A NICER View of PSR J0030+0451: Millisecond Pulsar Parameter Estimation [PDF]

open access: yesAstrophysical Journal, 2019
We report on Bayesian parameter estimation of the mass and equatorial radius of the millisecond pulsar PSR J0030+0451, conditional on pulse-profile modeling of Neutron Star Interior Composition Explorer X-ray spectral-timing event data.

GW190814's Secondary Component with Mass 2.50–2.67 M⊙ as a Superfast Pulsar [PDF]

open access: yesAstrophysical Journal, 2020
We use Stergioulas’s RNS code for investigating fast pulsars with equations of state (EOSs) on the causality surface (where the speed of sound is equal to that of light) of the high-density EOS parameter space satisfying all known constraints from both ...

Spatial Modulation Search Applied to the Search and Confirmation of Highly Scintillated Pulsars at FAST with A Pulsar Discovered in M3 [PDF]

open access: yes, 2021
We present a pulsar candidate identification and confirmation procedure based on a position-switch mode during the pulsar search observations. This method enables the simultaneous search and confirmation of a pulsar in a single observation, by utilizing the different spatial features of a pulsar signal and a radio frequency interference (RFI). Based on

Radio Pulsars [PDF]

open access: yesSpace Science Reviews, 2015
Almost 50 years after radio pulsars were discovered in 1967, our understanding of these objects remains incomplete. On the one hand, within a few years it became clear that neutron star rotation gives rise to the extremely stable sequence of radio pulses, that the kinetic energy of rotation provides the reservoir of energy, and that electromagnetic ...

The Australia Telescope National Facility Pulsar Catalogue [PDF]

open access: yes, 2003
We have compiled a new and complete catalog of the main properties of the 1509 pulsars for which published information currently exists. The catalog includes all spin-powered pulsars, as well as anomalous X-ray pulsars and soft gamma-ray repeaters ...
