Hadronic signatures from magnetically dominated baryon-loaded AGN jets
Maria Petropoulou, Filippos Psarras, Dimitrios Giannios
Blazars are a rare class of active galactic nuclei (AGN) with relativistic jets pointing towards the observer. Jets are thought to be launched as Poynting-flux dominated outflows t…
Radio emission from colliding outflows in high-mass X-ray binaries with strongly magnetized neutron stars
Margaritis Chatzis, Maria Petropoulou, Georgios Vasilopoulos
We present a toy model for radio emission in HMXBs with strongly magnetized neutron stars (NS) where a wind-collision region is formed by the NS outflow and the stellar wind of the…
Confronting observations of VHE gamma-ray blazar flares with reconnection models
J. Jormanainen, T. Hovatta, E. Lindfors +3
Several models have been suggested to explain the fast gamma-ray variability observed in blazars, but its origin is still debated. One scenario is magnetic reconnection, a process…
Probing Neutrino Emission from X-ray Blazar Flares observed with Swift-XRT
Stamatios I. Stathopoulos, Maria Petropoulou, Paolo Giommi +3
Blazars are the most extreme subclass of active galactic nuclei with relativistic jets emerging from a super-massive black hole and forming a small angle with respect to our line o…
The Blazar Hadronic Code Comparison Project
Matteo Cerruti, Michael Kreter, Maria Petropoulou +15
Blazar hadronic models have been developed in the past decades as an alternative to leptonic ones. In hadronic models the gamma-ray emission is associated with synchrotron emission…
A numerical study of long-term multi-wavelength blazar variability
M. Polkas, M. Petropoulou, G. Vasilopoulos +4
Decade-long monitoring of blazars at optical and infrared (OIR) wavelengths with the Small and Moderate Aperture Research Telescope System (SMARTS) in Chile and in -rays with th…
