Dark Matter Boosted by Terrestrial Collisions

Zamiul Alam, Christopher V. Cappiello, Francesc Ferrer

Inelastic dark matter (IDM) models feature an energy threshold for scattering with Standard Model particles, which enables their consistency with the increasingly stringent limits…

Gravitational Waves from First-Order Phase Transition in a Simple Axion-Like Particle Model

P. S. Bhupal Dev, Francesc Ferrer, Yiyang Zhang +1

We consider a gauge-singlet complex scalar field with a global symmetry that is spontaneously broken at some high energy scale . As a result, the angular part of th…

Atmospheric effects on extensive air showers observed with the Surface Detector of the Pierre Auger Observatory

The Pierre Auger Collaboration

Atmospheric parameters, such as pressure (P), temperature (T) and density, affect the development of extensive air showers initiated by energetic cosmic rays. We have studied the i…

Limit on the diffuse flux of ultra-high energy tau neutrinos with the surface detector of the Pierre Auger Observatory

The Pierre Auger Collaboration

Data collected at the Pierre Auger Observatory are used to establish an upper limit on the diffuse flux of tau neutrinos in the cosmic radiation. Earth-skimming may interact…

Observation of the suppression of the flux of cosmic rays above 4x10^19eV

The Pierre Auger Collaboration

The energy spectrum of cosmic rays above 2.5x10^18eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the flux, J ~ E…

Upper limit on the cosmic-ray photon flux above 10^19 eV using the surface detector of the Pierre Auger Observatory

The Pierre Auger Collaboration

A method is developed to search for air showers initiated by photons using data recorded by the surface detector of the Auger Observatory. The approach is based on observables sens…

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…

Correlation of the highest energy cosmic rays with nearby extragalactic objects

The Pierre Auger Collaboration

Using data collected at the Pierre Auger Observatory during the past 3.7 years, we demonstrated a correlation between the arrival directions of cosmic rays with energy above ~ 6x10…

Anisotropy studies around the galactic centre at EeV energies with the Auger Observatory

The Pierre Auger Collaboration

Data from the Pierre Auger Observatory are analyzed to search for anisotropies near the direction of the Galactic Centre at EeV energies. The exposure of the surface array in this…

An upper limit to the photon fraction in cosmic rays above 10^19 eV from the Pierre Auger Observatory

Pierre Auger Collaboration

An upper limit of 16% (at 95% c.l.) is derived for the photon fraction in cosmic rays with energies greater than 10^19 eV, based on observations of the depth of shower maximum perf…
