After the Dark Ages: the Evolution of Luminous Sources at z<5
Piero Madau
I review recent observational and theoretical progress in our understanding of the cosmic evolution of luminous sources. Through a combination of deep imaging, Keck spectroscopy, a…
Gravitational Lensing of Distant Supernovae in Cold Dark Matter Universes
Cristiano Porciani, Piero Madau
Ongoing searches for supernovae (SNe) at cosmological distances have recently started to provide large numbers of events with measured redshifts and apparent brightnesses. Compared…
An Extremely Red r^{1/4} Galaxy in the Test Image of the Hubble Deep Field South
T. Treu, M. Stiavelli, A. R. Walker +14
We report the serendipitous discovery of an extremely red object in the Hubble Deep Field South (HDFS) Test NICMOS (Near Infrared Camera and Multi Object Spectrograph) field of vie…
Probing The High Redshift Universe with the NGST
Piero Madau
Through a combination of deep wide-field imaging and multi-object spectroscopy, the Next Generation Space Telescope will be able to chart with unprecedented accuracy the evolution…
Star Formation at High Redshift: A Population of Early Dwarfs?
Piero Madau
The history of the transition from a neutral intergalactic medium (IGM) to one that is almost fully ionized can reveal the character of cosmological ionizing sources and set import…
What Keeps the Universe Ionized at z=5?
Piero Madau
The history of the transition from a neutral intergalactic medium to one that is almost fully ionized can reveal the character of cosmological ionizing sources. In this talk I will…
