Discovery of Two Gravitationally Lensed Quasars with Image Separations of 3 Arcseconds from the Sloan Digital Sky Survey
Masamune Oguri, Naohisa Inada, Joseph F. Hennawi +15
We report the discovery of two doubly-imaged quasars, SDSS J100128.61+502756.9 and SDSS J120629.65+433217.6, at redshifts of 1.838 and 1.789 and with image separations of 2.86'' an…
Variable stars as standard candles and stellar tracers
G. Bono, M. Cignoni
We review the current status of classical Cepheid and RR Lyrae distance scales. We discuss the most recent theoretical and empirical findings together with pros and cons of differe…
Isocurvature constraints on gravitationally produced superheavy dark matter
Daniel J. H. Chung, Edward W. Kolb, Antonio Riotto +1
We show that the isocurvature perturbations imply that the gravitationally produced superheavy dark matter must have masses larger than few times the Hubble expansion rate at the e…
Toward Understanding Environmental Effects in SDSS Clusters
J. Einasto, E. Tago, M. Einasto +5
We find clusters and superclusters of galaxies using the Data Release 1 of the Sloan Digital Sky Survey. We determine the luminosity function of clusters and find that clusters in…
The Nonlinear Cosmological Matter Power Spectrum with Massive Neutrinos I: The Halo Model
Kevork Abazajian, Eric R. Switzer, Scott Dodelson +2
Measurements of the linear power spectrum of galaxies have placed tight constraints on neutrino masses. We extend the framework of the halo model of cosmological nonlinear matter c…
A new method of measuring the peculiar velocity power spectrum
Pengjie Zhang, Albert Stebbins, Roman Juszkiewicz +1
We show that by directly correlating the cluster kinetic Sunyaev Zeldovich (KSZ) flux, the cluster peculiar velocity power spectrum can be measured to accuracy by future…
Curvature Perturbations from Broken Symmetries
Edward W. Kolb, Antonio Riotto, Alberto Vallinotto
We present a new general mechanism to generate curvature perturbations after the end of the slow-roll phase of inflation. Our model is based on the simple assumption that the poten…
A comprehensive model for the Monoceros tidal stream
J. Penarrubia, D. Martinez-Delgado, H. W. Rix +7
We have compiled an extensive dataset on potential parts of the Monoceros tidal stream and performed an exhaustive survey of dwarf galaxy semi-analytic orbits in order to constrain…
Optimizing the yield of Sunyaev-Zel'dovich cluster surveys
Richard A. Battye, Jochen Weller
We consider the optimum depth of a cluster survey selected using the Sunyaev-Zel'dovich effect. By using simple models for the evolution of the cluster mass function and detailed m…
The Third Data Release of the Sloan Digital Sky Survey
K. Abazajian et al.
This paper describes the Third Data Release of the Sloan Digital Sky Survey (SDSS). This release, containing data taken up through June 2003, includes imaging data in five bands ov…
SDSS Data Management and Photometric Quality Assessment
Z. Ivezic, R. H. Lupton, D. Schlegel +24
We summarize the Sloan Digital Sky Survey data acquisition and processing steps, and describe runQA, a pipeline designed for automated data quality assessment. In particular, we sh…
A Catalog of Very Isolated Galaxies from the SDSS Data Release 1
Sahar S. Allam, Douglas L. Tucker, Brian C. Lee +1
We present a new catalog of isolated galaxies obtained through an automated systematic search. These 2980 isolated galaxies were found in approximately 2099 sq deg of sky in the Sl…
Cosmological influence of super-Hubble perturbations
Edward W. Kolb, Sabino Matarrese, Alessio Notari +1
The existence of cosmological perturbations of wavelength larger than the Hubble radius is a generic prediction of the inflationary paradigm. We provide the derivation beyond pertu…
Measurement of Galaxy Cluster Sizes, Radial Profiles, and Luminosity Functions from SDSS Photometric Data
Sarah M. Hansen, Timothy A. McKay, Risa H. Wechsler +3
Imaging data from the Sloan Digital Sky Survey is used to measure the empirical size-richness relation for a large sample of galaxy clusters. Using population subtraction methods,…
A New Milky Way Companion: Unusual Globular Cluster or Extreme Dwarf Satellite?
Beth Willman, Michael R. Blanton, Andrew A. West +6
We report the discovery of SDSSJ1049+5103, an overdensity of resolved blue stars at (α_{2000}, δ_{2000}) = (162.343, 51.051). This object appears to be an old, metal-poor stellar s…
Cosmological Lepton Asymmetry, Primordial Nucleosynthesis, and Sterile Neutrinos
Kevork Abazajian, Nicole F. Bell, George M. Fuller +1
We study post weak decoupling coherent active-sterile and active-active matter-enhanced neutrino flavor transformation in the early universe. We show that flavor conversion efficie…
The Cosmology of Generalized Modified Gravity Models
Sean M. Carroll, Antonio De Felice, Vikram Duvvuri +3
We consider general curvature-invariant modifications of the Einstein-Hilbert action that become important only in regions of extremely low space-time curvature. We investigate the…
Sloan Digital Sky Survey Imaging of Low Galactic Latitude Fields: Technical Summary and Data Release
Douglas P. Finkbeiner, Nikhil Padmanabhan, David J. Schlegel
The Sloan Digital Sky Survey (SDSS) mosaic camera and telescope have obtained five-band optical-wavelength imaging near the Galactic plane outside of the nominal survey boundaries.…
Gamma-Ray Constraint on Galactic Positron Production by MeV Dark Matter
John F. Beacom, Nicole F. Bell, Gianfranco Bertone
The Galactic positrons, as observed by their annihilation gamma-ray line at 0.511 MeV, are difficult to account for with astrophysical sources. It has been proposed that they are p…
Uncertainties in the S-Z selected cluster angular power spectrum
J. D. Cohn, Kenji Kadota
Large SZ selected galaxy cluster surveys are beginning imminently. We compare the dependence of the galaxy cluster angular power spectrum on cosmological parameters, different mode…
Constraining Dark Energy with X-ray Galaxy Clusters, Supernovae and the Cosmic Microwave Background
David Rapetti, Steven W. Allen, Jochen Weller
We present new constraints on the evolution of dark energy from an analysis of Cosmic Microwave Background, supernova and X-ray galaxy cluster data. Our analysis employs a minimum…
Mass-producing spectra: The SDSS spectrographic system
Peter R. Newman, Dan C. Long, Stephanie A. Snedden +8
The Sloan Digital Sky Survey is the largest redshift survey conducted to date, and the principal survey observations have all been conducted on the dedicated SDSS 2.5m and 0.5m tel…
