Abstract: One of the most fundamental questions in galaxy formation and evolution is to understanding the establishment of the Hubble sequence, particularly how blue, star-forming galaxies are transformed into red, quiescent galaxies. In this talk I will present some new insights into this question based on recent observational results at high redshift, primarily at z > 2, and discuss how star-formation is regulated and quenched in massive galaxies and what are the possible roles of environment and supermassive black holes in this process. Specifically, I will show how ALMA unveils a significant population of promising progenitors of the earliest-quenched galaxies at z~4, and how we captured the onset of environmental effects on massive galaxy evolution in the most distant galaxy clusters at z=2.5.

Abstract: The two Magellan 6.5 meter telescopes were designed, constructed and are currently being operated at Las Campanas Observatory in Chile by a consortium of US universities and research institutions. This talk discusses some of the thinking that went into their design, notable features, and the transport of the telescope to the observatory and installation on site. The talk concludes with the results of some recent investigations of seismic performance.
