The Intricate Role of Cold Gas and Dust in Galaxy Evolution at Early Cosmic Epochs

Abstract

Over the past decade, great progress has been made in studies of the atomic and molecular interstellar medium and dust-obscured star formation in high redshift galaxies, resulting in a vastly improved picture of the physical properties and chemical composition of the gas and dust in galaxies in the early universe. With the recent completionof the Karl G. Jansky Very Large Array (VLA) and the Atacama Large (sub)Millimeter Array (ALMA), it has now become possible to advance these studies to the next level through sensitive, broad-band molecular line spectroscopy, spatially-resolved imaging of the gas and dust, and deep field surveys of considerable cosmic volumes in both line and continuum emission back to the earliest cosmic epochs. I will present a suite of new scientific investigations that exemplify the range of the exciting new research enabled by the VLA and ALMA as we are approaching the 2020s.

 

 

 

 

Connect with NRAO

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.
