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…
UHECRs Propagation and their Multimessengers: Upper limits and the Impact of the Extragalactic Magnetic Field
Rodrigo Sasse, Rubens Costa, Adriel G. B Mocellin +2
The detection of high-energy astrophysical multimessengers establishes a connection between ultra-high-energy cosmic rays (UHECRs) and powerful cosmic accelerators. Interactions of…
Blazars Jets and prospects for TeV-PeV neutrinos & gamma-rays through cosmic-ray interactions
Rodrigo Sasse, Rubens Jr. Costa, Luiz A. Stuani Pereira +1
This study explores the origins of cosmic rays and their secondary messengers, focusing on the potential role of four BL Lacs W Comae, 1ES 1959+650, PKS 2005-489, and PKS 2155-304…
A gamma-ray study of galactic PeVatron candidates LHAASO J1825-1326 and LHAASO J1839-0545
Rubens Jr. Costa, Débora B. Götz, Rita C. Anjos +2
Recent studies by LHAASO have shown the presence of high-luminosity PeVatrons in our Galaxy. We examine two notable sources, each consisting of two pulsars, detected by LHAASO. We…
Probing Low-Luminosity Gamma-Ray Emission from SNR G296.5+10.0 and CCO 1E 1207.4-5209 with CTAO
Luana N. Padilha, Rubens Jr. Costa, Rita C. dos Anjos +1
The acceleration mechanisms of cosmic rays (CR) in supernova remnants (SNRs) and their associated compact central objects (CCOs) remain an open question in high-energy astrophysics…
