Gas flow in barred potentials - III. Effects of varying the Quadrupole
Mattia C. Sormani, James Binney, John Magorrian
We run hydrodynamical simulations of a 2D isothermal non self-gravitating inviscid gas flowing in a rigidly rotating externally imposed potential formed by only two components: a m…
Gas flow in barred potentials II. Bar Driven Spiral Arms
Mattia C. Sormani, James Binney, John Magorrian
Spiral arms that emerge from the ends of a galactic bar are important in interpreting observations of our and external galaxies. It is therefore important to understand the physica…
Gas flow in barred potentials
Mattia C. Sormani, James Binney, John Magorrian
We use a Cartesian grid to simulate the flow of gas in a barred Galactic potential and investigate the effects of varying the sound speed in the gas and the resolution of the grid.…
Counterintuitive effect of gravity on the heat capacity of a metal sphere: re-examination of a well-known problem
Giacomo De Palma, Mattia C. Sormani
A well-known high-school problem asking the final temperature of two spheres that are given the same amount of heat, one lying on a table and the other hanging from a thread, is re…
