A Model-Independent Method of Determining Energy Scale and Muon Number in Cosmic Ray Surface Detectors
Fabian Schmidt, Maximo Ave, Lorenzo Cazon +1
Surface detector arrays are designed to measure the spectrum and composition of high-energy cosmic rays by detecting the secondary particle flux of the Extensive Air Showers (EAS)…
Environmental Effects on Real-Space and Redshift-Space Galaxy Clustering
Ying Zu, Zheng Zheng, G. T. Zhu +1
Galaxy formation inside dark matter halos, as well as the halo formation itself, can be affected by large-scale environments. Evaluating the imprints of environmental effects on ga…
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
Upper limit on the diffuse flux of UHE tau neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau-neutrinos that interact in the Earth's crust. Tau leptons from charged-cur…
An analytic model for the bispectrum of galaxies in redshift space
Robert E. Smith, Ravi K. Sheth, Roman Scoccimarro
We develop an analytic theory for the redshift space bispectrum of dark matter, haloes and galaxies. This is done within the context of the halo model of structure formation, as th…
Maximum Likelihood Method for Cross Correlations with Astrophysical Sources
Ronnie Jansson, Glennys R. Farrar
We generalize the Maximum Likelihood-type method used to study cross correlations between a catalog of candidate astrophysical sources and Ultrahigh Energy Cosmic Rays (UHECRs), to…
The Galaxy Content of SDSS Clusters and Groups
Sarah M. Hansen, Erin S. Sheldon, Risa H. Wechsler +1
Imaging data from the Sloan Digital Sky Survey are used to characterize the population of galaxies in groups and clusters detected with the MaxBCG algorithm. We investigate the dep…
Large-Angular-Scale Clustering as a Clue to the Source of UHECRs
Andreas A. Berlind, Glennys R. Farrar
We show that future Ultra-High Energy Cosmic Ray samples should be able to distinguish whether the sources of UHECRs are hosted by galaxy clusters or ordinary galaxies, or whether…
Cleaning the USNO-B Catalog through automatic detection of optical artifacts
Jonathan T. Barron, Christopher Stumm, David W. Hogg +2
The USNO-B Catalog contains spurious entries that are caused by diffraction spikes and circular reflection halos around bright stars in the original imaging data. These spurious en…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters III: Mass-to-light Ratios
Erin S. Sheldon, David E. Johnston, Morad Masjedi +8
We present measurements of the excess mass-to-light ratio measured aroundMaxBCG galaxy clusters observed in the SDSS. This red sequence cluster sample includes objects from small g…
Measuring the mean and scatter of the X-ray luminosity -- optical richness relation for maxBCG galaxy clusters
E. S. Rykoff, T. A. McKay, M. R. Becker +6
Determining the scaling relations between galaxy cluster observables requires large samples of uniformly observed clusters. We measure the mean X-ray luminosity--optical richness (…
Cross-correlation Weak Lensing of SDSS Galaxy Clusters I: Measurements
Erin S. Sheldon, David E. Johnston, Ryan Scranton +12
This is the first in a series of papers on the weak lensing effect caused by clusters of galaxies in Sloan Digital Sky Survey. The photometrically selected cluster sample, known as…
The growth of luminous red galaxies by merging
Morad Masjedi, David W. Hogg, Michael R. Blanton
We study the role of major and minor mergers in the mass growth of luminous red galaxies. We present small-scale ($0.01<r<8\,\hMpc$) projected cross-correlation functions of $23043…
Large scale magnetic field of the Milky Way from WMAP3 data
Ronnie Jansson, Glennys R. Farrar, Andre Waelkens +1
We report on initial results from a project to constrain the large-scale and turbulent magnetic fields of the Milky Way galaxy, which eventually will incorporate all of the relevan…
Maximum Likelihood method for ultrahigh energy cosmic ray cross correlations with astrophysical sources
Ronnie Jansson, Glennys R. Farrar
We extend the Maximum Likelihood method used by HiRes to study cross correlations between a catalog of candidate astrophysical sources and Ultrahigh Energy Cosmic Rays (UHECRs), to…
Star Formation in NGC 5194 (M51a). II. The Spatially-Resolved Star Formation Law
Robert C. Kennicutt, Daniela Calzetti, Fabian Walter +20
We have studied the relationship between the star formation rate (SFR) surface density and gas surface density in the spiral galaxy M51a (NGC 5194), using multi-wavelength data obt…
The Sloan Digital Sky Survey Quasar Lens Search. II. Statistical Lens Sample from the Third Data Release
Naohisa Inada, Masamune Oguri, Robert H. Becker +31
We report the first results of our systematic search for strongly lensed quasars using the spectroscopically confirmed quasars in the Sloan Digital Sky Survey (SDSS). Among 46,420…
The Sloan Digital Sky Survey Quasar Lens Search. III. Constraints on Dark Energy from the Third Data Release Quasar Lens Catalog
Masamune Oguri, Naohisa Inada, Michael A. Strauss +31
We present cosmological results from the statistics of lensed quasars in the Sloan Digital Sky Survey (SDSS) Quasar Lens Search. By taking proper account of the selection function,…
Cosmological Constraints on Radion Evolution in the Universal Extra Dimension Model
K. C. Chan, M. -C. Chu
The constraints on the radion evolution in the Universal Extra Dimension (UED) model from Cosmic Microwave Background (CMB) and Type Ia supernovae (SNe Ia) data are studied. In the…
A Galaxy Photometric Redshift Catalog for the Sloan Digital Sky Survey Data Release 6
Hiroaki Oyaizu, Marcos Lima, Carlos E. Cunha +3
We present and describe a catalog of galaxy photometric redshifts (photo-z's) for the Sloan Digital Sky Survey (SDSS) Data Release 6 (DR6). We use the Artificial Neural Network (AN…
Testing cold dark matter with the low mass Tully-Fisher relation
Michael R. Blanton, Marla Geha, Andrew A. West
The galaxy circular velocity function at small masses is related to the matter power spectrum on small scales. Although this function is well-studied for Local Group dwarfs, theore…
The Fifth Data Release of the Sloan Digital Sky Survey
Jennifer K. Adelman-McCarthy
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
Magnetically-dominated jets inside collapsing stars as a model for gamma-ray bursts and supernova explosions
Dmitri A. Uzdensky, Andrew I. MacFadyen
It has been suggested that magnetic fields play a dynamically-important role in core-collapse explosions of massive stars. In particular, they may be important in the collapsar sce…
