Terraforming the Milky Way galaxy (Extended)

, 2023
The concept of terraforming the entire Milky Way galaxy within a timeframe of 400,000 to 1 million years, as proposed by NAR (Ndoni Advanced Robotics), presents several theoretical and speculative challenges, spanning immense timeframes and involving technologies far beyond our current understanding.

Observational Constraints of Radial Migration in the Galactic Disk Driven by the Slowing Bar

The Astrophysical Journal Letters
Radial migration is an important dynamical effect that has reshaped the Galactic disk, but its origin has yet to be elucidated. In this work, we present evidence that resonant dragging by the corotation of a decelerating bar could be the main driver of ...

The satellite galaxies of the Milky Way and Andromeda

The satellite galaxies of the Local Group provide us with an important probe of galaxy formation, evolution, and cosmology. The two large spirals that dominate this group -- the Milky Way and Andromeda -- are each host to tens of satellites, ranging in stellar mass from $M_*=3\times10^9\,{\rm M_\odot}$ down to as little as $M_*\sim1000\,{\rm M_\odot}$.
