Constraining the sources of ultra-high-energy cosmic rays across and above the ankle with the spectrum and composition data measured at the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +365

In this work we present the interpretation of the energy spectrum and mass composition data as measured by the Pierre Auger Collaboration above eV. We use an ast…

(Anti)kaon condensation in strongly magnetized dense matter

Debraj Kundu, Vivek Baruah Thapa, Monika Sinha

Recent observations of several massive pulsars, with masses near and above , point towards the existence of matter at very high densities, compared to normal matter that…

Arrival Directions of Cosmic Rays above 32 EeV from Phase One of the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +372

A promising energy range to look for angular correlation between cosmic rays of extragalactic origin and their sources is at the highest energies, above few tens of EeV ($1\:{\rm E…

Standard cooling of rapidly rotating isolated neutron stars in 2D

Mikhail V. Beznogov, Jérôme Novak, Dany Page +1

We study the thermal evolution of axisymmetric rotating neutron stars in full general relativity. To this aim we develop "NSCool 2D Rot", a major upgrade of the 1D neutron stars th…

A search for photons with energies above eV using hybrid data from the low-energy extensions of the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +373

Ultra-high-energy photons with energies exceeding eV offer a wealth of connections to different aspects of cosmic-ray astrophysics as well as to gamma-ray and neutrino as…

Limits to gauge coupling in the dark sector set by the non-observation of instanton-induced decay of Super-Heavy Dark Matter in the Pierre Auger Observatory data

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374

Instantons, which are non-perturbative solutions to Yang-Mills equations, provide a signal for the occurrence of quantum tunneling between distinct classes of vacua. They can give…

A "Hyperburst" in the MAXI J0556-332 Neutron Star: Evidence for a New Type of Thermonuclear Explosion

Dany Page, Jeroen Homan, Martin Nava-Callejas +5

The study of transiently accreting neutron stars provides a powerful means to elucidate the properties of neutron star crusts. We present extensive numerical simulations of the evo…

Testing effects of Lorentz invariance violation in the propagation of astroparticles with the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +374

Lorentz invariance violation (LIV) is often described by dispersion relations of the form with delta different based on particle type , with…

Search for Spatial Correlations of Neutrinos with Ultra-High-Energy Cosmic Rays

The ANTARES collaboration, A. Albert, S. Alves +1042

For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question of high-energy astrophysics. One approach for solving this puzzle is to corr…
