New pipeline estimates galactic potential using symbolic regression

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new pipeline to estimate the distribution function of stars in the galaxy, which is crucial for understanding dark matter density. This method linearizes the collisionless Boltzmann equation and focuses on stellar number counts rather than the equation's residual, addressing discrepancies in previous estimates. The approach allows for direct measurement of the local force field, which is then fitted using symbolic regression, yielding results consistent with the classical self-gravitating isothermal disc model.

    Closed-Form of the Local Galactic Potential and Stellar Distribution Function from Gaia DR3

    arXiv:2609.09011v1 Announce Type: cross Abstract: The local dark matter density determines the strength of the signal expected in direct-detection experiments, yet published estimates from stellar motions disagree by more than their errors, and the most recent machine-learning an…
