2012 Science Colloquia
Emily Levesque (Department of Astrophysical & Planetary Sciences, University of Colorado, Boulder)
Models of stellar evolution play a key role in a wide variety of research areas within astrophysics, including galaxy evolution, the properties of the first stars, supernova and GRB progenitor studies, and the hosts of extrasolar planets. Among their ...

2012 Science Colloquia
Pieter van Dokkum  (Department of Astronomy, Yale University)
Owing to large surveys with the Hubble Space Telescope and ground-based telescopes we now have high resolution snapshots of the Universe dating back to only a few hundred million years after the Big Bang. The challenge now is to use this wealth of da ...

2012 Science Colloquia
Joe Silk  (Department of Physics, University of Oxford)
Progress has been made in understanding the origin of spiral galaxies, but elliptical galaxy formation continues to pose unresolved problems. In both cases, feedback seems to be a central issue. I will review our understanding of feedback, on scal ...

2012 Science Colloquia
Samir Salim (Indiana University )
Abstract: Early-type galaxies are generally considered to be old and passive systems, having no current star formation (SF). In this talk I show how UV observations have revealed that a significant fraction of field galaxies on the red sequence exhi ...

2012 Science Colloquia
Annika Peter (Department of Physics and Astronomy, University of California, Irvine)
The nature of dark matter is one of the major "known unknowns" of physics of the universe. From astronomical observations, we know that dark matter exists, makes up 23% of the mass budget of the universe, clusters strongly to form the load-bearing f ...

The Herschel Space Observatory, an ESA cornerstone mission with NASA participation, has been in operation for over two years. I will briefly outline the overall capabilities of Herschel which has both photometric and spectroscopic coverage from 63 ...

2012 Science Colloquia
Warren Brown (Smithsonian Astrophysical Observatory)
A massive black hole sits in the heart of the Milky Way. One consequence of the black hole is that it ejects "hypervelocity stars" from the Milky Way at ~1000 km/s velocities. We discovered the first hypervelocity star in 2005, and since then our t ...

2012 Science Colloquia
James Lloyd  (Cornell University)
Studies of the planet abundance as a function of stellar mass have shown a strong increase in the frequency of planet occurrence around stars more massive than 1.5 Msun, and that such stars are deficit in short period planets. These planet searches ...

2012 Science Colloquia
Piero Rosati  (ESO)
I will briefly review how multi-wavelength studies of distant galaxy clusters can set important constraints on structure formation and cosmological scenarios. Their mass function out to z>1 and the study of their dark matter mass density profiles ...

Bethany Johns (AAS Bahcall Fellow)
Abstract: Federal budget cuts, deficit spending, raising the debt ceiling, mandatory spending, fiscal responsibility, balancing the budget – these phrases are guiding much of the debate on Capitol Hill and the 2012 election campaigns. This rhetori ...
