CDM theory describes the growth of structure through the merger of small halos formed in large numbers early-on, and while these small halos serve as the building blocks of galaxies and clusters, many low mass objects are nonetheless expected to survive to the present epoch. In this seminar, we will explore our current understanding of dwarf galaxies, their impact on hierarchical structure development and the clues about galaxy formation and evolution they carry with them especially as viewed using today's long wavelength forefront instruments Spitzer, ALFA and the VLA and, in the future, ALMA, CCAT and SKA. Wednesdays 2:30-4:25pm EDT (in Ithaca)                      2:30-4:25pm AST (in Arecibo) 2 credits Each week, a team of participants, led by a faculty organizer, will make presentations on selected, coordinated topics. Suggestions and especially volunteers are welcome! |
