2016 Fall Science Colloquia
Tim Heckman (Johns Hopkins University)
I will begin by summarizing why global outflows driven from intensely star-forming galaxies are believed to play a significant role in the evolution of galaxies and the IGM. I will then review the physical mechanisms believed to be responsible for ...

2016 Fall Science Colloquia
Jennifer Lotz  (STScI)
Deep HST observations have revealed galaxies fainter than ever seen before, at look-back times when the universe was less than a billion years old. These first galaxies grow throughout cosmic time via the accretion of gas and dark matter, and via ...

2016 Fall Science Colloquia
Charles Steidel (California Institute of Technology)
Massive stars produce the most readily-observed signatures of forming galaxies at high redshift -- the FUV stellar continuum and the nebular/recombination emission excited by stellar EUV radiation field. Encoded in these spectra, which can be obs ...

2016 Fall Science Colloquia
Andrew Fox (Space Telescope Science Institute )
Gaseous inflows and outflows are key components of the life cycle of galaxies. Inflows bring in fuel for future star formation, while outflows take away the ashes from past star formation. In the Milky Way, we have a front-row seat to observe these ...

2016 Fall Science Colloquia
Nadine Neumayer (Max Planck Institute for Astronomy)
The centers of massive galaxies are special in many ways, not least because all of them are believed to host supermassive black holes. Since the discovery of a number of relations linking the mass of this central black hole to the large scale propert ...

2016 Fall Science Colloquia
Anne Marie Lagrange (Observatoire de Grenoble)
More than 3500 extrasolar planets, with masses ranging between a few Earth masses and several Jupiter masses have been found since 20 years, revealing an unexpected diversity that lead to broaden our view of planet formation and evolution processes. ...

2016 Fall Science Colloquia
Gurtina Besla (University of Arizona)
Low mass, dwarf galaxies (M* = 1e8 - 5e9 Msun) are typically gas rich, unless found in proximity to a massive host. This suggests that the evolution of dwarfs is dominated solely by their host environment, through processes such as tidal and ram pre ...

2016 Fall Science Colloquia
Beth Willman (Large Synoptic Survey Telescope)
Over the last 15 years, large sky surveys have revolutionized our view of the stellar halos and dwarf satellite populations orbiting galaxies, such as the Milky Way. Much of this observational progress has been motivated by a series of apparent “cri ...
