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…
The Ultraviolet Luminosity Density of the Universe from Photometric Redshifts of Galaxies in the Hubble Deep Field
Sebastian M. Pascarelle, Kenneth M. Lanzetta, Alberto Fernandez-Soto
Studies of the Hubble Deep Field (HDF) and other deep surveys have revealed an apparent peak in the ultraviolet (UV) luminosity density, and therefore the star-formation rate densi…
