The Unusual Spectral Energy Distribution of a Galaxy Previously Reported to be at Redshift 6.68
Hsiao-Wen Chen, Kenneth M. Lanzetta, Sebastian Pascarelle +1
Observations of distant galaxies are important both for understanding how galaxies form and for probing the physical conditions of the universe at the earliest epochs. It is, howev…
On the Small-Scale Clustering of Ly-alpha Forest Clouds
Milan M. Cirkovic, Kenneth M. Lanzetta
Recent measurements of the autocorrelation function of the Ly-alpha clouds are analyzed from the point of view of a simple model with strong clustering on the small scales. It is s…
Morphological Number Counts and Redshift Distributions to I = 25 from the Hubble Deep Fields: Constraints on Cosmological Models from Early Type Galaxies
S. Phillipps, S. P. Driver, W. J. Couch +5
We combine magnitude and photometric redshift data on galaxies in the Hubble Deep Fields with morphological classifications in order to separate out the distributions for early typ…
On the compared accuracy and reliability of spectroscopic and photometric redshift measurements
Alberto Fernandez-Soto, Kenneth M. Lanzetta, Hsiao-Wen Chen +2
We present a comparison between the spectroscopic catalog of the HDF recently published by Cohen et al and the redshifts measured by our group for those objects using photometric t…
Photometry and Photometric Redshifts of Faint Galaxies in the Hubble Deep Field South NICMOS Field
Noriaki Yahata, Kenneth M. Lanzetta, Hsiao-Wen Chen +4
We present a catalog of photometry and photometric redshifts of 335 faint objects in the HDF-S NICMOS field. The analysis is based on (1) infrared images obtained with the Hubble S…
