On the triple nature of the PSR J0435+3233 system
Paulo C. C. Freire, Colin J. Clark, Cees G. Bassa +4
The paper presents evidence that the millisecond pulsar PSR J0435+3233 is part of a hierarchical triple system, with a wide-orbit tertiary star causing apparent variations in its s…
Pulsar Discoveries from the TRAPUM UHF Survey of Fermi-LAT Sources
Tinn Thongmeearkom, Colin J. Clark, Rene P. Breton +25
The Fermi Large Area Telescope (LAT) provides advantages for radio pulsar searches by enabling efficient target selection. We can confidently point radio telescopes to the position…
An updated constraint for the Gravitational Wave Background from the Gamma-ray Pulsar Timing Array
Serena Valtolina, Colin J. Clark, Rutger van Haasteren +5
Fermi LAT observations of gamma-ray pulsars can be used to build a pulsar timing array (PTA) experiment to search for gravitational wave (GW) signals at nanohertz frequencies. At t…
Timing Gamma-ray Pulsars using Gibbs Sampling
Colin J. Clark, Serena Valtolina, Lars Nieder +1
Timing analyses of gamma-ray pulsars in the Fermi Large Area Telescope data set can provide sensitive probes of many astrophysical processes, including timing noise in young pulsar…
Einstein@Home Searches for Gamma-ray Pulsars in the Inner Galaxy
C. J. Clark, M. Di Mauro, J. Wu +14
The Fermi Large Area Telescope (LAT) has revealed a mysterious extended excess of GeV gamma-ray emission around the Galactic Center, which can potentially be explained by unresolve…
Multiwavelength observations of a new black-widow millisecond pulsar PSR J1544-2555
Sergio Belmonte Diaz, Tinn Thongmeearkom, Adipol Phosrisom +20
We report the discovery of a new black-widow millisecond pulsar, PSR J1544-2555, associated with the Fermi-LAT source 4FGL J1544.2-2554. Optical, radio, and gamma-ray observations…
