2007 Hubble Fellows Symposium
Mark Krumholz  (n/a)
The physical mechanism by which massive stars form is one of the outstanding problems in astrophysics, but one that has seen much recent progress thanks to an influx of new data. In the last few years, millimeter interferometers have revealed a popul ...
2007 Hubble Fellows Symposium
Klaus Pontoppidan  (n/a)
The dynamics and chemistry of molecular gas in the inner few tens of AU in proto-planetary disks are crucial for understanding the process of planet formation as well as the initial chemical conditions on the surfaces of Earth-like planets. I will de ...
2007 Hubble Fellows Symposium
Eric Ford  (n/a)
For centuries, knowledge of planetary systems and ideas about planet formation were based on a single example, our solar system. The first discoveries of extrasolar planets revealed a wide diversity of planetary systems, including surprising planets ...
2007 Hubble Fellows Symposium
Gaspar Bakos  (n/a)
I will review the current status of the search for extrasolar planets around nearby, bright stars with the HAT Network of small, automated telescopes. I will talk about our discovery, planet HAT-P-1b, and will hint on other candidates we have in the ...
2007 Hubble Fellows Symposium
Anjum Mukadam  (n/a)
Agile is a portable high-speed time-series photometer, based on the Princeton Instruments VersArray CCD camera, designed to study blue variables. A time-series photometer requires a precise measurement of both the start time of an exposure and the e ...

2007 Hubble Fellows Symposium
Christy Tremonti  (n/a)
Feedback from massive stars and accreting black holes has proven to be a key ingredient in successful models of galaxy evolution. Yet much about the feedback process is still poorly understood due to a lack of direct observational constraints. To hel ...
2007 Hubble Fellows Symposium
Aristotle Socrates  (n/a)
In terms of their energetics, interstellar cosmic rays are an insignificant by-product of star formation. However, due to their small mean free path, their coupling with interstellar gas is absolute in that they are the dominant source of momentum de ...
2007 Hubble Fellows Symposium
Janice Lee  (n/a)
An outstanding question in galaxy evolution is whether the star formation histories of low mass systems are preferentially dominated by global starbursts or modes that are more quiescent and continuous. In this talk, I will quantify the prevalence of ...
2007 Hubble Fellows Symposium
Jason Kalirai  (n/a)
We present one of the deepest optical images ever taken with the Hubble Space Telescope Advanced Camera for Surveys, a 126 orbit integration of a small field within the second nearest Galactic globular cluster NGC 6397. The data set allows us to con ...
2007 Hubble Fellows Symposium
Rachel Osten  (n/a)
The transition region in late-type stellar atmospheres serves to separate the chromosphere from the tenuous corona. It is important for understanding the dynamics and structuring occurring in the outer atmospheres of stars. Transition region emission ...
2007 Hubble Fellows Symposium
Jeong-Eun Lee  (n/a)
Jeong-Eun Lee Two recent solar wind oxygen isotope measurements have yielded dramatically different results, in one case showing a mass-independent signature of Delta 17O_SMOW ~ -20 permil and in the other case +20 permil for the Sun. In this tal ...
2007 Hubble Fellows Symposium
Scott Sheppard (n/a)
Several large dwarf planet type objects have recently been discovered beyond Neptune. These objects are important because they are the brightest and thus easiest objects to observe in the Trans-Neptunian region. This allows the use of a variety of ob ...
2007 Hubble Fellows Symposium
Niccolo Bucciantini  (n/a)
Relativistic flows play are often invoked as the key element in many high energy astrophysical phenomena. Their complexity, and the richness of their interaction with the surrounding medium have stated to be investigated only recently thanks to the i ...
2007 Hubble Fellows Symposium
Seth Redfield  (n/a)
The local interstellar medium (LISM) provides an opportunity to study general ISM processes in great detail and in three dimensions, as well as observe how stellar and planetary systems interact with their surrounding interstellar environment (e.g., ...

2007 Hubble Fellows Symposium
Hiranya Peiris  (n/a)
Much theoretical and experimental effort is currently being devoted to investigating "dark energy", a mysterious component that contributes about 75% of the total energy density in the universe and causes its expansion to accelerate. Virtually nothin ...
2007 Hubble Fellows Symposium
Kris Sigurdson  (n/a)
We discuss a model independent study of resonant photon scattering off dark matter (DM) particles. The DM particle chi_1 can feature an electric or magnetic transition dipole moment which couples it with photons and a heavier neutral particle chi_2. ...
2007 Hubble Fellows Symposium
Juerg Diemand (n/a)
Massive supercomputer simulations now allow to follow the formation and evolution of CDM halos and their subhalo population in detail. We have recently completed the "Via Lactea" run: It resolves a Milky Way scale halo with over 200 million particles ...
2007 Hubble Fellows Symposium
Masami Ouchi  (n/a)
I will present the progress of our wide-field deep surveys for dropout galaxies and Lya emitters (LAEs) at z=3-9 in the Subaru and GOODS fields. Based on the narrow-band images in the Subaru fields, we have identified 1100 Lya emitters from z=3.10 up ...
2007 Hubble Fellows Symposium
Joseph Hennawi  (University of California, Berkeley)
I will describe a search technique for finding quasars at distances of < 300 kpc from galaxies with large column densities of neutral hydrogen at high redshift. At these small separations, the ionizing flux from a quasar could be as large as ~ 10,000 ...
2007 Hubble Fellows Symposium
Alison Coil  (n/a)
Changes in galaxy and quasar clustering properties with time reflect both evolution in the dark matter halo distribution and galaxy and quasar evolution and are key diagnostics for theoretical models. I will highlight recent results on the color-dep ...
2007 Hubble Fellows Symposium
Zheng Zheng  (n/a)
Luminous red galaxies (LRGs) constitute the bright end of the galaxy luminosity function. Their clustering properties encode information about their environment, formation, and evolution, which can provide a crucial test of theories of galaxy formati ...

2007 Hubble Fellows Symposium
Nikhil Padmanabhan  (n/a)
I will introduce a new class of estimators of the correlation function that attempt to minimize various systematic effects. These allow a direct comparison with theory, without modeling redshift space distortions and the large scale correlation funct ...
