Determining the Milky Way gravitational potential without selection functions
Taavet Kalda, Gregory Green
Selection effects, such as interstellar extinction and varying survey depth, complicate efforts to determine the gravitational potential - and thus the distribution of baryonic and…

Quadrupole signature as a kinematic diagnostic to constrain bar properties : implications for the Milky Way
Soumavo Ghosh, Taavet Kalda, Paola Di Matteo +4
The presence of a 'butterfly' or a quadrupole structure in the stellar mean radial velocity () field of the Milky Way is well known from the Gaia and the APOGEE surveys. Pas…

Deep Potential: Recovering the gravitational potential and local pattern speed in the solar neighborhood with GDR3 using normalizing flows
Taavet Kalda, Gregory M. Green
The gravitational potential of the Milky Way encodes information about the distribution of all matter -- including dark matter -- throughout the Galaxy. Gaia data release 3 has rev…
