Special Presentations
Steven Finkelstein (The University of Texas at Austin)
Over the past two decades, the Hubble Space Telescope has frequently pushed back the high-redshift frontier, first through the epoch of galaxy assembly to z~4 and z~6 with the WFPC2/HDF and ACS/HUDF, and more recently through the epoch of reionizatio ...

Special Presentations
Brooke Simmons (UC San Diego)
Supermassive black holes and galaxies co-evolve over cosmic time, but despite more than a decade of research the engine(s) for this co-evolution are still not understood. The typical co-evolution picture invokes major galaxy mergers to both drive mat ...

Special Presentations
Vivian U (University of California, Riverside))
The tight correlations between black hole mass and the bulge properties of its host galaxy suggest that black holes and their hosts coevolve. However, the drastically different size and mass scales of these two structures make a physical explanation ...

Special Presentations
Katherine Alatalo (The Carnegie Observatories)
The morphological and color bimodalities displayed by modern-day galaxies suggest that a galaxy must have rapidly transformed from one class to the other. In the modern universe, this transition is one-way, which makes it essential to gain a census o ...

Special Presentations
Trent Dupuy (The University of Texas at Austin)
The motion of objects contains more information than emitted light alone, thus making astrometry a powerful tool for determining many astrophysical properties. I will present my work to build an empirical view of substellar evolution from unique high ...

Special Presentations
Tyler Robinson ((UC Santa Cruz))
Atmospheres are the lens through which we understand other worlds. Molecules in planetary atmospheres carve absorption features into reflection, emission, and transmission spectra, allowing us to characterize a world’s composition and thermal state. ...

Special Presentations
Larry Bradley (STScI)
One of the most exciting frontiers in observational cosmology is the characterization of the evolution of galaxies at early cosmic times. Thanks to several large surveys with the Hubble Space Telescope (HST), we have now discovered large samples of ...

Special Presentations
Erik Tollerud (STScI)
Dwarf galaxies are a frontier for new discoveries in both galaxy formation and cosmology. I will discuss work centered around connecting the ?CDM cosmology and its predictions to observations of dwarf galaxies at a variety of different scales of "dwa ...

Special Presentations
Amanda Kepley (NRAO)
Much of what we know about the process of star formation comes from observations of our own Milky Way and of nearby spiral galaxies. However, this sample only probes a relatively narrow range of galaxy properties and thus does not provide an effecti ...

Marshall Perrin (Space Telescope Science Institute)
High-contrast imaging of nearby planetary systems now allows us to directly observe both their largest and smallest components: their giant Jovian planets and the tiny planetesimals that make up dusty circumstellar disks. For planets, measurements o ...

Stephen Smartt (Queen's University Belfast)
The Pan-STARRS1 Science Consortium was formed to carry out surveys with the 7 square degree camera on the 1.8m PS1 telescope. The whole visible sky north of declination -30 degrees has been covered approximately 12 times in each of the filters gri ...

Special Presentations
Dimitrios Gouliermis (Universität Heidelberg)
Stars are born in groups at various scales and with various degrees of gravitational self-binding. These stellar clusterings host the vast majority of stars in a galaxy and feed its general field through their dissolution. They are, justifiably, the ...

Special Presentations
Dr. Angela Adamo (Max-Planck-Institut für Astronomie)
Clustering is a common feature observed in star-forming regions, caused by the fractal properties of the turbulent gas. As a result, star formation appears to be a hierarchical process, with giant molecular cloud complexes on large scales (?1 kpc), a ...

Dr. Hugues SANA (Astronomical Institute `Anton Pannekoek’ - Amsterdam University (UvA))
Through their energetic life and final explosions, massive stars exert a large influence on their environments and on their host galaxies. Massive stars are the progenitors of core-collapse supernovae and of long-duration gamma-ray bursts and their l ...

Special Presentations
Gabriel Brammer (European Southern Observatory)
The Hubble Space Telescope has given us a dazzling imaging legacy, which has enabled us to establish a broad picture across cosmic epochs of how galaxies came to be. I will present an overview and recent results of the 3D-HST survey, a 248-orbit Tre ...

Dan Coe (STScI)
The first galaxies are the frontier of extragalactic astronomy. How and when did they form, and how did they contribute to reionization? We have made progress toward answering these questions by obtaining deep infrared observations with the Hubble S ...

Special Presentations
Nicolas Lehner (Univ. of Notre Dame)
Galaxies have a voracious appetite for gas to continue to form stars over many billions of years. This gas comes from the circumgalactic medium (CGM), the interface between galaxies and the IGM, where galactic outflows and inflows collide. The ...
