The Ecology of the Central Molecular Zone (CMZ):

The Nearest Galactic Nucleus

Recent surveys are revolutionizing our understanding of the central regions of our Galaxy.   In addition to the nearest super-massive black-hole, the Central Molecular Zone (CMZ) contains the most massive, densest, and most turbulent molecular clouds in the Milky Way, as well as some of the most active sites of star and star cluster formation.  Yet, the rate of star formation per unit mass of dense gas is lower than in disk molecular clouds, or in extra-galactic disks. To account for these results, the Schmidt-Kennicutt relations, which prescribes the surface density of star formation to the surface density of dense gas in galactic disks, may have a second parameter such as the cloud internal velocity dispersion.    I will present a broad review of the ecology of star formation and the interstellar medium in the CMZ, and present recent results from The Bolocam Galactic Plane Survey (BGPS), Herschel Galactic Plane Survey (Hi-GAL), and Spitzer.

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
