Inhomogeneous Galactic chemical evolution: modelling ultra-faint dwarf galaxies of the Large Magellanic Cloud (2023)
Journal Article
Alexander, R. K., Vincenzo, F., Ji, A. P., Richstein, H., Jordan, C. J., & Gibson, B. K. (2023). Inhomogeneous Galactic chemical evolution: modelling ultra-faint dwarf galaxies of the Large Magellanic Cloud. Monthly notices of the Royal Astronomical Society, 522(4), 5415-5433. https://doi.org/10.1093/mnras/stad1312

Ultra-faint dwarf galaxies (UFDs) are among the oldest and most metal-poor galaxies in the cosmos, observed to contain no gas and a high dark matter mass fraction. Understanding the chemical abundance dispersion in such extreme environments could she...

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...

21 year timing of the black-widow pulsar J2051-0827 (2016)
Journal Article
Shaifullah, G., Verbiest, J. P., Freire, P. C., Tauris, T. M., Wex, N., Oslowski, S., …Tiburzi, C. (2016). 21 year timing of the black-widow pulsar J2051-0827. Monthly notices of the Royal Astronomical Society, 462(1), 1029-1038. https://doi.org/10.1093/mnras/stw1737

Timing results for the black-widow pulsar J2051-0827 are presented, using a 21 year data set from four European Pulsar Timing Array telescopes and the Parkes radio telescope. This data set, which is the longest published to date for a black-widow sys... Read More about 21 year timing of the black-widow pulsar J2051-0827.

A millisecond pulsar in an extremely wide binary system (2016)
Journal Article
Bassa, C. G., Janssen, G. H., Stappers, B. W., Tauris, T. M., Wevers, T., Jonker, P. G., …Zhu, W. W. (2016). A millisecond pulsar in an extremely wide binary system. Monthly notices of the Royal Astronomical Society, 460(2), 2207-2222. https://doi.org/10.1093/mnras/stw1134

We report on 22 yr of radio timing observations of the millisecond pulsar J1024-0719 by the telescopes participating in the European Pulsar Timing Array (EPTA). These observations reveal a significant second derivative of the pulsar spin frequency an... Read More about A millisecond pulsar in an extremely wide binary system.

High-precision timing of 42 millisecond pulsars with the European Pulsar Timing Array (2016)
Journal Article

Carbon-rich presolar grains from massive stars : subsolar ¹²C/¹³C and ¹⁴N/¹⁵N ratios and the mystery of ¹⁵N (2015)
Journal Article
Pignatari, M., Zinner, E., Hoppe, P., J. Jordan, C., K. Gibson, B., Trappitsch, R., …X. Timmes, F. (2015). Carbon-rich presolar grains from massive stars : subsolar ¹²C/¹³C and ¹⁴N/¹⁵N ratios and the mystery of ¹⁵N. Astrophysical journal. Letters, 808(2), L43. https://doi.org/10.1088/2041-8205/808/2/L43

Carbon-rich grains with isotopic anomalies compared to the Sun are found in primitive meteorites. They were made by stars, and carry the original stellar nucleosynthesis signature. Silicon carbide grains of Type X and C and low-density (LD) graphites... Read More about Carbon-rich presolar grains from massive stars : subsolar ¹²C/¹³C and ¹⁴N/¹⁵N ratios and the mystery of ¹⁵N.
