# Summary | ||
|
||
The forces on stars, galaxies, and dark matter under external gravitational | ||
fields lead to the dynamical evolution of structures in the universe. The orbits | ||
of these bodies are therefore key to understanding the formation, history, and | ||
future state of galaxies. The field of "galactic dynamics," which aims to model | ||
the gravitating components of galaxies to study their structure and evolution, | ||
is now well-established, commonly taught, and frequently used in astronomy. | ||
Aside from toy problems and demonstrations, the majority of problems require | ||
efficient numerical tools, many of which require the same base code (e.g., for | ||
performing numerical orbit integration). | ||
|
||
# Statement of need | ||
|
||
`Gala` is an Astropy-affiliated Python package for galactic dynamics. Python | ||
enables wrapping low-level languages (e.g., C) for speed without losing | ||
flexibility or ease-of-use in the user-interface. The API for `Gala` was | ||
designed to provide a class-based and user-friendly interface to fast (C or | ||
Cython-optimized) implementations of common operations such as gravitational | ||
potential and force evaluation, orbit integration, dynamical transformations, | ||
and chaos indicators for nonlinear dynamics. `Gala` also relies heavily on and | ||
interfaces well with the implementations of physical units and astronomical | ||
coordinate systems in the `Astropy` package [@astropy] (`astropy.units` and | ||
`astropy.coordinates`). | ||
|
||
`Gala` was designed to be used by both astronomical researchers and by | ||
students in courses on gravitational dynamics or astronomy. It has already been | ||
used in a number of scientific publications [@Pearson:2017] and has also been | ||
used in graduate courses on Galactic dynamics to, e.g., provide interactive | ||
visualizations of textbook material [@Binney:2008]. The combination of speed, | ||
design, and support for Astropy functionality in `Gala` will enable exciting | ||
scientific explorations of forthcoming data releases from the *Gaia* mission | ||
[@gaia] by students and experts alike. | ||
|
||
# Mathematics | ||
|
||
Single dollars ($) are required for inline mathematics e.g. $f(x) = e^{\pi/x}$ | ||
|
||
Double dollars make self-standing equations: | ||
|
||
$$\Theta(x) = \left\{\begin{array}{l} | ||
0\textrm{ if } x < 0\cr | ||
1\textrm{ else} | ||
\end{array}\right.$$ | ||
|
||
You can also use plain \LaTeX for equations | ||
\begin{equation}\label{eq:fourier} | ||
\hat f(\omega) = \int_{-\infty}^{\infty} f(x) e^{i\omega x} dx | ||
\end{equation} | ||
and refer to \autoref{eq:fourier} from text. | ||
|
||
# Citations | ||
|
||
Citations to entries in paper.bib should be in | ||
[rMarkdown](http://rmarkdown.rstudio.com/authoring_bibliographies_and_citations.html) | ||
format. | ||
|
||
If you want to cite a software repository URL (e.g. something on GitHub without a preferred | ||
citation) then you can do it with the example BibTeX entry below for @fidgit. | ||
|
||
For a quick reference, the following citation commands can be used: | ||
- `@author:2001` -> "Author et al. (2001)" | ||
- `[@author:2001]` -> "(Author et al., 2001)" | ||
- `[@author1:2001; @author2:2001]` -> "(Author1 et al., 2001; Author2 et al., 2002)" | ||
|
||
# Figures | ||
|
||
Figures can be included like this: | ||
![Caption for example figure.\label{fig:example}](figure.png) | ||
and referenced from text using \autoref{fig:example}. | ||
|
||
Figure sizes can be customized by adding an optional second parameter: | ||
![Caption for example figure.](figure.png){ width=20% } | ||
