Hierarchical Bayesian estimation of population-level torque law parameters from $68$ young radio pulsars observed with the Murriyang telescope

AndrÃ©s F. Vargas, Andrew Melatos, Julian B. Carlin +3

Abridged. The measured braking index, $n = I^½ I^¨ ½/ I^˙ ½^{2}$ , of a rotation-powered pulsar with spin frequency $I^½$ and braking torque $K I^½^{n_{pl}}$ , features secular and sto…

Tiny-Scale Properties within the Interstellar Medium towards PSR J1644 $-$ 4559: I. Observational Evidence of Turbulence-induced Tiny Scale Atomic Structures

Mengting Liu, Di Li, J. R. Dawson +21

We investigated HI absorption toward a single pulsar, PSR J1644 $-$ 4559, and its variability over timescales from days to years, using Murriyang, CSIRO's Parkes Radio Telescope. Our…
