A one-parameter two-zone leptonic model for the blazar sequence
Stella Boula, Apostolos Mastichiadis, Demosthenes Kazanas
Blazars, a subclass of radio-loud active galactic nuclei with relativistic jets aligned close to our line of sight, emit highly variable non-thermal radiation across the electromag…
An expanding one-zone model for studying blazars emission
Stella S. Boula, Apostolos Mastichiadis
Context.Blazars, a sub-category of Active Galactic Nuclei, are characterized by their non-thermal variable emission. This emission extends over the whole electromagnetic spectrum a…
A roadmap to hadronic supercriticalities: a comprehensive study of the parameter space for high-energy astrophysical sources
Apostolos Mastichiadis, Ioulia Florou, Elina Kefala +2
Hadronic supercriticalities are radiative instabilities that appear when large amounts of energy are stored in relativistic protons. When the proton energy density exceeds some cri…
On the connection of radio and -ray emission in blazars
Stella Boula, Maria Petropoulou, Apostolos Mastichiadis
Blazars are a sub-category of radio-loud active galactic nuclei with relativistic jets pointing towards to the observer. They are well-known for their non-thermal variable emission…
Accretion Disk MHD Winds and Blazar Classification
Stella Boula, Demosthenes Kazanas, Apostolos Mastichiadis
The Fermi Gamma-Ray Space Telescope observations of blazars show a strong correlation between the spectral index of their gamma-ray spectra and their synchrotron peak frequency $ν_…
