Star Formation in a Galactic Context

Colloquium: Astronomy Colloquia | November 6 | 4:10 p.m. | 2 LeConte Hall

Adam Leroy, NRAO

Department of Astronomy

Star formation in galaxies is a result of a balance of processes at a range of scales: the formation of bound, cold clouds form a diffuse atomic medium, the condensation of dense, star-forming structures within these clouds, and the birth of stars in this dense gas. I will discuss some of what we learn about these processes based on multi-wavelength, resolved studies of nearby galaxies,...   More >

The Dark Ages Radio Explorer (DARE)

Colloquium: Astronomy Colloquia | November 13 | 4:10 p.m. | 2 LeConte Hall

Jack Burns, University of Colorado

Department of Astronomy

In the New Worlds, New Horizons in Astronomy & Astrophysics Decadal Survey, Cosmic Dawn was singled out as one of the top astrophysics priorities for this decade. Specifically, the Decadal report asked "when and how did the first galaxies form out of cold clumps of hydrogen gas and start to shine—when was our cosmic dawn?" It proposed "astronomers must now search the sky for these infant galaxies...   More >

Science Highlights from the Nuclear Spectroscopic Telescope Array (NuSTAR): Bringing the High Energy Universe into Focus

Colloquium: Astronomy Colloquia | November 20 | 4:10 p.m. | 2 LeConte Hall

Fiona Harrison, Caltech

Department of Astronomy

The Nuclear Spectroscopic Telescope Array, the first focusing high-energy X-ray (3 - 79 keV) telescope in orbit, extends sensitive X-ray observations above the band pass where Chandra and XMM-Newton operate. With an unprecedented combination of sensitivity, spectral and imaging resolution above 10 keV, NuSTAR is advancing our understanding of black holes, neutron stars, and supernova remnants.
