Multiwavelength study of non-thermal emission in the Swift J1834.9-0846/W41 region
Manoel F. Sousa, Rita C. Dos Anjos, Vitor de Souza
The paper models the broadband non‑thermal emission from the Swift J1834.9‑0846/W41 region, comparing leptonic and lepto‑hadronic scenarios and finding that a lepto‑hadronic model…
Effects of Lorentz invariance violation on charged particles and photon production in astrophysical sources
Matheus Duarte, Vitor de Souza
We investigate the impact of Lorentz invariance violation (LIV) on radiation processes in astrophysical sources, focusing on synchrotron and inverse Compton interactions. We derive…
Recent advances on multimessenger astrophysics: Centaurus A, GW 170817, and KM3-230213A
Cainã de Oliveira, Vitor de Souza
We review recent advances in multimessenger astrophysics, with particular emphasis on Centaurus A and on two pivotal events: the gravitational-wave detection GW 170817 and the ultr…
Probing late-time annihilations of oscillating asymmetric dark matter via rotation curves of galaxies
Júlia G. Mamprim, Guillermo Gambini, Luan B. Arbeletche +2
In this paper, we explore the Oscillating Asymmetric Dark Matter (OADM) model to address the core-cusp problem, aiming to resolve the discrepancy between the predictions of the $Î…
Investigating the effect of hadronic models on IACT images
Benedetta Bruno, Rodrigo Guedes Lang, Luan Bonneau Arbeletche +2
The predictions of hadronic interaction models for cosmic-ray induced air showers contain inherent uncertainties due to limitations of available accelerator data. This leads to dif…
Prospects for the detection of Dark Matter with Long-lived Mediators in the Sun using the Southern Wide-field Gamma-ray Observatory
Micael Andrade, Juan Fagiani, Clarissa Siqueira +2
The operation of the next generation of gamma-ray observatories will lead to a great advance in dark matter searches. In this paper, we use the hidden sectors hypothesis within the…
