Finding Clusters of Galaxies in the Sloan Digital Sky Survey using Voronoi Tessellation
Rita S. J. Kim, Michael A. Strauss, Neta A. Bahcall +5
The Sloan Digital Sky Survey has obtained 450 square degrees of photometric scan data, in five bands (u',g',r',i',z'), which we use to identify clusters of galaxies. We illustrate…
Weak Lensing with SDSS Commissioning Data: The Galaxy-Mass Correlation Function To 1/h Mpc
SDSS Collaboration, Fischer
(abridged) We present measurements of galaxy-galaxy lensing from early commissioning imaging data from the Sloan Digital Sky Survey (SDSS). We measure a mean tangential shear aroun…
High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data II: The Spring Equatorial Stripe
SDSS Collaboration, Xiaohui Fan
This is the second paper in a series aimed at finding high-redshift quasars from five-color (u'g'r'i'z') imaging data taken along the Celestial Equator by the Sloan Digital Sky Sur…
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…
The Cosmic Triangle: Revealing the State of the Universe
N. Bahcall, J. P. Ostriker, S. Perlmutter +1
The "cosmic triangle" is introduced as a way of representing the past, present, and future status of the universe. Our current location within the cosmic triangle is determined by…
A Model-Independent Photometric Redshift Estimator
Yun Wang, Neta Bahcall, Edwin L. Turner
We derive a simple empirical photometric redshift estimator using a training set of galaxies with multiband photometry and measured redshifts in the Hubble Deep Field (HDF). This e…
High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data
SDSS Collaboration, X. Fan
We present photometric and spectroscopic observations of 15 high-redshift quasars (z > 3.6) discovered from ~140 deg^2 of five-color (u'g'r'i'z') imaging data taken by the Sloan Di…
Cosmology with Clusters of Galaxies
Neta A. Bahcall
I show that three independent methods utilizing clusters of galaxies - cluster dynamics and mass-to-light ratio, baryon fraction in clusters, and cluster evolution - all indicate t…
