A detailed study of giant pulses from PSR B1937+21 using the Large European Array for Pulsars (2018)
Journal Article
McKee, J. W., Stappers, B. W., Bassa, C. G., Chen, S., Cognard, I., Gaikwad, M., …Zhu, W. W. (2019). A detailed study of giant pulses from PSR B1937+21 using the Large European Array for Pulsars. Monthly notices of the Royal Astronomical Society, 483(4), 4784-4802. https://doi.org/10.1093/mnras/sty3058

We have studied 4265 giant pulses (GPs) from the millisecond pulsar B1937+21; the largest-ever sample gathered for this pulsar, in observations made with the Large European Array for Pulsars. The pulse energy distribution of GPs associated with the i... Read More about A detailed study of giant pulses from PSR B1937+21 using the Large European Array for Pulsars.

Tests of gravitational symmetries with pulsar binary J1713+0747 (2018)
Journal Article
Zhu, W. W., Desvignes, G., Wex, N., Caballero, R. N., Champion, D. J., Demorest, P. B., …Tiburzi, C. (2019). Tests of gravitational symmetries with pulsar binary J1713+0747. Monthly notices of the Royal Astronomical Society, 482(3), 3249-3260. https://doi.org/10.1093/mnras/sty2905

Symmetries play a fundamental role in modern theories of gravity. The strong equivalence principle (SEP) constitutes a collection of gravitational symmetries which are all implemented by general relativity. Alternative theories, however, are generall...

Studying the Solar system with the International Pulsar Timing Array (2018)
Journal Article
Caballero, R. N., Guo, Y. J., Lee, K. J., Lazarus, P., Champion, D. J., Desvignes, G., …Zhu, W. W. (2018). Studying the Solar system with the International Pulsar Timing Array. Monthly notices of the Royal Astronomical Society, 481(4), 5501-5516. https://doi.org/10.1093/MNRAS/STY2632

Pulsar-timing analyses are sensitive to errors in the Solar-system ephemerides (SSEs) that timing models utilize to estimate the location of the Solar-system barycentre, the quasi-inertial reference frame to which all recorded pulse times-of-arrival...

Improving timing sensitivity in the microhertz frequency regime: limits from PSR J1713+0747 on gravitational waves produced by supermassive black hole binaries (2018)
Journal Article
Perera, B. B., Stappers, B. W., Babak, S., Keith, M. J., Antoniadis, J., Bassa, C. G., …Taylor, S. R. (2018). Improving timing sensitivity in the microhertz frequency regime: limits from PSR J1713+0747 on gravitational waves produced by supermassive black hole binaries. Monthly notices of the Royal Astronomical Society, 478(1), 218-227. https://doi.org/10.1093/mnras/sty1116

We search for continuous gravitational waves (CGWs) produced by individual supermassive black hole binaries in circular orbits using high-cadence timing observations of PSR J1713+0747. We observe this millisecond pulsar using the telescopes in the Eu...

Temporal variations in scattering and dispersion measure in the Crab Pulsar and their effect on timing precision (2018)
Journal Article
McKee, J. W., Lyne, A. G., Stappers, B. W., Bassa, C. G., & Jordan, C. A. (2018). Temporal variations in scattering and dispersion measure in the Crab Pulsar and their effect on timing precision. Monthly notices of the Royal Astronomical Society, 479(3), 4216-4224. https://doi.org/10.1093/mnras/sty1727

We have measured variations in scattering time-scales in the Crab Pulsar over a 30-yr period, using observations made at 610 MHz with the 42-ft telescope at Jodrell Bank Observatory. Over more recent years, where regular Lovell Telescope observations... Read More about Temporal variations in scattering and dispersion measure in the Crab Pulsar and their effect on timing precision.
