Broadband emission of microquasar remnants
Leandro Abaroa, Gustavo E. Romero, Valentí Bosch-Ramon
Microquasar remnants (MQRs), the long-lived cocoons inflated by extinct microquasar jets, have recently been proposed as hidden Galactic PeVatrons capable of producing ultra-high-e…
Large-scale emission from gamma-ray binaries: the case of LS 5039
J. R. Martinez, V. Bosch-Ramon
Abridged abstract: Context: Gamma-ray binaries hosting a non-accreting neutron star and a massive star exhibit multi-wavelength emission on different spatial scales. The interactio…
A cooler look at the environment of Cygnus X-1: Searching for dynamical interactions within cold molecular gas
Pau Bosch-Cabot, Alexandra J. Tetarenko, Valentà Bosch-Ramon +7
We present IRAM--30m observations aimed at identifying potential outflow-interstellar medium interaction sites in the vicinity of the black hole X-ray binary Cygnus X--1, which dis…
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…
Long-term study of the gamma-ray emission of Cygnus X-3 with MAGIC and Fermi-LAT
K. Abe, S. Abe, J. Abhir +185
Cygnus X-3 is a microquasar composed of a compact object of unknown nature closely orbiting around a Wolf-Rayet star. The particularities of this source make it a unique case among…
Microquasar remnants as reservoirs of PeV cosmic rays
Leandro Abaroa, Gustavo E. Romero, Valentà Bosch-Ramón
The Large High Altitude Air Shower Observatory (LHAASO) has revealed a population of Galactic gamma-ray sources radiating beyond 100 TeV, but the nature of several of them is still…
