Environmental Impact on the Interstellar Medium of Disk Galaxies — •Jan Bolte¹, Elke Roediger², Marcus Brüggen², and Dieter Breitschwerdt¹ — ¹Zentrum für Astronomie und Astrophysik, TU Berlin, Hardenbergstr. 36, 10623 Berlin, Germany — ²Hamburger Sternwarte, Universität Hamburg, Gojenbergsweg 112, 21029 Hamburg, Germany

Hydrodynamical simulations of the intercluster medium provide us with the orbit of a disk galaxy through a galaxy cluster. In a zoom-in simulation we study the impact of the time-dependently changing boundary conditions on the interstellar medium of the disk galaxy. In particular, we discuss the resulting star formation rate and the turbulent structure of the interstellar medium and compare the results with simulations with constant boundary conditions.
