Search for dark matter annihilations in the Sun with the 79-string IceCube detector
IceCube collaboration, M. G. Aartsen, R. Abbasi +274
We have performed a search for muon neutrinos from dark matter annihilation in the center of the Sun with the 79-string configuration of the IceCube neutrino telescope. For the fir…
Atmospheric extinction properties above Mauna Kea from the Nearby Supernova Factory spectro-photometric data set
C. Buton, Y. Copin, G. Aldering +30
We present a new atmospheric extinction curve for Mauna Kea spanning 3200--9700 Å. It is the most comprehensive to date, being based on some 4285 standard star spectra obtained on…
A Search for New Candidate Super-Chandrasekhar-Mass Type Ia Supernovae in the Nearby Supernova Factory Dataset
The Nearby Supernova Factory, :, R. Scalzo +32
We present optical photometry and spectroscopy of five type Ia supernovae discovered by the Nearby Supernova Factory selected to be spectroscopic analogues of the candidate super-C…
Critical fluctuations of the proton density in A+A collisions at GeV
T. Anticic, B. Baatar, D. Barna +71
We look for fluctuations expected for the QCD critical point using an intermittency analysis in the transverse momentum phase space of protons produced around midrapidity in the 12…
An improved method for measuring muon energy using the truncated mean of dE/dx
IceCube collaboration, R. Abbasi, Y. Abdou +277
The measurement of muon energy is critical for many analyses in large Cherenkov detectors, particularly those that involve separating extraterrestrial neutrinos from the atmospheri…
Lateral Distribution of Muons in IceCube Cosmic Ray Events
IceCube Collaboration, R. Abbasi, Y. Abdou +277
In cosmic ray air showers, the muon lateral separation from the center of the shower is a measure of the transverse momentum that the muon parent acquired in the cosmic ray interac…
IceTop: The surface component of IceCube
IceCube Collaboration, R. Abbasi, Y. Abdou +280
IceTop, the surface component of the IceCube Neutrino Observatory at the South Pole, is an air shower array with an area of 1 km2. The detector allows a detailed exploration of the…
System-size and centrality dependence of charged kaon and pion production in nucleus-nucleus collisions at 40A GeV and158A GeV beam energy
NA49 Collaboration, T. Anticic, B. Baatar +74
Measurements of charged pion and kaon production are presented in centrality selected Pb+Pb collisions at 40A GeV and 158A GeV beam energy as well as in semi-central C+C and Si+Si…
Inclusive production of protons, anti-protons, neutrons, deuterons and tritons in p+C collisions at 158 GeV/c beam momentum
The NA49 Collaboration, B. Baatar, G. Barr +22
The production of protons, anti-protons, neutrons, deuterons and tritons in minimum bias p+C interactions is studied using a sample of 385 734 inelastic events obtained with the NA…
Cosmic Ray Composition and Energy Spectrum from 1-30 PeV Using the 40-String Configuration of IceTop and IceCube
IceCube Collaboration, R. Abbasi, Y. Abdou +271
The mass composition of high energy cosmic rays depends on their production, acceleration, and propagation. The study of cosmic ray composition can therefore reveal hints of the or…
Precision Measurement of The Most Distant Spectroscopically Confirmed Supernova Ia with the Hubble Space Telescope
D. Rubin, R. A. Knop, E. Rykoff +25
We report the discovery of a redshift 1.71 supernova in the GOODS North field. The Hubble Space Telescope (HST) ACS spectrum has almost negligible contamination from the host or ne…
System size dependence of particle-ratio fluctuations in Pb+Pb collisions at 158 GeV
T. Anticic, NA49 collaboration
New measurements by the NA49 experiment of the centrality dependence of event-by-event fluctuations of the particle yield ratios (K+K)/(), (p+$\bar{\text p…
An Absence of Neutrinos Associated with Cosmic Ray Acceleration in Gamma-Ray Bursts
IceCube Collaboration, R. Abbasi, Y. Abdou +259
Gamma-Ray Bursts (GRBs) have been proposed as a leading candidate for acceleration of ultra high-energy cosmic rays, which would be accompanied by emission of TeV neutrinos produce…
Constraining Type Ia supernova models: SN 2011fe as a test case
F. K. Roepke, M. Kromer, I. R. Seitenzahl +42
The nearby supernova SN 2011fe can be observed in unprecedented detail. Therefore, it is an important test case for Type Ia supernova (SN Ia) models, which may bring us closer to u…
The Self-Calibrating Hubble Diagram
Ulrich Feindt, Marek Kowalski, Kerstin Paech
As an increasing number of well measured type Ia supernovae (SNe Ia) become available, the statistical uncertainty on w has been reduced to the same size as the systematic uncertai…
