>$$ {P}_{\mathrm{orb}}> $$ 30 days), almost circular orbits. In these sources the NS is slowly rotating (with Pspin$$ {P}_{\mathrm{

Observations of Radio Magnetars with the Deep Space Network
The Deep Space Network (DSN) is a worldwide array of radio telescopes which supports NASA’s interplanetary spacecraft missions. When the DSN antennas are not communicating with spacecraft, they provide a valuable resource for performing observations of radio magnetars, searches for new pulsars at the Galactic Center, and additional pulsar‐related ...

The second millisecond pulsar [PDF]
On the principle that no celestial object is unique, the discovery of another millisecond pulsar is overdue. That reported on page 417 has an unexpected interest.

The NANOGrav 15 yr Data Set: Observations and Timing of 68 Millisecond Pulsars
We present observations and timing analyses of 68 millisecond pulsars (MSPs) comprising the 15 yr data set of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
