We present new results of our program to systematically search for strongly lensed galaxies in the Sloan Digital Sky Survey (SDSS) imaging data. In this study six strong lens syste…
A novel method for the absolute fluorescence yield measurement by AIRFLY
AIRFLY Collaboration, M. Ave
One of the goals of the AIRFLY (AIR FLuorescence Yield) experiment is to measure the absolute fluorescence yield induced by electrons in air to better than 10% precision. We introd…
Nucleosynthetic osmium isotope anomalies in acid leachates of the Murchison meteorite
L. Reisberg, N. Dauphas, A. Luguet +3
We present osmium isotopic results obtained by sequential leaching of the Murchison meteorite, which reveal the existence of very large internal anomalies of nucleosynthetic origin…
Backgrounds and Projected Limits from Dark Matter Direct Detection Experiments
Scott Dodelson
A simple formula is introduced which indicates the amount by which projections of dark matter direct detection experiments are expected to be degraded due to backgrounds.
Reconstructing Patchy Reionization from the Cosmic Microwave Background
Cora Dvorkin, Kendrick M. Smith
We introduce a new statistical technique for extracting the inhomogeneous reionization signal from future high-sensitivity measurements of the cosmic microwave background temperatu…
The Seventh Data Release of the Sloan Digital Sky Survey
K. Abazajian
This paper describes the Seventh Data Release of the Sloan Digital Sky Survey (SDSS), marking the completion of the original goals of the SDSS and the end of the phase known as SDS…
Non-linear Evolution of f(R) Cosmologies III: Halo Statistics
Fabian Schmidt, Marcos Lima, Hiroaki Oyaizu +1
The statistical properties of dark matter halos, the building blocks of cosmological observables associated with structure in the universe, offer many opportunities to test models…
Distinguishing Between Dark Matter and Pulsar Origins of the ATIC Electron Spectrum With Atmospheric Cherenkov Telescopes
Jeter Hall, Dan Hooper
Recent results from the Advanced Thin Ionization Calorimeter (ATIC) balloon experiment have identified the presence of a spectral feature between approximately 300 and 800 GeV in t…
Magnetic acceleration of ultra-relativistic jets in gamma-ray burst sources
Serguei Komissarov, Nektarios Vlahakis, Arieh Konigl +1
We present a relativistic-MHD numerical study of axisymmetric, magnetically driven jets with parameters applicable to gamma-ray burst (GRB) flows. We also present analytic expressi…
Gamma ray emission and stochastic particle acceleration in galaxy clusters
G. Brunetti, P. Blasi, R. Cassano +1
FERMI (formely GLAST) will shortly provide crucial information on relativistic particles in galaxy clusters. We discuss non-thermal emission in the context of general calculations…
CMBPol Mission Concept Study: Probing Inflation with CMB Polarization
Daniel Baumann, Mark G. Jackson, Peter Adshead +56
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of inflation. We focus on the prospects for using CMB measu…
IRAS-based whole-sky upper limit on Dyson Spheres
Richard A. Carrigan
A Dyson Sphere is a hypothetical construct of a star purposely cloaked by a thick swarm of broken-up planetary material to better utilize all of the stellar energy. A clean Dyson S…
The 2dF-SDSS LRG and QSO Survey: The spectroscopic QSO catalogue
Scott M. Croom, Gordon T. Richards, Tom Shanks +27
We present the final spectroscopic QSO catalogue from the 2dF-SDSS LRG and QSO (2SLAQ) Survey. This is a deep, 18<g<21.85 (extinction corrected), sample aimed at probing in detail…
Lessons Learned from Sloan Digital Sky Survey Operations
S. J. Kleinman, J. E. Gunn, B. Boroski +12
Astronomy is changing. Large projects, large collaborations, and large budgets are becoming the norm. The Sloan Digital Sky Survey (SDSS) is one example of this new astronomy, and…
A Catalog of Broad Absorption Line Quasars in Sloan Digital Sky Survey Data Release 5
Robert R. Gibson, Linhua Jiang, W. N. Brandt +9
We present a catalog of 5039 broad absorption line (BAL) quasars (QSOs) in the Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) QSO catalog that have absorption troughs coverin…
Modeling Molecular Hydrogen and Star Formation in Cosmological Simulations
Nickolay Y. Gnedin, Konstantinos Tassis, Andrey V. Kravtsov
We describe a phenomenological model for molecular hydrogen formation suited for applications in galaxy formation simulations, which includes on-equilibrium formation of molecular…
Galaxy clusters discovered with a Sunyaev-Zel'dovich effect survey
Z. Staniszewski, P. A. R. Ade, K. A. Aird +41
The South Pole Telescope (SPT) is conducting a Sunyaev-Zel'dovich (SZ) effect survey over large areas of the southern sky, searching for massive galaxy clusters to high redshift. I…
Pulsars as the Sources of High Energy Cosmic Ray Positrons
Dan Hooper, Pasquale Blasi, Pasquale Dario Serpico
Recent results from the PAMELA satellite indicate the presence of a large flux of positrons (relative to electrons) in the cosmic ray spectrum between approximately 10 and 100 GeV.…
Gamma ray emission from SNR RX J1713.7-3946 and the origin of galactic cosmic rays
G. Morlino, E. Amato, P. Blasi
We calculate the flux of non-thermal radiations from the supernova remnant RX J1713.7-3946 in the context of the non-linear theory of particle acceleration at shocks, which allows…
