Constraining leptonic and hadronic gamma-ray emission from HESS J1825-137 and its environment
Rubens Costa, R. C. Anjos
We present a broadband spectral analysis of the -ray emission from the pulsar wind nebula HESS~J1825137, combining observations from Fermi Large Area Telescope (\textit{Fermi…
Prospects for -ray observations of the Perseus galaxy cluster with the Cherenkov Telescope Array
The Cherenkov Telescope Array Consortium, :, K. Abe +564
Galaxy clusters are expected to be dark matter (DM) reservoirs and storage rooms for the cosmic-ray protons (CRp) that accumulate along the cluster's formation history. Accordingly…
Sensitivity of the Cherenkov Telescope Array to spectral signatures of hadronic PeVatrons with application to Galactic Supernova Remnants
The Cherenkov Telescope Array Consortium, F. Acero, A. Acharyya +356
The local Cosmic Ray (CR) energy spectrum exhibits a spectral softening at energies around 3~PeV. Sources which are capable of accelerating hadrons to such energies are called hadr…
Probing extreme environments with the Cherenkov Telescope Array
C. Boisson, A. M. Brown, A. Burtovoi +127
The physics of the non-thermal Universe provides information on the acceleration mechanisms in extreme environments, such as black holes and relativistic jets, neutron stars, super…
Multi-messenger and transient astrophysics with the Cherenkov Telescope Array
Ž. Bošnjak, A. M. Brown, A. Carosi +142
The discovery of gravitational waves, high-energy neutrinos or the very-high-energy counterpart of gamma-ray bursts has revolutionized the high-energy and transient astrophysics co…
Measurement of the fluctuations in the number of muons in extensive air showers with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +365
We present the first measurement of the fluctuations in the number of muons in extensive air showers produced by ultrahigh energy cosmic rays. We find that the measured fluctuation…
Design, upgrade and characterization of the silicon photomultiplier front-end for the AMIGA detector at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +357
AMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory to complement the study of ultra-high-energy cosmic rays (UHECR) by measuring the…
Acceleration of charged particles from near-extremal rotating black holes embedded in magnetic fields
C. H. Coimbra-Araújo, R. C. Anjos
The aim of the present article is to evaluate the motion of charged test particles in the vicinity of a near-extremal rotating black hole in the presence of magnetic fields. Euler-…
Galactic Centre as an efficient source of cosmic rays
Rita C. Anjos, Fernando Catalani
After the discovery of Fermi Bubbles and the excess of gamma-ray emission, the Galactic Centre has received increasing attention with the aim to understand its role in the origin a…
Observation of inclined EeV air showers with the radio detector of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +392
With the Auger Engineering Radio Array (AERA) of the Pierre Auger Observatory, we have observed the radio emission from 561 extensive air showers with zenith angles between 60$^\ci…
Indication of anisotropy in arrival directions of ultra-high-energy cosmic rays through comparison to the flux pattern of extragalactic gamma-ray sources
The Pierre Auger Collaboration, A. Aab, P. Abreu +390
A new analysis of the dataset from the Pierre Auger Observatory provides evidence for anisotropy in the arrival directions of ultra-high-energy cosmic rays on an intermediate angul…
Inferences on Mass Composition and Tests of Hadronic Interactions from 0.3 to 100 EeV using the water-Cherenkov Detectors of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +403
We present a new method for probing the hadronic interaction models at ultra-high energy and extracting details about mass composition. This is done using the time profiles of the…
Spectral Calibration of the Fluorescence Telescopes of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +403
We present a novel method to measure precisely the relative spectral response of the fluorescence telescopes of the Pierre Auger Observatory. We used a portable light source based…
Upper limits on the total cosmic-ray luminosity of individual sources
R. C. Anjos, V. de Souza, D. A. Supanitsky
In this paper, upper limits on the total luminosity of ultra-high-energy cosmic rays (UHECR) (E > eV) are determined for five individual sources. The upper limit on the i…
