Thorsten Naab . MPA, . Garching. . What regulates galaxy formation? . Leiden, April, 22. nd. How do massive galaxies get their gas and stars?. Gas accretion involves dissipation – energy can be radiated away . D.J. Pisano. (West Virginia University). Why study galaxy environment?. Nature vs. Nurture. Can they be distinguished?. What does the environment do to a galaxy?. What would a galaxy look like without any environmental influence?. With a wide-field multi-IFU spectrograph. Cluster studies. Clusters provide large samples of galaxies in a moderate field. Unique perspective on the interaction of galaxies with their environment. As they operate much as a closed box, they are useful as tracers of galaxy evolution and of cosmology. Exercise . 20.16.

IMPEACHMENT IS THE PROCESS OF ATTEMPTING TO WEAKEN THE PERCEIVED CREDIBILITY OF A WITNESS. MOST COMMONLY DONE ON CROSS. AT LEAST SIX METHODS OF IMPEACHMENT, EACH WITH ITS OWN RULES LIMITING REACH.
