NICER X-ray Observations of Seven Nearby Rotation-Powered Millisecond Pulsars

S. Guillot, M. Kerr, P. S. Ray +18

NICER observed several rotation-powered millisecond pulsars to search for or confirm the presence of X-ray pulsations. When broad and sine-like, these pulsations may indicate therm…

The LOFAR Tied-Array All-Sky Survey (LOTAAS): Characterization of 20 pulsar discoveries and their single-pulse behavior

D. Michilli, C. Bassa, S. Cooper +11

We are using the LOw-Frequency ARray (LOFAR) to perform the LOFAR Tied-Array All-Sky (LOTAAS) survey for pulsars and fast transients. Here we present the astrometric and rotational…

Radio emission from a pulsar's magnetic pole revealed by general relativity

Gregory Desvignes, Michael Kramer, Kejia Lee +7

Binary pulsars are affected by general relativity (GR), causing the spin axes of each pulsar to precess. We present polarimetric radio observations of PSR J1906+0746 that demonstra…

A LOFAR census of non-recycled pulsars: extending below 80 MHz

A. V. Bilous, L. Bondonneau, V. I. Kondratiev +9

We present the results from the low-frequency (40--78 MHz) extension of the first LOFAR pulsar census of non-recycled pulsars. We have used the Low-Band Antennas of the LOFAR core…

Timing of PSR J2055+3829, an eclipsing black widow pulsar discovered with the Nançay Radio Telescope

L. Guillemot, F. Octau, I. Cognard +5

We report on the timing observations of the millisecond pulsar PSR J2055+3829 originally discovered as part of the SPAN512 survey conducted with the Nançay Radio Telescope. The pul…

Thermal X-ray emission identified from the millisecond pulsar PSR J1909-3744

N. A. Webb, D. Leahy, S. Guillot +5

Pulsating thermal X-ray emission from millisecond pulsars can be used to obtain constraints on the neutron star equation of state, but to date only five such sources have been iden…

The LOFAR Tied-Array All-Sky Survey (LOTAAS): Survey overview and initial pulsar discoveries

S. Sanidas, S. Cooper, C. G. Bassa +20

We present an overview of the LOFAR Tied-Array All-Sky Survey (LOTAAS) for radio pulsars and fast transients. The survey uses the high-band antennas of the LOFAR Superterp, the den…

On the usefulness of existing Solar-wind models for pulsar timing corrections

C. Tiburzi, J. P. W. Verbiest, G. M. Shaifullah +15

Dispersive delays due to the Solar wind introduce excess noise in high-precision pulsar timing experiments, and must be removed in order to achieve the accuracy needed to detect, e…
