Periodicity makes galactic shocks unstable - I. Linear analysis
Mattia C. Sormani, Emanuele Sobacchi, Steven N. Shore +2
We study the dynamical stability of stationary galactic spiral shocks. The steady-state equilibrium flow contains a shock of the type derived by Roberts in the tightly wound approx…
A theoretical explanation for the Central Molecular Zone asymmetry
Mattia C. Sormani, Robin G. Tress, Matthew Ridley +5
It has been known for more than thirty years that the distribution of molecular gas in the innermost 300 parsecs of the Milky Way, the Central Molecular Zone, is strongly asymmetri…
Nuclear Spirals in the inner Milky Way
Matthew Ridley, Mattia C. Sormani, Robin G. Treß +2
We use hydrodynamical simulations to construct a new coherent picture for the gas flow in the Central Molecular Zone (CMZ), the region of our Galaxy within $R\leq 500\, \mathrm{pc}…
