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

Andrés F. Vargas, Andrew Melatos, Julian B. Carlin +3

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

Hierarchical Bayesian estimation of population-level torque law parameters from anomalous pulsar braking indices

Andrés F. Vargas, Julian B. Carlin, Andrew Melatos

Abridged. Stochastic fluctuations in the spin frequency $ν$ of a rotation-powered pulsar affect how accurately one measures the power-law braking index, $n_{pl}$ , defined throu…

State-space algorithm for detecting the nanohertz gravitational wave background

Tom Kimpson, Andrew Melatos, Joseph O'Leary +11

The stochastic gravitational wave background (SGWB) can be observed in the nanohertz band using a pulsar timing array (PTA). Here a computationally efficient state-space framework…
