2017 Fall Science Colloquia
Gilles Fontaine (University of Montreal)
A few years ago, Charpinet, Fontaine, & Brassard (2009, Nature, 461, 501) developed a new approach to test for solid body rotation (and deviations thereof) in pulsating stars. The method was successfully applied to the prototype of the GW Vir class o ...

Mark Vogelsberger (Massachusetts Institute of Technology)
In my talk I will describe recent efforts to model the large-scale distribution of galaxies with cosmological hydrodynamics simulations. I will focus on the Illustris simulation, and our new simulation campaign, the IllustrisTNG project. After demon ...

STScI Public Lecture Series
Kelsey Glazer (Towson University)
A double dose of cosmic considerations, presented by the first undergraduate guest speaker in this series! Begin with the simple, yet deep, question of "why is the night sky dark?" This classic conundrum was raised two centuries ago because it ...

STScI Astrobiology Lecture Series
Kevin Peter Hand (NASA/Jet Propulsion Lab/Caltech)
Where is the best place to find living life beyond Earth? It may be that the small, ice-covered moons of Jupiter and Saturn harbor some of the most habitable real estate in our Solar System. Life loves liquid water and these moons have lots of it! Dr ...

2017 Fall Science Colloquia
Blakesley Burkhart (Harvard-Smithsonian Center for Astrophysics)
Our current view of the interstellar medium (ISM) is as a multiphase environment where turbulence affects many key processes. These include star formation, cosmic ray acceleration, and the evolution of structure in the diffuse ISM. It is therefore es ...

2017 Fall Science Colloquia
Ian Roederer (University of Michigan)
: NASA's Cosmic Origins program aims to address the question, "How did we get here?" My work addresses this question through three broad themes: the nature of the first stars, the formation and evolution of the Milky Way and Local Group, and the ori ...

Caitlin Casey (University of Texas)
Although rare in the nearby Universe, galaxies with extraordinary star-formation rates (100-1000x the Milky Way at >100 Msun/year) represent the typical massive galaxy in the early Universe ~10 billion years ago. These galaxies’ high star-formation ...

2017 Fall Science Colloquia
Megan Donahue  (Michigan State University )
One of the biggest challenges to understanding how galaxies work is decoding the role of the central supermassive black hole. Without feedback from the black hole (“AGN feedback”), galaxy evolution models fail to produce realistic massive galaxies an ...

Kirill Tchernyshyov  (JHU)
There is general agreement that the ISM of the Milky Way is arranged into a spiral-like pattern of some sort, though there is not yet agreement on how regular this spiral-like pattern is or how it evolves. To investigate this and other questions rela ...

Dominika Wylezalek (JHU)
Feedback from accreting supermassive black holes is now a standard ingredient in galaxy formation models. But while many compelling models of AGN feedback exist, there is no clear data-driven picture of how AGN-driven winds are launched, how they pro ...

Ben Sargent  (Space Telescope Science Institute)
The asymptotic giant branch (AGB) phase is one of the last phases of a star’s life. AGB stars lose mass in an outflow in which dust condenses and is pushed away from the star. Extreme AGB stars are so named because their very red colors suggest ver ...
