First fast radio burst search campaign at the Argentine Institute of Radio Astronomy
Carlos O. Lousto, Harsh Prajapati, Ezequiel Zubieta +9
Fast radio bursts (FRBs) are intense millisecond-duration radio transients of extragalactic origin whose physical nature remains under active investigation, and which also serve as…
Enabling population studies on wind-driven Galactic binary systems
B. Marcote, P. Benaglia, V. Bosch-Ramon +8
Galactic binaries driven by stellar wind shocks, such as colliding wind binaries (CWBs) and gamma-ray binaries (gBs), harbor one of the most efficient particle acceleration engines…
Investigating particle acceleration in the Wolf-Rayet bubble NGC 2359
Anindya Saha, Anandmayee Tej, Santiago del Palacio +4
Massive stars have been proposed as candidates to be major factories of Galactic cosmic rays (GCRs). However, this claim lacks enough empirical evidence, especially for isolated st…
Foreground and internal free-free absorption in particle-accelerating colliding-wind binaries : Insights from the radio emission of WR 147
M. Tasseroul, M. De Becker, A. B Blanco +2
Radio emission from massive binary systems is generally of composite nature, showing both a thermal emission component from the winds and a non-thermal component from relativistic…
Probing the detectability of electromagnetic signatures from Galactic isolated black holes
Javier Rodrigo Martinez, Valenti Bosch-Ramon, Florencia Laura Vieyro +1
Context: A large number of isolated black holes (IBHs) are expected to populate the Galaxy. However, only one has been confirmed by the analysis of a microlensing event, and no con…
Radio study of the colliding wind binary HD93129A near periastron and its surroundings
Paula Benaglia, Santiago del Palacio, Juliana Saponara +3
HD93129A is an O+O stellar system whose CWR has been mapped by high angular resolution observations at cm wavelengths. The synchrotron nature of the radio emission confirms its par…
