Impact of UV Radiation from Giant Spirals on the Evolution of Dwarf Galaxies
S. Mashchenko, C. Carignan, A. Bouchard
We show that ultraviolet radiation, with wavelengths shorter than 2000 A, escaping from the disks of giant spirals could be one of the principal factors affecting the evolution of…

The Impact of External Tidal Fields on the ISM of Dwarf Spheroidals
Sergey Mashchenko, Claude Carignan
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 tida…
