Reverberation mapping as a probe of black hole masses and AGN structure: new results from intensive monitoring campaigns

Colloquium: Astronomy Colloquia | October 1 | 4 p.m. | 1 LeConte Hall

Aaron Barth, UC Irvine

Department of Astronomy

The method of reverberation mapping uses the time delay between continuum and emission-line variations in active galactic nuclei to probe the structure of the broad-line region and to derive estimates of black hole masses. Reverberation mapping results provide a fundamental low-redshift calibration for the methods used to trace the cosmological evolution of supermassive black holes. I will...   More >

Globular Clusters, Halo Stars and Galaxy Assembly

Colloquium: Astronomy Colloquia | October 8 | 4 p.m. | 1 LeConte Hall

Jean Brodie, UC Santa Cruz

Department of Astronomy

A variety of evidence suggests that metal rich globular clusters (GCs) trace the build-up of galaxy bulges, while metal poor GCs trace the build up of their halos. Wide field observations of galaxies are critically important for testing the currently favored two-phase paradigm for galaxy formation, because many signatures of galaxy assembly processes are only revealed at large radius. Indeed more...   More >

The Demographics of Exoplanets

Colloquium: Astronomy Colloquia | October 15 | 4 p.m. | 1 LeConte Hall

Scott Gaudi, Ohio State

Department of Astronomy

Measurements of the demographics of exoplanets over a range of planet and host star properties provide fundamental empirical constraints on theories of planet formation and evolution. I will discuss various efforts to measure and synthesize exoplanet demographics over broad regions of parameter space, and show results from combining microlensing, radial velocity, and direct imaging surveys to...   More >
