The ubiquity of variable radio emission and spin-down rates in pulsars

M. E. Lower, A. Karastergiou, S. Johnston +8

Pulsars are often lauded for their (relative) rotational and radio emission stability over long time scales. However, long-term observing programmes are identifying an increasing n…

The International Pulsar Timing Array second data release: Search for an isotropic Gravitational Wave Background

J. Antoniadis, Z. Arzoumanian, S. Babak +123

We searched for an isotropic stochastic gravitational wave background in the second data release of the International Pulsar Timing Array, a global collaboration synthesizing decad…

Timing of young radio pulsars II. Braking indices and their interpretation

A. Parthasarathy, S. Johnston, R. M. Shannon +8

In Paper I of this series, we detected a significant value of the braking index () for 19 young, high- radio pulsars using 10 years of timing observations from t…

Timing of young radio pulsars I: Timing noise, periodic modulation and proper motion

A. Parthasarathy, R. M. Shannon, S. Johnston +9

The smooth spin-down of young pulsars is perturbed by two non-deterministic phenomenon, glitches and timing noise. Although the timing noise provides insights into nuclear and plas…

Discovery of a Pulsar-powered Bow Shock Nebula in the Small Magellanic Cloud Supernova Remnant DEMS5

Rami Z. E. Alsaberi, C. Maitra, M. D. Filipovi'c +32

We report the discovery of a new Small Magellanic Cloud Pulsar Wind Nebula (PWN) at the edge of the Supernova Remnant (SNR)-DEM S5. The pulsar powered object has a cometary morphol…

Search for a Radio Pulsar in the Remnant of Supernova 1987A

S. -B. Zhang, S. Dai, G. Hobbs +5

We have observed the remnant of supernova SN~1987A (SNR~1987A), located in the Large Magellanic Cloud (LMC), to search for periodic and/or transient radio emission with the Parkes…
