Dark matter electron anisotropy: a universal upper limit

Enrico Borriello, Luca Maccione, Alessandro Cuoco

We study the dipole anisotropy in the arrival directions of high energy CR electrons and positrons (CRE) of Dark Matter (DM) origin. We show that this quantity is very weakly model…

Search for Gravitational Wave Bursts from Six Magnetars

J. Abadie, B. P. Abbott, R. Abbott +765

Soft gamma repeaters (SGRs) and anomalous X-ray pulsars (AXPs) are thought to be magnetars: neutron stars powered by extreme magnetic fields. These rare objects are characterized b…

The exposure of the hybrid detector of the Pierre Auger Observatory

The Pierre Auger Collaboration

The Pierre Auger Observatory is a detector for ultra-high energy cosmic rays. It consists of a surface array to measure secondary particles at ground level and a fluorescence detec…

Discovery of a tight correlation for gamma ray burst afterglows with `canonical' light curves

M. G. Dainotti, R. Willingale, S. Capozziello +2

Gamma Ray Bursts (GRB) observed up to redshifts are fascinating objects to study due to their still unexplained relativistic outburst mechanisms and a possible use to test co…

PAMELA results on the cosmic-ray antiproton flux from 60 MeV to 180 GeV in kinetic energy

PAMELA Collaboration, O. Adriani, G. C. Barbarino +61

The satellite-borne experiment PAMELA has been used to make a new measurement of the cosmic-ray antiproton flux and the antiproton-to-proton flux ratio which extends previously pub…

Predictions for the Rates of Compact Binary Coalescences Observable by Ground-based Gravitational-wave Detectors

LIGO Scientific Collaboration, Virgo Collaboration, J. Abadie +709

We present an up-to-date, comprehensive summary of the rates for all types of compact binary coalescence sources detectable by the Initial and Advanced versions of the ground-based…

Search for gravitational-wave inspiral signals associated with short Gamma-Ray Bursts during LIGO's fifth and Virgo's first science run

The LIGO Scientific Collaboration, the Virgo Collaboration, J. Abadie +665

Progenitor scenarios for short gamma-ray bursts (short GRBs) include coalescenses of two neutron stars or a neutron star and black hole, which would necessarily be accompanied by t…

Gamma ray flares from Mrk421 in 2008 observed with the ARGO-YBJ detector

G. Aielli et al.

In 2008 the blazar Markarian 421 entered a very active phase and was one of the brightest sources in the sky at TeV energies, showing frequent flaring episodes. Using the data of A…

Measurement of the energy spectrum of cosmic rays above 10^18 eV using the Pierre Auger Observatory

The Pierre Auger Collaboration

We report a measurement of the flux of cosmic rays with unprecedented precision and statistics using the Pierre Auger Observatory. Based on fluorescence observations in coincidence…

A statistical procedure for the identification of positrons in the PAMELA experiment

O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +58

The PAMELA satellite experiment has measured the cosmic-ray positron fraction between 1.5 GeV and 100 GeV. The need to reliably discriminate between the positron signal and proton…
