It was a beautiful day for #flying in southern California. Visibility was at least 90 miles, and I managed to squeeze nearly 2 hours out of a few thermals near Warner Springs before making a stop at Santa Catalina Island on the way home.

Is Milky Way stable all the way ? A TNG50 view from cosmic noon to the present day
We investigate the stability of Milky Way analogs (MWAs) in the \texttt{TNG50} simulation against the growth of local axisymmetric instabilities, tracing their evolution from cosmic noon ($z=2.5$) to the present day ($z=0$). Using a two-component stability criterion that accounts for stars, gas, and the force field of the dark matter halo, we compute the net stability parameter ($Q_{T}$), the critical gas surface density ($Σ_{c}$), and the instability timescale ($τ$) for 10 barred and 10 unba…
