One of the major goals of the field of Milky Way dynamics is to recover the gravitational potential field. Mapping the potential would allow us to determine the spatial distribution of matter - both baryonic and dark - throughout the Galaxy. We present a novel method for determining the gravitational field from a snapshot of the phase-space positions of stars, based only on minimal physical assumptions. We first train a normalizing flow on a sample of observed phase-space positions, obtaining a… Expand

TLDR
This work proposes to apply the precision radial velocity method, optimized in recent years for exoplanet astronomy, to measure the change in the velocity of stars over time, thereby providing a direct probe of the local gravitational potential in the Galaxy. Expand
Mapping the galactic gravitational potential with peculiar acceleration
It has been suggested recently that the change in cosmological redshift (the Sandage test of expansion) could be observed in the next generation of large telescopes and ultra-stable spectrographs. InExpand
Analysing surveys of our Galaxy – II. Determining the potential
We consider the problem of determining the Galaxy's gravitational potential from a star catalogue. We show that orbit-based approaches to this problem suffer from unacceptable numerical noiseExpand

Stellar accelerations and the galactic gravitational field
Abstract Typical stars in the Milky Way galaxy have velocities of hundreds of kilometres per second and experience gravitational accelerations of $\sim\!10^{-10}~{\rm m\,s}^{-2}$, resulting inExpand
Dynamics for galactic archaeology
Abstract Our Galaxy is a complex machine in which several processes operate simultaneously: metal-poor gas is accreted, is chemically enriched by dying stars, and then drifts inwards, surrenderingExpand

Constraining the Galaxy's dark halo with RAVE stars
We use the kinematics of ∼200000 giant stars that lie within ∼1.5kpc of the plane to measure the vertical profile of mass density near the Sun. We find that the dark mass contained within theExpand
