EXP: a Python/C++ package for basis function expansion methods in galactic dynamics
Michael S. Petersen, Martin D. Weinberg
We present the public release of EXP, a basis function expansion C++ library and Python package for running N-body galactic simulations and dynamical discovery. EXP grew out of the…
lintsampler: Easy random sampling via linear interpolation
Aneesh P. Naik, Michael S. Petersen
'lintsampler' provides a Python implementation of a technique we term 'linear interpolant sampling': an algorithm to efficiently draw pseudo-random samples from an arbitrary probab…
Predicting the linear response of self-gravitating stellar spheres and discs with LinearResponse.jl
Michael S. Petersen, Mathieu Roule, Jean-Baptiste Fouvry +2
We present LinearResponse.jl, an efficient, versatile public library written in julia to compute the linear response of self-gravitating (3D spherically symmetric) stellar spheres…
RomAndromeda: The Roman Survey of the Andromeda Halo
Arjun Dey, Joan Najita, Carrie Filion +50
As our nearest large neighbor, the Andromeda Galaxy provides a unique laboratory for investigating galaxy formation and the distribution and substructure properties of dark matter…
Measuring the dynamical length of galactic bars
Michael S. Petersen, Martin D. Weinberg, Neal Katz
We define a physically-motivated measure for galactic bar length, called the dynamical length. The dynamical length of the bar corresponds to the radial extent of the orbits that a…
Correlating Changes in Spot Filling Factors with Stellar Rotation: The Case of LkCa 4
Facundo Pérez Paolino, Jeffrey S. Bary, Michael S. Petersen +4
We present a multi-epoch spectroscopic study of LkCa 4, a heavily spotted non-accreting T Tauri star. Using SpeX at NASA's Infrared Telescope Facility (IRTF), 12 spectra were colle…
