The Discovery of a High-redshift Quasar without Emission Lines from Sloan Digital Sky Survey Commissioning Data
SDSS Collaboration, Xiaohui Fan
We report observations of a luminous unresolved object at redshift z = 4.62, with a featureless optical spectrum redward of the Lyman alpha forest region, discovered from Sloan Dig…
L Dwarfs Found in Sloan Digital Sky Survey Commissioning Imaging Data
SDSS Collaboration, Xiaohui Fan
This paper describes the discovery of seven dwarf objects of spectral type `L' (objects cooler than the latest M dwarfs) in commissioning imaging data taken by the Sloan Digital Sk…
The Discovery of a Field Methane Dwarf from Sloan Digital Sky Survey Commissioning Data
SDSS Collaboration, Michael A. Strauss
We report the discovery of the coolest field dwarf yet known, selected as a stellar object with extremely red colors from commissioning imaging data of the Sloan Digital Sky Survey…
Deep Intermediate-Band Surface Photometry of NGC 5907
BATC Collaboration, Z. Y. Zheng, Z. H. Shang +3
We obtained very deep exposures of NGC 5907 with a Schmidt telescope, large-format CCD, and intermediate-band filters centered at 6660A and 8020A. These two filters, part of a 15-f…
Simulation of Stellar Objects in SDSS Color Space
Xiaohui Fan
We present a simulation of the spatial, luminosity and spectral distributions of four types of stellar objects. We simulate: (1) Galactic stars, based on a Galactic structure model…
