Accelerating pulsar timing data analysis

Rutger van Haasteren

The analysis of pulsar timing data, especially in pulsar timing array (PTA) projects, has encountered practical difficulties: evaluating the likelihood and/or correlation-based sta…

Hyper-efficient model-independent Bayesian method for the analysis of pulsar timing data

Lindley Lentati, Paul Alexander, Michael P. Hobson +4

A new model independent method is presented for the analysis of pulsar timing data and the estimation of the spectral properties of an isotropic gravitational wave background (GWB)…

THC: a new high-order finite-difference high-resolution shock-capturing code for special-relativistic hydrodynamics

David Radice, Luciano Rezzolla

We present THC: a new high-order flux-vector-splitting code for Newtonian and special-relativistic hydrodynamics designed for direct numerical simulations of turbulent flows. Our c…

Multi-color Cavity Metrology

Kiwamu Izumi, Koji Arai, Bryan Barr +11

Long baseline laser interferometers used for gravitational wave detection have proven to be very complicated to control. In order to have sufficient sensitivity to astrophysical gr…

Subtraction of test mass angular noise in the LISA Technology Package interferometer

Felipe Guzmán Cervantes, Frank Steier, Gudrun Wanner +2

We present recent sensitivity measurements of the LISA Technology Package interferometer with articulated mirrors as test masses, actuated by piezo-electric transducers. The requir…

Understanding and analysing time-correlated stochastic signals in pulsar timing

Rutger van Haasteren, Yuri Levin

Although it is widely understood that pulsar timing observations generally contain time-correlated stochastic signals (TCSSs; red timing noise is of this type), most data analysis…
