A Gamma-ray Pulsar Timing Array Constrains the Nanohertz Gravitational Wave Background
M. Ajello, W. B. Atwood, L. Baldini +129
After large galaxies merge, their central supermassive black holes are expected to form binary systems whose orbital motion generates a gravitational wave background (GWB) at nanoh…
Is the black-widow pulsar PSR J1555-2908 in a hierarchical triple system?
L. Nieder, M. Kerr, C. J. Clark +4
The 559 Hz black-widow pulsar PSR J1555-2908, originally discovered in radio, is also a bright gamma-ray pulsar. Timing its pulsations using 12 yr of Fermi-LAT gamma-ray data revea…
Discovery, Timing, and Multiwavelength Observations of the Black Widow Millisecond Pulsar PSR J1555-2908
Paul S. Ray, Lars Nieder, Colin J. Clark +21
We report the discovery of PSR J1555-2908, a 1.79 ms radio and gamma-ray pulsar in a 5.6 hr binary system with a minimum companion mass of 0.052 . This fast and energetic…
Measuring the mass of the black widow PSR J1555-2908
M. R. Kennedy, R. P. Breton, C. J. Clark +8
Accurate measurements of the masses of neutron stars are necessary to test binary evolution models, and to constrain the neutron star equation of state. In pulsar binaries with no…
Discovery of a Gamma-ray Black Widow Pulsar by GPU-accelerated Einstein@Home
L. Nieder, C. J. Clark, D. Kandel +39
We report the discovery of 1.97 ms period gamma-ray pulsations from the 75 minute orbital-period binary pulsar now named PSR J1653-0158. The associated Fermi Large Area Telescope g…
Radio pulsations from the -ray millisecond pulsar PSR J2039-5617
A. Corongiu, R. P. Mignani, A. S. Seyffert +9
The predicted nature of the candidate redback pulsar 3FGL\,J2039.65618 was recently confirmed by the discovery of -ray millisecond pulsations (Clark et al. 2020, hereafter Pa…
