Self-consistent dynamical modelling of the Milky Way bar with orbital frequency analysis
Zachary Langford, Robyn Sanderson, Madeline Lucey +1
We present an update to the frequency analysis method for measuring the properties of a galactic bar. The method involves computing the fundamental frequencies of orbits in rotatin…

Order-by-order Modeling of Exoplanet Radial Velocity Data
Zachary Langford, Cullen Blake, Samuel Halverson +12
Precise radial velocity (RV) measurements are a crucial tool for exoplanet discovery and characterization. Today, the majority of these measurements are derived from Echelle spectr…

A differentiable N-body code for transit timing and dynamical modelling -- II. Photodynamics
Zachary Langford, Eric Agol
Exoplanet transits contain substantial information about the architecture of a system. By fitting transit light curves we can extract dynamical parameters and place constraints on…
