Galaxies of Redshift z > 5: The View from Stony Brook
Kenneth M. Lanzetta, Hsiao-Wen Chen, Alberto Fernandez-Soto +3
We report on some aspects of our efforts to establish properties of the extremely faint galaxy population by applying our photometric redshift technique to the HDF and HDF-S WFPC2…
The Stony Brook Photometric Redshifts of Faint Galaxies in the Hubble Deep Fields
Kenneth M. Lanzetta, Hsiao-Wen Chen, Alberto Fernandez-Soto +4
We report on some aspects of the current status of our efforts to establish properties of faint galaxies by applying our photometric redshift technique to faint galaxies in the HDF…
Photometric/Spectroscopic Redshift Identification of Faint Galaxies in STIS Slitless Spectroscopy Observations
Hsiao-Wen Chen, Kenneth M. Lanzetta, Sebastian Pascarelle
We present a new spectrum extraction technique which employs optimal weights for the spectral extraction, deblends the overlapping spectra, determines the precise sky background, a…
A Spectroscopically Identified Galaxy of Probable Redshift z = 6.68
Hsiao-Wen Chen, Kenneth M. Lanzetta, Sebastian Pascarelle
The detection and identification of distant galaxies is a prominent goal of observational cosmology because distant galaxies are seen as they were in the distant past and hence pro…
Photometry and Photometric Redshifts of Galaxies in the Hubble Deep Field South Nicmos Field
Hsiao-Wen Chen, Alberto Fernandez-Soto, Kenneth M. Lanzetta +4
We present an electronic catalog of infrared and optical photometry and photometric redshifts of 323 galaxies in the Hubble Deep Field South NICMOS field at http://www.ess.sunysb.e…
Constraints on the Unseen Galaxy Population from the Lyman-alpha Forest
Kenneth M. Lanzetta, Hsiao-Wen Chen, John K. Webb +1
Here we describe results of our attempt to determine what types of galaxies are responsible for the Lyman-alpha forest absorption systems, based on our ongoing imaging and spectros…
