An Equilibrium Model of the Galaxy Determined by Element Abundance Gradients

open access: yesThe Astrophysical Journal
We present a method to determine the gravitational potential of the Milky Way from measurements of the locations, velocities, and element abundances of stars in the Galactic disk.

Reanalysis of the MACHO Constraints on PBH in the Light of Gaia DR3 Data

open access: yesUniverse
The recent astrometric data of hundreds of millions of stars from Gaia DR3 has allowed for a precise determination of the Milky Way rotation curve up to 28 kpc. The data suggest a rapid decline in the density of dark matter beyond 19 kpc.

Statistical Strong Lensing as a Test of Conformal Gravity

open access: yesUniverse
As an alternative gravitational theory to General Relativity (GR), Conformal Gravity (CG) can be verified through astronomical observations. Currently, Mannheim and Kazanas have provided vacuum solutions for cosmological and local gravitational systems ...
