Rotational and radio emission properties of PSR J0738-4042 over half a century

M. E. Lower, S. Johnston, A. Karastergiou +14

We present a comprehensive study of the rotational and emission properties of PSR J07384042 using a combination of observations taken by the Deep Space Network, Hartebeesthoek,…

The Faraday Rotation Measure Grid of the LOFAR Two-metre Sky Survey: Data Release 2

S. P. O'Sullivan, T. W. Shimwell, M. J. Hardcastle +24

A Faraday rotation measure (RM) catalogue, or RM Grid, is a valuable resource for the study of cosmic magnetism. Using the second data release (DR2) from the LOFAR Two-metre Sky Su…

Pulsar polarization: a broad-band population view with the Parkes Ultra-Wideband receiver

L. S. Oswald, S. Johnston, A. Karastergiou +7

The radio polarization properties of the pulsar population are only superficially captured by the conventional picture of pulsar radio emission. We study the broadband polarization…

Searching for pulsars associated with polarised point sources using LOFAR: Initial discoveries from the TULIPP project

C. Sobey, C. G. Bassa, S. P. O'Sullivan +15

Discovering radio pulsars, particularly millisecond pulsars (MSPs), is important for a range of astrophysical applications, such as testing theories of gravity or probing the magne…

The impact of glitches on young pulsar rotational evolution

Marcus E. Lower, Simon Johnston, Liam Dunn +10

We report on a timing programme of 74 young pulsars that have been observed by the Parkes 64-m radio telescope over the past decade. Using modern Bayesian timing techniques, we hav…

A broadband radio study of PSR J0250+5854: the slowest-spinning radio pulsar known

C. H. Agar, P. Weltevrede, L. Bondonneau +19

We present radio observations of the most slowly rotating known radio pulsar PSR J0250+5854. With a 23.5 s period, it is close, or even beyond, the - diagram region tho…
