Ultra-High-Energy Particle Production in Binary Mergers Endowed with Magnetic Fields
Carlos H. Coimbra-Araujo, Rita C. Anjos, Jonas P. Pereira +1
We study the production of ultra-high-energy particles via the Bañados--Silk--West (BSW) mechanism in the pre-merger phase of binary systems detected by LIGO-Virgo-KAGRA. By solvin…
Non-thermal emission from the vicinity of the magnetar CXOU J171405.7-381031
Manoel F. Sousa, Rita. C. Anjos
Magnetars are neutron stars with ultra-strong magnetic fields (- G) and are promising candidates for high-energy particle acceleration. We present a multiw…
Centaurus A Inner Lobes -- I. Hydrodynamic modeling of a Precessing Jet
Rita C. Anjos, Brian Reville
We present a numerical investigation into the precessing jets of the inner lobes of Centaurus A, focusing on their dynamical evolution and interaction with the surrounding medium.…
High-Synchrotron-Peaked BL Lacs as Multi-Messenger Sources: Connecting Ultra-High-Energy Cosmic Rays and Neutrinos
Luiz Augusto Stuani Pereira, Rita C. Anjos
High-synchrotron-peaked (HSP) BL Lac objects are extreme particle accelerators whose synchrotron emission peaks at high frequencies, typically in the UV-to-X-ray band ($ν_{\rm peak…
FR0 radio galaxy jets -- I. linking jet dynamics and high-energy emission in LEDA 55267 and LEDA 58287
André F. S. Cardoso, Rita C. Anjos
Fanaroff-Riley type 0 (FR0) radio galaxies host anomalously compact jets whose disruption mechanism and high-energy emission remain poorly understood. We combine three-dimensional…
Oblique Shocks at Supernova Remnants in Massive Star Clusters: A Model for the Cosmic-Ray Knee Observed by LHAASO
Luana N. Padilha, Rita C. Anjos
This work establishes oblique shocks in Massive Star Clusters (MSC) as a primary mechanism for accelerating cosmic rays (CR) up to the knee of the energy spectrum. We develop a mod…
Massive Star Clusters as sources of high-energy gamma radiation
Luana N. Padilha, Rita C. Anjos
This paper investigates the contribution of massive star clusters (MSC) as sources of high-energy gamma rays and their impact on the ultra-high-energy (UHE) emission observed throu…
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…
