# $\texttt{galkin}$: a new compilation of the Milky Way rotation curve data

## TL;DR

galkin is a comprehensive, user-friendly compilation of Milky Way rotation curve data from various sources, designed to aid dynamical studies and dark matter research.

## Contribution

It provides a new, curated dataset of 2780 kinematic measurements and a tool for easy data handling, covering 3 to 20 kpc in the Galaxy.

## Key findings

- Enables detailed dynamical analysis of the Milky Way
- Facilitates constraints on dark matter distribution
- Supports tests of modified gravity theories

## Abstract

We present $\texttt{galkin}$, a novel compilation of kinematic measurements tracing the rotation curve of our Galaxy, together with a tool to treat the data. The compilation is optimised to Galactocentric radii between 3 and 20 kpc and includes the kinematics of gas, stars and masers in a total of 2780 measurements carefully collected from almost four decades of literature. A simple, user-friendly tool is provided to select, treat and retrieve the data of all source references considered. This tool is especially designed to facilitate the use of kinematic data in dynamical studies of the Milky Way with various applications ranging from dark matter constraints to tests of modified gravity.
