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…
Thackeray's globules in IC 2944: the rocket effect revisited by ALMA
M. Fernández-López, L. A. Zapata, B. Reipurth +4
The prominent Thackeray's globules are a collection of cloudlets seen in silhouette against the bright emission of the IC 2944 HII region, ionized by the Collinder 249 cluster of e…
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…
High resolution radio analysis of the starburst galaxy NGC 4527: signatures of an AGN core
C. A. Galante, G. E. Romero, J. Saponara +1
NGC 4527 is a nearby edge-on spiral galaxy with both starburst and AGN features, hosting a LINER nucleus. We present a radio study of the large-scale structure and nuclear region o…
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…
