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…
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…
Double White Dwarf Mergers as Progenitors of Long-Period Transients
Manuel Malheiro, Sarah V. Borges, Jaziel G. Coelho +6
There is an ongoing discussion in the literature on the nature of long-period transients (LPTs), radio-emitting sources with periods ranging from hundreds to tens of thousands of s…
Parameter Estimation Precision with Geocentric Gravitational Wave Interferometers: Monochromatic Signals
Manoel Felipe Sousa, Tabata Aira Ferreira, Massimo Tinto
We present a Fisher information matrix study of the parameter estimation precision achievable by a class of future space-based, "mid-band", gravitational wave (GW) interferometers…
Prospects for gamma-ray emission from magnetar regions in CTAO observations
M. F. Sousa, R. Jr. Costa, Jaziel G. Coelho +1
Recent multi-wavelength observations have highlighted magnetars as significant sources of cosmic rays, particularly through their gamma-ray emissions. This study examines three mag…
