| Abstract: |
It was found that for three dwarf spheroidal galaxies -- Sculptor, Tucana, and Cetus - -there is a correspondence between the distribution of associated HI gas and the projected tidal axis direction. Numerical hydrodynamical simulations confirmed the following scenario: supernova Ia explosions remove most of the interstellar medium beyond the tidal radius of the dwarf galaxy, with most of the mass being in clouds moving along the principal tidal axis. |
