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…
Constraining Dark Matter Properties with Gamma-Rays from the Galactic Center with Fermi-LAT
Nicolas Bernal, Sergio Palomares-Ruiz
We study the capabilities of the Fermi-LAT instrument on board of the Fermi mission to constrain particle dark matter properties, as annihilation cross section, mass and branching…
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…
The nonlinear saturation of the non-resonant kinetically driven streaming instability
L. Gargate, R. A. Fonseca, J. Niemiec +3
A non-resonant instability for the amplification of the interstellar magnetic field in young Supernova Remnant (SNR) shocks was predicted by Bell (2004), and is thought to be relev…
Measurement of the Depth of Maximum of Extensive Air Showers above 10^18 eV
The Pierre Auger Collaboration
We describe the measurement of the depth of maximum, Xmax, of the longitudinal development of air showers induced by cosmic rays. Almost four thousand events above 10^18 eV observe…
Mass-radius relation for magnetized strange quark stars
A. Perez Martinez, R. Gonzalez Felipe, D. Manreza Paret
We review the stability of magnetized strange quark matter (MSQM) within the phenomenological MIT bag model, taking into account the variation of the relevant input parameters, nam…
