A Candidate Open Cluster Pulsar: Timing Analysis of PSR J1922+3745 in NGC 6791

Xiao-Jin Liu, Ralph P. Eatough, Zhichen Pan +15

PSR J1922+3745 was recently identified as a radio pulsar toward the old open cluster NGC 6791, raising the prospect of the first pulsar associated with an open cluster. We report F…

Constraining the Pulsar 3D Velocity Distribution: The Impact of Spin-Velocity Alignment

Zheng Li, Xiaojin Liu, Zhi-Qiang You +2

Quantifying the natal kick distribution of pulsars is essential for understanding supernova physics and binary evolution, yet measurements are historically limited by the lack of r…

A Census of Pulsars in Possible Association with Galactic Open Clusters

Lu Zhou, Zhi-Qiang You, Lu Li +3

Among the known pulsars in our Galaxy, are found in globular clusters, but none has been confirmed in any open clusters yet, although they outnumber glo…

The birth mass function of neutron stars

Zhi-Qiang You, Xingjiang Zhu, Xiaojin Liu +12

The birth mass function of neutron stars encodes rich information about supernova explosions, double star evolution, and properties of matter under extreme conditions. To date, it…

PSR J1922+37: a 1.9-second pulsar discovered in the direction of the old open cluster NGC 6791

Xiao-Jin Liu, Rahul Sengar, Matthew Bailes +8

More than 300 pulsars have been discovered in Galactic globular clusters; however, none have been found in open clusters. Here we present results from 20-hour pulsar searching obse…

Constraining inflation with nonminimal derivative coupling with the Parkes Pulsar Timing Array third data release

Chang Han, Li-Yang Chen, Zu-Cheng Chen +13

We study an inflation model with nonminimal derivative coupling that features a coupling between the derivative of the inflaton field and the Einstein tensor. This model naturally…
