Andrei Mesinger (Princeton University)
It is generally taken for granted that reionization has completed by z=6, due to the detection of flux in the Lyman alpha forest at redshifts z<6. However, since reionization is expected to be highly inhomogeneous, much of the spectra pass through ju ...
2010 Hubble Fellows Symposium (20th Anniversary)
Jonathan Pritchard (Harvard-Smithsonian Center for Astrophysics)
One of the major unanswered questions surrounding the period of the first sources is how the Universe became reionized. In this talk, I will discuss the extent to which existing observations of the cosmic microwave background and the lyman alpha fore ...

2010 Hubble Fellows Symposium (20th Anniversary)
Mark Ammons (University of Arizona)
AGN feedback may contribute to quenching of star formation by the expulsion or heating of cold gas, causing the host galaxy to evolve onto the red sequence (e.g., Di Matteo et al. 2005, Hopkins et al. 2006). We probe for the effects of feedback on t ...
2010 Hubble Fellows Symposium (20th Anniversary)
Misty Bentz (University of California, Irvine)
A defining spectral characteristic of bright AGNs is their extremely broad permitted emission lines. This emission is theorized to originate very close to the central supermassive black hole, on scales of ~0.001 pc (comparable in size to the Solar Sy ...
2010 Hubble Fellows Symposium (20th Anniversary)
Elena Gallo (MIT)
An issue of fundamental importance in understanding the galaxy-black hole connection is the duty cycle of accretion. If black holes are indeed ubiquitous in galactic nuclei, little is known about the frequency and intensity of their activity, the mor ...
