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…

Multi-messenger characterization of Mrk 501 during historically low X-ray and -ray activity

MAGIC collaboration, H. Abe, S. Abe +322

We study the broadband emission of Mrk 501 using multi-wavelength observations from 2017 to 2020 performed with a multitude of instruments, involving, among others, MAGIC, Fermi-LA…

Bounds from multi-messenger astronomy on the Super Heavy Dark Matter

M. Deliyergiyev, A. Del Popolo, Morgan Le Delliou

The purely gravitational evidence supporting the need for dark matter (DM) particles is compelling and based on Galactic to cosmological scale observations. Thus far, the promising…

Search for photons above 10 eV with the surface detector of the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +365

We use the surface detector of the Pierre Auger Observatory to search for air showers initiated by photons with an energy above eV. Photons in the zenith angle range from…

The effect of magnetic field on the inner Galactic rotation curve

Man Ho Chan, Antonino Del Popolo

In the past few decades, some studies pointed out that magnetic field might affect the rotation curves in galaxies. However, the impact is relatively small compared with the effect…

Cosmological implications of photon-flux upper limits at ultra-high energies in scenarios of Planckian-interacting massive particles for dark matter

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

Using the data of the Pierre Auger Observatory, we report on a search for signatures that would be suggestive of super-heavy particles decaying in the Galactic halo. From the lack…

Investigating Hadronic Interactions at Ultra-High Energies with the Pierre Auger Observatory

Isabel Goos, :, P. Abreu +374

The development of an extensive air shower depends not only on the nature of the primary ultra-high-energy cosmic ray but also on the properties of the hadronic interactions. For e…

A Mass Dependent Density Profile from Dwarfs to Clusters

Antonino Del Popolo, Morgan Le Delliou

In this paper, we extend the work of Freundlich et al. 2020 who showed how to obtain a Dekel-Zhao density profile with mass dependent shape parameters in the case of galaxies. In t…

There is no universal acceleration scale in galaxies

Man Ho Chan, Shantanu Desai, Antonino Del Popolo

Recently, many studies seem to reveal the existence of some correlations between dark matter and baryonic matter. In particular, the unexpected tight Radial Acceleration Relation (…

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…
