BICEP/Keck Experiments

Colloquium: Astronomy Colloquia | September 11 | 4:10 p.m. | 2 LeConte Hall

Chao-Lin Kuo, Stanford

Department of Astronomy

South Pole-based BICEP/Keck program is a series of experiments focusing on making deep measurements of degree-scale B-mode polarization in the cosmic microwave background. This feature is a unique probe of inflationary gravitational waves (tensor modes) and fundamental physics at energy scales inaccessible to terrestrial particle colliders. This spring, BICEP2 reported a significant detection of...   More >

Dwarf Galaxies: The Nexus of Dark Matter and Chemical Evolution

Colloquium: Astronomy Colloquia | September 18 | 4:10 p.m. | 2 LeConte Hall

Evan Kirby, Caltech

Department of Astronomy

The Local Group's dwarf galaxies are near enough for exquisitely detailed, resolved stellar spectroscopy and diverse enough to conduct experiments on dark matter and chemical evolution. I have collected medium-resolution spectra for thousands of stars in many dwarf galaxies in the Local Group. Innovative techniques applied to these spectra recover velocities precise to a few km/s and detailed...   More >
